NETGEAR keeps the tradition coming with their network infrastructure

For a long time, NETGEAR have been known for offering cost-effective hubs and switches for use with twisted-pair wired Ethernet segments in homes and small businesses. In the early days, this meant very small five-port unmanaged 10/100Mbps hubs and switches that didn’t cost much and could allow you to easily consider wiring for Ethernet.

To the same extent, they released a 56k dial-up modem router with an integrated four-port hub which was the first product of its kind to offer dial-up Internet across a network without the need for a computer to be running. But it was considered a product ahead of its time thanks to ADSL or cable broadband Internet not being available in many areas and not many home networks being set up for the Internet. But it led on to some of the most capable NETGEAR modem routers to surface like the DG834G which had won a significant amount of accolades in its day.

Subsequently they were one of the first companies to offer some affordable unmanaged Gigabit switches that can be a Power-Over-Ethernet power-source device. This was offered on half of the ports on these devices but they gradually offered some Web-managed models that had all of the ports covered.

Another approach was to offer Web-managed Ethernet switches that had a focus on ease-of-use. This was about a “big-business” feature where an Ethernet network can be managed to do things like manage quality-of-service or segment a LAN for further control. But NETGEAR’s approach not just provided the Web-based dashboard on each of these switches but provided an “automatic-transmission” approach to quality-of-service management in a manner to make this concept appeal to the small network. One of these switches that NETGEAR offered was even designed to be able to be powered using Power-Over-Ethernet, something that could appeal to “regional” switches or those devices serving a cluster of network equipment at a table or desk.

But NETGEAR took this concept further with a gaming-grade network switch that has the features of a business-grade network switch but is pitched towards gamers and multimedia enthusiasts. The Nighthawk S8000 Web-managed switch has the ability to be managed like the typical business-grade managed switch but invokes the “automatic transmission” approach like some other NETGEAR switches for QoS management. It is presented in a style that makes it attractive to use in the home entertainment centre where a 4K UHDTV, XBox One or PS4, and similar devices are installed and you want something better than Wi-Fi for online gaming or video streaming at Full HD or 4K UHD.

This unit even implements link aggregation / port-trunking for up to four Ethernet ports so that the Nighthawk S8000 switch can be purposed as an “off-ramp” for a high-speed link to a gaming rig, router or NAS with this kind of connectivity. In this case, the bandwidth offered by the aggregated ports is treated as one high-speed link. Let’s not forget that this unit can be integrated into a sophisticated VLAN-driven network and NETGEAR put a tentative price of US$99.99 for this unit intended to be released around March 2017.

The goal with all of these products is to offer something that could be considered only fit for big business but at a cost-effective price and with an approach that reduces operational complexity.

Solwise adds Power Over Ethernet Plus and HomePlug AV2 in a single device

Solwise PL-1200AV2-POE HomePlug adaptor product picture courtesy of Solwise

Solwise PL-1200AV2-POE HomePlug adaptor combines HomePlug AV2 MIMO and 802.3at Power-Over-Ethernet in one device

In 2013, Solwise became the first to offer for the UK market a “homeplug” that could work “best case” with a HomePlug AV500 segment and provide power to Ethernet-connected devices “over the blue wire” using the 802.3af Power-Over-Ethernet standard.

Now this UK-based network-equipment supplier have raised the bar with a Power-Over-Ethernet “homeplug” which works to the HomePlug AV2 MIMO 1200Mbps standard. This high-throughput standard offers a more robust powerline network link highly suitable for multiple-building setups like this example or small business and community organisations using HomePlug technology for temporary or semi-permanent networks in traditional business-grade premises. It is facilitated by use of all three wires (phase/active/line, neutral and earth/ground) of the standard AC plug to transfer the data along with the other improvements associated with high-throughput, robust data transfer.

Power Over Ethernet concept

Power Over Ethenrt concept

But wait, there’s more! This GBP£74.78 device doesn’t just provide Power-Over-Ethernet power through its Gigabit Ethernet port according to the baseline 802.3af standard but to the high-power 802.3at Power-Over-Ethernet-Plus standard. This can allow for multiple-band multiple-radio access points answering to 802.11ac standards, highly-powerful access points or IP videosurveillance cameras that can yield high-quality pictures.

This Solwise device could allow for a two-piece HomePlug AV2 access point setup with this ceiling-mount 802.11ac 1350Mbps access point (GBP£71.40), this ceiling-mount 802.11ac 1750Mbps access point (GBP£118.36), the “smoke-alarm” 802.11n 900Mbps access point (GBP£70.14), the IP55-compliant (weatherproof) outdoor 802.11ac 1200Mbps access point (GBP£175.24) or the IP55-compliant (weatherproof) outdoor 802.11ac 1750Mbps access point (GBP£186.66).

HomePlug link between house and garage

Perfect for this kind of setup

As well, the Solwise HomePlug AV2 Power-Over-Ethernet-Plus adaptor  could facilitate surveillance of your outbuildings like your garage where the classic car is being kept, the shed where you have those precious tools or the barn where your livestock are being kept when you team it with this traditional-style IP66-compliant (weatherproof) “bullet-style” 1 megapixel standards-based infrared-capable IP camera (GBP£164.92).

The fact that this Solwise “homeplug” combines HomePlug AV2 MIMO and 802.3at Power-Over-Ethernet Plus opens up a lot more possibilities for what both these technologies offer.

My Comments

NETGEAR had faced a serious problem with some of its recent-model routers due to a security exploit in the firmware that drives these network-Internet “edge” devices. Previous coverage about this issue had required you to use another router for your home network to stay secure.

This has had NETGEAR rush out firmware updates for each of these affected routers in order to mitigate the recently-discovered security exploit.

A problem that besets most of the commonly-available home-network bardware is that firmware updating requires you to visit the manufacturer’s site, download the firmware as a special file package for your device, then upload that package to your device via its Web-based management interface. This can daunt some computer users who haven’t much experience with these kind of hardware maintenance tasks.

Personally, I would like to see steps taken to support automatic firmware upgrades such as what AVM are doing with their Fritz!Box devices, or at least the ability to click on a button in the management interface to start the download and update process for the device’s firmware. This is a practice that is being implemented in most of the European-made modem routers, along with most consumer-electronics devices like Smart TVs and set-top video peripherals.

There is also the issue of protecting the update files so that you aren’t installing malware on your device and it may involve processes like authenticity checks for software delivered as part of a firmware update or functionality add-on.

The update procedure

The update procedure will require you to download the updated firmware package using your regular desktop or laptop computer. Here, they recommend that you connect your regular computer directly to the router using an Ethernet cable if you can do so for the download and update process to be sure that this process works reliably.

Follow the link listed in this article to the NETGEAR-hosted support page for your router’s model. You will see the link for the firmware package you need to download. Here, you download that firmware package to your “downloads” folder.

Then, once you have downloaded the firmware from the NETGEAR site, you log in to your router’s management page from that same computer using your favourite Web browser. For these routers, the URL is http://www.routerlogin.net. Subsequently, you have to visit the ADVANCED tab, then the Administration option, then the Firmware Upgrade option.

In that screen, you click the Browse button, which will pop up a file-system dialog box where you have to find the firmware file that you downloaded in your “downloads” folder. Once you have selected the firmware file, click the Upload button to transfer the firmware to your router, whereupon it will commence the updating process. Leave the router alone during this process so as not to interrupt this critical process. You will see a progress bar to indicate how the upgrade is progressing.

Once this update procedure is done, a good practice would be to regularly visit NETGEAR’s support pages for your particular router and check for newer firmware on a regular basis. Then, if there is newer firmware available for your device, update it following the instructions on their Website or the general instructions listed in this article.

Conclusion

The increased awareness by industry and computer media regarding software quality and data security for dedicated-purpose devices connected to the Internet along with consumer / small-business network-infrastructure devices is going to make companies who design these devices or the software that runs them wake up regarding these issues.

My Comments

A new direction that is being looked at for the Wi-Fi wireless-network ecosystem is the use of “passive Wi-Fi”. This is where Wi-Fi endpoints will not be needing the use of analogue RF amplification circuitry and can simply reflect these wireless signals back to access points or routers.

Traditional active Wi-Fi setups work analogously to a torch (flashlight) that is being used where it is actively putting out the light thanks to its batteries. But passive Wi-Fi works in a similar vein to a mirror that simply reflects the light without using any energy.

The advantage here with passive Wi-Fi is that devices implementing that technology don’t need to draw lots of current for them to operate on the network. This is so appealing towards mobile devices implementing it as a battery-saving measure.

But it also appeals towards how devices related to the smart home or Internet-Of-Things will be designed. This is because these devices can be designed to work for a long time on up to three AA or AAA Duracells or a coin battery, or could use energy-harvesting technologies like solar power or kinetic energy but work with a Wi-Fi network rather than the Bluetooth LE, Zigbee or Z-Wave networks that are optimised for low energy.

Here, it may be feasible to directly connect these devices to your home network and the Internet without the need to use bridge devices to achieve this goal. This is although it can be feasible to integrate Bluetooth LE, Zigbee and/or Z-Wave bridging functionality in to a Wi-Fi-capable router or access point, especially if there is a market expectation to have these devices also serve as “smart-home” or “IoT” hubs.

At the moment, passive Wi-Fi can work between 30-100 feet on a line-of-sight or through walls while passing a bandwidth of up to 11Mbps. The prototypes have been demonstrated with traditional Wi-Fi network equipment including a router and smartphone and this has proven that they can work in a standard Wi-Fi network. But there have been issues raised about requiring routers and access points to broadcast a “wake-up” call for these devices to report their presence and status.

A question that can be asked as this technology is designed is whether it could be feasible to design a Wi-FI front-end to switch between active and passive mode. Here, it could appeal to devices that enter passive mode simply to save energy but “go active” while in use with obvious use cases being mobile devices or Wi-Fi-based handheld controllers.

What it could lead to is that the goal to optimise all of the building-wide wireless-data technologies for low-power use has been nearly completed with the ability to have devices that exploit these technologies able to run for a long time on ordinary batteries.

Advanced business Wi-Fi–what needs to be done

OpenMesh managed access point product picture courtesy of OpenMesh

OpenMesh managed wireless access point

A class of Wi-Fi network setup that is appearing in the business networking market is what I would describe at best, “advanced” Wi-Fi. This typically is positioned as “managed Wi-Fi” or “virtualised Wi-Fi” due to the way these systems can be managed to suit business requirements or set up to serve multiple networks.

What does advanced Wi-Fi offer

But what does it offer? These networks are dependent on a Wi-Fi network controller that connects to compatible Wi-Fi access points using a Cat5 Ethernet wired backbone which also links them back to the Internet and other business network resources. Some of these systems may provide this kind of management through a cloud-hosted controller rather than a controller appliance installed on the premises.

The IT department can control these systems using a single dashboard, whether this is in the form of a Web-based front-end or a native client program.

The tricks that these systems have up the sleeve include:

  • the ability to adjust the operating channel, transmit power and other parameters of the access points to achieve the desired network coverage and bandwidth for the whole network;
  • to implement a combination of VLAN (virtual local area network), multiple ESSIDs (wireless network names) and related technologies to allow the same group of Wi-Fi access points to serve multiple networks thus creating a “neutral-host” or “multiple-host” Wi-Fi network; and
  • to work as Wi-Fi intrusion-detection/prevention systems to protect the network’s users against rogue wireless-network activity.

What are the current limitations

But there are limitations that need to be looked at to make this technology viable across all business types.

Lack of vendor independence

One is the lack of vendor independence and interoperability. Here, most of these systems are dependent on hardware and software offered by the same vendor which can be very limiting when a business wants to expand their Wi-Fi network’s footprint or replace end-of-life equipment in their system. It can be especially very frustrating for situations where their vendor doesn’t have an access point that ticks the necessary boxes for a particular application such as, for example, a weatherproof outdoor design that supports dual-band 802.11ac or the software doesn’t support the functionality that a customer is so after.

The same situation can be very frustrating whenever a vendor declares end-of-life for a particular managed-wireless-network platform, ceases to trade or is taken over by someone else. This can raise various support issues whenever you need to replace older equipment or improve on your existing system.

Here, you could end up dumping all of the access points that you bought for an advanced-WiFi setup if you had to change to a new platform or vendor, rather than allowing for a gradual changeover where you can keep existing equipment going.

Systems placing small business out of the equation

As well, not many systems are designed to cater to small-business users who want to effectively “start small” and “grow up”. A classic situation that may occur is for the business to use a single access point or router but as they grow, they add another access point to obtain an increased footprint such as to cover the neighbouring shop they just leased.

Typically, most of the managed Wi-Fi systems require the use of an access-point controller and the compatible access points for them to work. But this could be facilitated through the use of software-based enablement of this functionality for business-grade access points and routers where you only need to download particular software to these devices to add on this functionality.

Such a concept can be facilitated through network-hardware vendors adopting an “app-store” approach where they can offer additional software that a user can download to their network hardware, similar to what happens for smartphones and tablets.

Lack of secure inter-network data exchange abilities

Small businesses - Belgrave shopping strip

Shopping strips and similar developments could benefit from open-frame advanced Wi-Fi setups

Another missing feature is the ability to exchange data between multiple managed wireless networks to permit cohesive operation amongst the multiple networks. What could this feature offer?

Such a feature would benefit building-wide or development-wide wireless-network optimisation for multiple-occupancy developments including to create a “ring of protection” around the building for the occupants’ wireless networks. But it would require that the individual occupants can be able to have control of their networks.

The feature can also support secure authenticated access to private wireless networks via other trusted wireless networks. Such a setup could cover a multiple-occupancy building’s communal areas like lobbies, food courts or garden areas; or for extending private Wi-Fi coverage to business partners’ offices or local “watering holes” like hotels, bars and cafés. The concept here is about creation of a “neutral-host” or “multiple-host” Wi-Fi network in the communal areas or “watering holes” where all of the occupants have access to their networks in the same manner as what would happen when they discover and log in to the Wi-Fi network on their premises.  This situation is becoming increasing real as an increasing number of multiple-occupancy developments are heading towards the “mixed-use” direction where there is office, shopping, entertainment, residential, hotel and/or other space within the same development.

This functionality would require the use of tag-based or port-based VLANs (virtual local-area networks) as a way to link private LANs to the access points, and this may be already in place with multi-occupancy buildings where a business may occupy office and/or retail space across differing floors. Or it can be facilitated on a WAN-based effort through the use of box-to-box VPNs, typically used to link business locations across the world.  There could be the opportunity to have this kind of private-network-access enabled on a long-term basis such as through one’s tenancy or business partnership; or on an “ad-hoc” basis where it is enabled as required such as for a conference.

Less relevance to home-network users

Yarra's Edge apartment blocks

Apartment blocks and other residential developments can benefit from advanced Wi-Fi setups

At the moment, advanced Wi-Fi network technology is not being perceived or pitched as being relevant to home network users even though there is a use case for this technology amongst this user class.

This technology can be made relevant for home networks established in high-density or multiple-dwelling environments including the “mixed-use” development reality that I have outlined above. This is because these kind of environments involve many home and other Wi-Fi networks operated close together through that development.

Such networks can be set up for automatic channel and signal-strength optimisation across a block or street while these networks can be integrated with access points installed in common areas that can provide access to the development’s occupants’ networks on an ad-hoc basis. As well, if a development has one or more businesses or facilities of benefit to all the occupants like a food court, café or bar, the households could “extend” their Wi-Fi network to the meeting place for the duration they are in that location.

What needs to happen

Standardised secure data exchange within and between networks

The main requirements that would improve advanced business Wi-Fi would be the network to exchange configuration and instrumentation data in XML files that are defined by the industry for this application.

Rydges Melbourne

Hotels can also benefit from an open-frame managed wireless network so that it is easier for businesses to securely “extend” their networks to these places when they organise events or lodge employees at these facilities

As well, the established secure-data-interchange standards need to come in to play for exchanging data between the devices in a managed Wi-Fi network and between managed Wi-FI networks. For inter-network access, the ability to implement VLAN connections via Ethernet, xDSL or fibre-optic setups using the same physical link as an Internet service link can be investigated for intra-building setups while manufacturers need to research simple-yet-secure VPN setup procedures for setups that traverse multiple buildings and logical networks. This also can appeal to convention / exhibition facilities and hotels which businesses make use of very frequently to host their events or lodge employees who are attending business events.

The secure-data interchange could be based on SSL standards for data-in-transit encryption while a set of XML data schemas and filetypes can be used for defining the data that is transferred.

Similarly, a system of trust needs to be established to permit exchange of data between networks especially where inter-network instrumentation is involved. It also includes determining an effective “range of influence” for managing Wi-Fi networks from outside the logical network. This could be based on a “hop-count” or similar mechanism for inter-network data exchange and may require that a high-density or multiple-occupancy development be equipped with its own network electronics that covers all services in that development.

Shared network discovery

In the case of high-density or multiple-occupancy developments which have common areas, there needs to be a way to discover the existence of configurable common-area wireless networks that cover these areas. Once such a network is discovered by a building occupant’s network, it could then be feasible for the occupant to establish or configure an extension network to cover the communal area.

This would primarily be about a “publish-and-subscribe” arrangement where the building’s management or businesses who want to offer fellow occupants use of their Wi-Fi networks can share the data about these networks on a development-wide basis while the occupants can discover the communal networks they can benefit from when they configure their network equipment.

To make it work effectively as far as the end-user is concerned, it may involve knowledge of a particular Internet-based URL which may carry the data for a particular communal network or a particular development with many communal networks. A “hop-count” discovery protocol may also have to be investigated for automatic development-wide discovery of these networks.

Conclusion

So it seems like that there needs to be a lot of work to make the advanced Wi-Fi wireless network earn its keep amongst a large user base rather than just a sole-occupied corporate office.

Update (1 December 2016): A reference to “neutral-host” Wi-Fi networks which are a single Wi-Fi infrastructure set up at the order of a venue, but is set up to provide a logical-network link to other networks like business-partners’ / occupants’ own networks or public-access Wi-Fi networks.

Assistance Journal–Dealing with a laptop’s Wi-Fi that failed after a Windows 10 upgrade

Lenovo Yoga 2 Pro convertible notebook at Phamish St Kilda

If you find that your computer doesn’t work as it should after an operating-system upgrade, check for newer device drivers from the system’s manufacturer

I had become part of a “men’s shed” community which encourages men to get together and engage in meaningful activities while being a chance for them to open up to each other easily. Here, it became a point where I could “put my skills on the table” and one of the men came to me about an underperforming laptop.

After I had gone through and removed some bloatware and updated the display-card driver on that laptop, the man approached me about this same notebook not connecting to his home network’s Wi-Fi segment since he upgraded it to Windows 10 as part of Microsoft’s free-upgrade program. I had noticed that it could connect to other Wi-Fi networks including the community’s own Wi-Fi network but he mentioned that it wouldn’t list his home network’s ESSID at all.

Subsequently I came around to his home to see the problem for myself and noticed that my Android phone could see the home network’s SSID but not this laptop. I used Windows Device Manager, part of the Windows operating system, to identify what kind of Wi-Fi adaptor was being used in that laptop and had previously researched this problem as something that could be driver-related.

Windows 10 Device Manager

Device Manager – a catalogue of all of the hardware in your computer

After that, I had hunted down a newer device driver for the Wi-Fi adaptor from the computer manufacturer’s Website and downloaded it to the computer. Then I ran the updated driver’s installation program and, after this update was performed and the computer restarted, Windows 10 properly listed the home network’s Wi-FI ESSID. I selected that SSID then used the WPS “push-to-connect” function to fully connect the laptop to the home network and it worked properly.

I even completed an Internet-connection “acid test” of having the client load a social-network session and check that it reflected the latest activity. By loading a site that is frequently updated with changing information, it avoids the Web browser loading material held in its cache which can be common with a site that doesn’t change frequently which makes me think that the Internet connection is working properly.

If you find that something like your computer’s Wi-Fi functionality misbehaves after an operating system upgrade, identify the kind of device performing the function using Windows Device Manager or a similar tool. Then track down the latest driver software from the computer’s, adaptor’s or chipset’s manufacturer and install that software. Typically this can fix the problem once and for all or make the hardware work better with the operating system.

How to effectively establish that Wi-Fi-based mobile network

Brother PocketJet PJ-773 Wireless Mobile Thermal Printer

Brother PocketJet PJ-773 Wi-Fi mobile printer – one of the mobile peripheral devices pitched to smartphone and tablet users

A major trend that has become strong over the last few years is the arrival of mobile network devices that connect to each other and to client computer devices via Wi-Fi wireless networking technology.

These are represented in the form of:

  • mobile network-attached-storage devices
  • mobile printers
  • wireless speakers, and
  • mobile broadcast-LAN tuners that work with terrestrial or satellite broadcast systems,
Network setup for mobile NAS and smartphone

Network setup for Wi-Fi-based mobile peripheral devices

What is common about all of these devices, and is treated as a key marketing feature by their vendors, is that they can be set up to be their own access point with their own DHCP server as well as being client devices to existing wireless networks. Some of these devices like most mobile NAS devices are able to work effectively as bridges or routers between an existing wireless network and the network that they create.

This may work well if you are just using the one mobile peripheral device with your mobile client devices but may not work well when you intend to run two or more mobile peripheral devices. Here, you will end up switching between different wireless networks just to benefit from the different mobile peripheral devices.

Mobile NAS as bridge setup

Wireless NAS as a bridge between mobile client devices and another Internet-providing network

But you may want to run one or more of these wireless mobile devices together to serve multiple laptops, tablets or smartphones. Situations that may come about that will call for these setups would be where you are using a mobile NAS and, perhaps, a camera that has Wi-Fi functionality or one of the new Wi-Fi-capable mobile printers. This will call for you to create a proper mobile wireless network for all of these devices.

Use a router-class device as the main device

Here, you would have to run one wireless network device as a DHCP server and “master” access point and this function can be best served by a router-class device.

"Mi-Fi" portable wireless router

A typical “Mi-Fi” portable wireless router for a mobile-broadband service

The most common examples of devices of this class that apply to “on-the-road” use are the “Mi-Fi” mobile routers that work with a mobile broadband service or one of the travel routers pitched to work with a hotel’s wired Internet service. Some mobile NAS devices may also do this wireless-bridging functionality in an adept manner and could be the hub of your “travel network”. Similarly, one of the mobile-broadband wireless routers being integrated in to some new cars by the likes of BMW and Chrysler may also answer these needs.

You may think of using your smartphone’s Wi-Fi mobile-broadband-router functionality but this may encumber your smartphone for what you want to really use it for.

Some highly-sophisticated “Mi-Fi” and travel-router devices may also expose an Ethernet connection for LAN use, perhaps through an optional extended-functionality dock. This can come in handy if you want to increase your coverage area with another wireless access point or want to use devices like games consoles with your mobile network.

You may find that you don’t need to run the Internet connection on the Mi-Fi or travel router if you are simply establishing a link between multiple mobile peripheral devices and client devices and aren’t reliant on Internet functionality for their operation. Similarly, by having your mobile devices working this way, you avoid the need to authenticate with a Wi-Fi hotspot that implements Web-based authentication to do something like gain access to your mobile NAS’s data from your iPad.

Set up known wireless network parameters

Mobile network wiht "Mi-Fi" router and 2 Wi-Fi-capable mobile peripheral devices

Mobile wireless network for two or more mobile devices and mobile client devices – uses a router-class device like a “Mi-Fi” router

When you set up your “Mi-Fi” or travel router, you make this device the hub of your mobile network and have every device “point” to this device’s local-network by associating with its SSID (wireless network name) and security parameters.

Most of the mobile network devices that work on an “open-frame” approach can be quickly associated to this “mobile hub” thanks to WPS-based push-button setup. For devices that don’t support this quick setup mode like most Apple devices, you will need to note down the “mobile hub’s” SSID and security passphrase. Some “Mi-Fi” devices that have a display may be able to show these details on their display, perhaps at the request of the user.

For that matter, a good practice would be to assign a unique SSID for your “mobile hub” device i.e. your Mi-Fi or travel router. This is important when you use these setups in campgrounds, caravan parks or hotels where many of these devices will be used at once.

All wireless devices to link with router-class device

It will also mean that the mobile NAS, mobile printer or other similar device has to work as a client device rather than as its own access point. This also applies to your computing devices like laptops, tablets and smartphones which also associate with the “mobile hub” device.

When positioning your mobile-network devices, make sure that they are in the range of your “mobile network hub” device i.e. the Mi-Fi or the travel router. All the wireless traffic that goes between these devices will pass through the “mobile network hub” device rather than between the devices themselves.

You may find that if you want to avoid draining your “Mi-Fi” router’s battery too quickly, it may be a good idea to have it run from a USB charger that runs from house current or your vehicle’s cigar-lighter socket. Similarly, a high-capacity USB power-pack can also earn its keep with these devices if you are away from power.

What I stand for when reviewing or researching mobile devices

When I review any device for this Website that is capable of being its own wireless network such as a mobile NAS or mobile printer, I test the device with my home network’s Wi-Fi wireless segment as if it is a client device. This is so I am sure they can work in this kind of setup as well as the highly-promoted “own access point” setup. As well, as part of researching a mobile device that uses Wi-Fi wireless technology as part of its link with client computer devices, I verify that it can work as part of an existing wireless-network segment as well as being its own segment.

Similarly, when I research a mobile router-class device like a Mi-Fi or travel router, I would expect the device to support WPS single-push connectivity along with other essential Wi-Fi connectivity and security standards. Similarly, such a device would have to be easy to configure including setting up the SSID and passphrase. As well, the Mi-FI device can’t be very thirsty with its battery if the goal is to have it as a “hub” device.

Conclusion

Once you are able to set up a mobile multi-device network, you can then be able to use it to store or print data while you are “on the road” without needing to constantly switch networks for each different task.

You may consider this as being of value to, for example, achieve a quieter house by having your teenagers playing their video games in the converted garage; bringing Netflix and similar services to the man-cave or just simply allowing whoever is sleeping in the guest-house to have access to the Internet.

Europeans will benefit from the fact that one right-sized satellite dish could cover your property’s satellite-TV needs including the ability to watch from that granny flat thanks to SAT>IP technology that exploits your home network as a satellite-antenna link.

This will provide what I have been talking about as a single diagram that you can understand.

Another router answers the needs for a secure home network

eero: A Mesh WiFi Router Built for Security (Product Review) | Krebs On Security

My Comments

A common issue raised in relation to home-network routers is that they aren’t really designed for security. It applies more to the equipment that is sold through the popular retail locations like the electronics chains.

This is due to issues like firmware that isn’t always kept up to date along with an insecure “out-of-box” management-console login experience. The latter situation manifests typically in the form of a default username and password that is common across a product range rather than unique to each device.

The eero router which is effectively a Wi-Fi mesh system has answered these issues courtesy of the following: firmware that is updated automatically and a secure-setup routine based around an enabling code sent to your phone. The former method has been practised by AVM with their latest firmware for the Fritz!Box routers with these devices automatically updating. The latter method has been practised through the use of a mobile-platform app where you enter your name, email address and mobile phone number. This requires you to receive a one-time password from your smartphone by SMS. You enter this to the mobile app before you determine your home network’s ESSID and passphrase.

This kind of login experience for the management Web page could be very similar to a well-bred two-factor authentication routine that comes in to play for some online services whenever you add another device or, in some cases, as you log in. Here, the FIDO U2F standard or support for Google Authenticator could be implemented in a router to permit secure login to the management page.

As for Wi-FI implementation, this router implements a proprietary mesh technology with each extender implementing separate radio transceivers for both the backhaul link and the client-side link. This allows for full bandwidth to be served to the Wi-Fi client devices. Each router device also has two Ethernet ports with one of those being configured for WAN (Internet) connection. Personally, I would like to see both ports switch to LAN mode on an eero router if it is serving as a repeater. This would earn its place with video peripherals, printers or desktop computers.

What I see of this is a step in the right direction for improved security for small networks and other manufacturers could learn from eero and AVM in working on a secure setup routine along with automatically-updated firmware.

HomePlug AV500–earns its place in connecting that man-cave to the house

Cable TV in the man-cave

He has his cable TV and download-to-view in the man-cave!

Most of you may have seen me incite the use of HomePlug powerline-network technologies as a viable option for multiple-building home network situations like linking that granny-flat, garage or barn to the Internet service coming in to the main house but may have doubts about whether I have seen it work for myself. Now I have set up such a network and seen it work for myself.

Last Sunday, I had visited some friends of mine who had just moved to a new house. This outer-suburban house had come with a detached garage where some of the space was purposed as a “man-cave” by the man of the house and he even had cable TV installed out to this location.

But the cable-TV service was augmented with a “download-to-view” movie-rental service which depended on the set-top box, which was a PVR, being connected to the Internet. The main set-top box in the house was already connected to the Internet and the home network via a HomePlug AV500 powerline-network segment using HomePlug adaptors supplied by the cable-TV provider. But the man of the house, who is IT-savvy, had a pair of “homeplugs” compliant to the same HomePlug AV500 standard as the existing segment.

HomePlug link between house and garage

What this is all about

Here, I integrated one of the “homeplugs” in to this segment using SimpleConnect push-button pairing to make sure it works as part of the segment. Then I took this adaptor to the “man-cave” garage and connected it to the set-top box there. This setup worked reliably and promptly with the pay-TV provider’s “download-to-view” movie-rental service by permitting the download of two standard episodes of an American TV series.

This setup underscored the idea of the HomePlug technologies working as part of a multi-building home network. The requirement for this to work properly is that both main building and the outbuilding have to be on the same electrical service i.e. behind the same electric meter. As well, they will work properly where the buildings are located relatively close which may be around 150 metres (164 yards), typically represented by a suburban block or a cluster of buildings on a country property located close together.
