Chromecast or Apple TV within a public-access Wi-Fi network

Chromecast and similar devices are being used as an alternative to smart TVs

How you can use a Chromecast or Apple TV in that hotel room

There are situations where you may want to use a device like a Chromecast, Apple TV box or a network printer in a place like a hotel that has that headline public-access Wi-Fi network facility. Or you may want to make use of a portable Internet radio to listen to that Internet-hosted radio station at the worksite you are working at which has a public-access Wi-Fi network.

But you will find it difficult to use these kinds of devices on these networks for many reasons.

One of these is that if a public-access Wi-Fi network is properly setup, each device that is on the network is to be logically isolated so that other devices on that network can’t discover your devices. This is more to assure user privacy and data security for all network users.

But this will interfere with arrangements where you need to discover another device that you own that is on the network in order to use it, such as to “cast” media to a Chromecast or Apple TV. It can also interfere with file sharing between two computers or the use of portable NAS devices.

As well, some of these networks are set up with a Web-based captive portal or implement Wi-Fi PassPoint / Hotspot 2.0 or other authentication approaches. This is even if it is about assenting to the terms and conditions of service for use of the public-access Wi-Fi network. Here, these kinds of login experiences don’t work at all with devices that have a limited user interface like a small display or a user interface based around a D-pad. In a lot of cases, you will deal with devices that don’t even have a Web browser at all to work with these captive portals.

I previously covered Wi-Fi mobile networks and how they work. This included the use of travel routers or Mi-Fi devices, or NAS and similar devices that support “Wi-Fi to Wi-Fi routing”.

Travel Routers and portable NAS devices

Mobile NAS as bridge setup

Wireless NAS as a bridge between mobile client devices and another Internet-providing network. This is a similar setup for travel routers that support “Wi-Fi to Wi-Fi” operation.

One approach is to use a travel router or Wi-Fi-capable portable NAS that supports “Wi-Fi to Wi-Fi routing”. This means that the device connects to the public access network while creating its own Wi-Fi network, acting as a router. With Wi-Fi-capable portable NAS devices, you have to enable this function through something like enabling “Share Wi-Fi Connection”. You have to set the NAS so that the data that it has is not shared to the Wi-Fi network it is connected to, something you do when you set up “secure” or “private” operation.

Newer multimedia-ready hotel-room networks

Be also aware that there is an increasing number of network solutions being pitched to hotels and similar lodging establishments that create small home-network-grade Wi-Fi networks unique to each room or apartment. Some companies are even pitching this as part of their public-access Wi-Fi solution or building-wide network / Internet solution for residential or accommodation places like hotels or build-to-rent apartment buildings.

This is achieved through a distinct room-specific network served by a router installed in the room or a VLAN specific to a room or account and operates for the user’s tenure that works like a small home network.

These setups may also be to support a TV or audio setup enabled for Google Chromecast, Apple AirPlay, DLNA, Spotify Connect or other common home-network media protocols. The TV or audio setup is something that a hotelier would like to provide as an amenity to their “switched-on” guests who make use of online services and smartphones for their multimedia consumption. Such networks will typically have a “small-network-standard” Wi-Fi network covering your room or suite and will have an SSID network name and password peculiar to that network.

Most likely, if you do bring along your equipment and have it work with the room-specific multimedia network, you will be able to discover it as long as your computer or mobile devices are linked to that particular network. This could mean that your Spotify-Connect-capable wireless speaker could work with Spotify on your smartphone like it does at home if all these devices are connected to the room-specific network.

You may find that the hotel you are staying in may be set up this way and there could be printed material in your room about this kind of network existing and how to “get on board”. Typically this requires you to connect your smartphone and your devices to the room-specific network once you have activated that network connection.

Your regular laptop computer as a travel router

Your laptop that runs Windows 10 or MacOS 13 Ventura or newer operating systems also offers this same functionality

Laptops that run Windows 10 or MacOS 13 Ventura onwards can offer this same functionality natively. This is infact an approach that I used to run my Chromecast with Google Play as an audio-video output device for my Samsung Galaxy A52s smartphone at the Elsinor Motor Lodge in order to play my music through the motel room’s TV speakers.

Windows 10 onwards

Windows 11 Settings - Network And Internet - Mobile Hotspot option highlighted

Enable the Mobile Hotspot option in Windows 10 or 11 so your laptop becomes a travel router or mobile hotspot

  1. Select “Settings” which is the gear-shaped icon to open the Settings menu
  2. Select “Network and Internet” on the left of the Settings screen to open the Network and Internet window.
  3. Enable Mobile Hotspot whereupon you will see the setup for sharing your computer’s Wi-Fi connection.
  4. To see your hotspot properties, click the “ > “ next to the “Enable Mobile Hotspot” toggle. Note down the Network Properties on this screen which correspond to the SSID (Network Name) and Password for the Wi-Fi hotspot created by your Windows computer.

    These are the settings you need to go over to make sure your mobile hotspot works. The network details refer to what your devices need to be connected to.

MacOS 13 Ventura onwards

  1. Click the Apple icon at the top left of the screen and select “System Settings
  2. Select “General” then select “Sharing
  3. Look for “Internet Sharing” and click the i nearby that option
  4. Select the network connection that has the Internet service – this could be Wi-Fi or Thunderbolt Bridge.
  5. Select the network connection the other devices will connect to using the “To Computers Using”, which will be Wi-Fi
  6. You then have the option to create a Network Name (SSID) and Password for the hotspot network. Note down the SSID and Password you created for the hotspot,
  7. Once everything looks OK, click Done and toggle Internet Sharing on.
  8. Click Start in the pop-up message to confirm Internet Sharing.

Setting up your devices

Then, set up your devices like your network media player or network printer to link to the hotspot network you created in the above steps. Most network media devices will require you to go through the “manual Wi-Fi setup” process with some devices, especially speakers, requiring you to link to a “setup” Wi-Fi access point integrated in the device and running a setup Website hosted by that device.

That also means that your smartphone or tablet has to connect to the hotspot network if it is to benefit from the devices that you connected to that network. This would be important for media-sharing protocols like Chromecast or DLNA, or network-printing protocols like AirPrint or Mopria.

When you are finished

If you are using Windows or MacOS as a travel router, turn off the “Mobile Hotspot” or “Internet Sharing” functionality before you pack up your equipment. This is to assure secure operation and also saves on battery power for your laptop computer. With a travel router or portable NAS, you just simply disable the network-sharing functionality when you pack the equipment up.

Remember that the settings will stay the same for your Mobile Hotspot or Internet Sharing functionality so you don’t need to connect to a new Wi-Fi network if you use the same method again. This also holds true for travel routers or portable NAS units that implement network sharing.

In the case of that multimedia-ready hotel room network, you will still have to connect your equipment including your computer or mobile devices to these networks when you set yourself up in your room. This is because the guest credentials are likely to change as a means of protecting guests’ own equipment and experience.

Are we to expect laptops to be mobile phones?

My Comments

An increasing trend we are seeing with regular desktop and laptop computers is that they are being used for voice and video telephony. Thu is being driven by messaging apps of the Skype, Facebook Messenger, WhatsApp and Viber kind being ported to desktop operating systems; along with softphone applications that provide telephony functionality being made available for these operating systems. The softphone applications, along with Skype are even legitimising this usage case with laptops in the business environment turning them in to secondary or replacement phone extensions.

Headsets like the JBL E45BT Bluetooth headset are used with laptops to make voice calls with messaging apps and soon this will happen for mobile telephony

With these setups, you can talk with the caller using the computer’s integrated or attached microphone and speakers. Or, should you want the same level of privacy associated with holding a handset up to your ear, you can talk to the caller using a wired or Bluetooth headset, of which I have reviewed many on HomeNetworking01.info.

Microsoft and others in the “open-frame” computing world are pushing along with the Always Connected PC which runs ARM RISC microarchitecture rather than the traditional Intel-based CISC kind. These ultraportable computers will also be equipped with a wireless broadband modem that is authenticated using eSIM technology.

The idea is to eventually have these computers become like a smartphone with them linked to the cellular mobile network. It is also alongside the fact that today’s smartphones are effectively pocket computers running a mobile operating system.

It could be easy to say that the Always Connected PC concept is irrelevant because one can “tether” a computer to a smartphone to have access to the mobile broadband service, whether through a USB connection or a Wi-Fi-based “hotspot” function that mobile operating systems support. Or we can simply connect our computers and phones to Wi-Fi networks including publicly-accessible networks like hotspots. For that matter, computers can also be connected to other network types like Ethernet or HomePlug AV networks.

Smartphones now are pocket computers

Let’s not forget that the GSM Association and the Wi-Fi Alliance are looking at Wi-Fi networks as a way of providing data-offload functionality. This is through mobile carriers like BT and Telstra offering FON-style community Wi-Fi networks and the Wi-Fi Alliance using Passpoint / Hotspot 2.0 as a way to provide hands-off login to public-access networks.

The Wi-Fi functionality is also being taken further in the context of smartphone-based voice telephony with the use of VoWLAN as another call-transport option for these devices. Some mobile telcos like Telstra even use this as a way to provide voice telephony continuity to their customers if they can’t reach the cellular network but can use Wi-Fi-based Internet.

The focus now is towards the concept of always-connected portable computing with a secure and consistent connectivity experience. This is being brought on through the use of 5G mobile-broadband technology and the interest in edge computing which provides support for localised data processing and storage in a cloud environment.

The eSIM is being pitched as a way to provision mobile service in an online manner, especially to vary the service to suit one’s needs or switch to a competing mobile telco. It also is placing pressure upon mobile telcos to adopt a “service-focused” approach with the idea of having multiple devices on the same mobile account and plan, ringing to the same mobile number and using the same data allowance. The goal with mobile telephony will then be to make or take a voice or video call or send and receive messages on the device that you currently are using rather than changing to a different device for that task.

Connected cars even to be another logical device for one’s mobile service account.

This concept has been driven by the Apple Watch and will be pushed on with smartwatches that have built-in mobile broadband modems. But it will be extended through other devices like smartphones, Always Connected PCs and connected vehicles. There is also the idea of implement the equivalent of a local area network across devices tied to the same service and this will be driven by the trend towards ubiquitous ambient computing.

A question that will come about is the ability to maintain multiple different services on the same physical device whether from the same telco or different telcos. This will be about maintaining separate services for business and private use. Or it could be about travellers who want to maintain a local service while at their destination along with their “home” service. This is a feature that is of relevance in countries where cross-border commuting is the norm thanks to land borders or short affordable ferry rides.

This could be addressed through support for multiple services including the ability to provision a cluster of multiple devices with the one service simultaneously. This same issue can also address the ability for us to use the conventional Internet service based around a hardwired broadband service with a Wi-Fi and / or Ethernet local network in the premises.

What I see out of this new trend is that if your computing device has mobile broadband or connection to the Internet via a local-area network, along with a speaker and microphone, it will become the one-stop computing and communications device. It doesn’t matter what shape or size it is in, being a smartphone, laptop or whatever. As well, the right-sized computing device will serve your computing and communications needs as you see fit.

An Internet-connected laptop could replace the link van for location broadcasting

IP Studio whitepaper

My Comments

If you watch news, sports, live concerts or similar content on TV, you will be seeing location broadcasting at work as they bring that footage to your screen.

Typically, a location broadcast that any TV studio does either required the use of video recordings that were transported to the studio before broadcast. Or they relied on a “link truck” which is a vehicle equipped with an antenna that beamed the location signal back to the studio using a microwave link if the idea is to allow the studio access to real-time vision. Some regular venues that are regular sources of content may implement a wired connection facilitated by a leased line between that venue and the studio.

Such setups have been limited by the amount of time required to locate the link truck and establish these radio links. This can also be limited through factors like weather or making sure of a line-of-sight connection to the studio’s link tower.

But the Internet and the size of computer technology has opened up the possibility of a laptop of the same or better calibre as the Dell Inspiron 15 7000 Gaming I recently reviewed connected to a high-bandwidth Internet connection as an alternative to the traditional location broadcast setup, especially for shows directly streamed to the Internet. The technology which is called IP Studio is part of an effort that Auntie Beeb is taking towards implementing IP technology for TV-show production. In this context, it is about being able to use a mobile wireless network to interconnect the cameras to the laptops for location broadcasting.

Here, they are using the Edinburgh Festival and Edinburgh Fringe Festival to prove a setup based around laptops that are uplinking to the Internet via the same kind of technology used for Internet service. The editing software that is being used is primarily a Web-app which works in the browser rather than a standalone app. But it could allow for the link-van approach where a laptop is used to upload the edited vision to the broadcaster’s studio to be inserted in to the program.

Once it is proven, the BBC’s IP Studio technology which is based primarily on open-source tools, could be seen as beneficial for all sorts of broadcasters who want to save money and set-up / tear-down time on and see increased flexibility with their location work. For example, news-gathering teams could be able to set up and “go live” on that breaking event or press conference with a very short lead-time.

The same technology could open up affordable location-broadcasting technology to community broadcasters and specific-event Webcasters who place importance on cost-effective setups. Even organisations who have video-editing talent in their staff or volunteer collection could see this technology appeal to them.

What this is showing is that the Internet and cost-effective computer design is making big-time broadcasting and production technology more affordable.

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

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.
