UWNet - Device Incompatibility List
A list of devices that will not function correctly on UWNet.
UWNet is a public WiFi network. As with any public WiFi network, some devices that utilize specific features on a WiFi network will not work on UWNet. Specifically, UWNet blocks 'IP Multicast', this will cause some devices that utilize IP Multicast to not be able to connect at all, while others are able to maintain connection with limited functionality. Although some devices may be able to maintain connectivity, some features may not work while others will not work correctly or at all..
There following two lists differ as some devices will not work under any circumstances, while the second list contains devices that may still connect for some features while other features do not work.
Known Incompatible Devices
Some SmartTVs, especially those with a Cast feature.
Note: It is hard to predict which specific models will connect due to the abundance of TV models. If unsure, ask the manufacturer if the device has 'IP Multicast'. Some Smart TVs will connect and just have limited Cast features, while others will not connect to UWNet at all.
