UWNet - Device Incompatibility List
A list of devices that will not function correctly on UWNet.
|NOTE:The information in this document only applies to the UWNet SSID. If connection still fails in the residence halls after troubleshooting, purchasing a personal router or connecting to the wired Ethernet jack in the room will provide connectivity.|
UWNet is a public Wi-Fi network that can be accessed by anyone here at UW-Madison. As with any public Wi-Fi network, some devices that utilize specific features on that network will not work on UWNet. Specifically, UWNet blocks the "IP Multicast" feature, which will cause some devices that utilize this feature to not be able to connect at all while others are able to connect with limited functionality. This feature is common in devices such as Google Homes, Amazon Echos, and Google Chromecasts (basically, anything with a Cast feature or something similar built-in). Features other than "IP Multicast" may also cause issues and function incorrectly on UWNet.
The first list contains devices that will not work under UWNet, while the second list contains devices that partially work under UWNet (i.e. certain features will be unavailable).
NOTE: The DoIT Help Desk cannot guarantee that any device on either of these two lists will/will not work on UWNet. Devices on these lists may work in certain scenarios, for limited amounts of time, or not at all.
Known Incompatible Devices
Smart home devices such as Google Home, Amazon Echo, etc
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.
Any device that is not able to be registered using a web browser. Users with a UW Madison NetID can attempt to connect by registering the device as shown here: UWNet - Register a Device Without a Browser or Pre-registering a Device Before Arriving to Campus
Devices That May Experience Connectivity Issues
The following devices may be able to connect to UWNet and use the internet in some cases, but the features of the device may be limited (such as online gaming/voice chat).
NOTE: The NAT type of UWNet, which limits some online gaming functionality in modern game consoles such as the PlayStation 4 and Xbox One, cannot be modified due to security reasons.
Nintendo 3DS and DS
- NOTE: The Nintendo Wi-Fi Connection service, which the original Nintendo DS used to connect to Wi-Fi, has been discontinued by Nintendo and will not work in any scenario.
Any device that has a 'Cast' feature
