All of our Rokus keep losing connection to WiFi. We're able to stream from our phones and our smart TV without any issues. Since we only have one smart TV we need help please!
Some Roku devices -- commonly the Express -- only support 802.11 b/g/n 2.4 GHz band connectivity. Some ISPs (Comcast/Xfinity as well as some others) have changed their WiFi settings to g/n, which breaks Roku connectivity. So check your model number at Settings > System > About

I have Xfinity and a Roku Express. They say problem is Roku, Roku says problem is carrier. Every other WiFi device in my house works. Do I need a moe advanced Roku ? Not willing to shell out for another failure. Thanks for the help.
There are some router setting issues that can prevent establishing Roku wifi connections. And to make matters worse, some of them can be caused by recently-reported router updates. These have primarily been reported with routers supplied by internet providers (Comcast/xfinity, Cox, and AT&T so far), but it's possible they could also occur with other internet providers or user-owned routers that have received similar updates.
If you need to make configuration changes on equipment supplied by your internet provider but you have no access to its settings, you may need to request your internet provider to make the changes for you.
If your problem was not caused by any of the above, often a restart of the router (even if other devices are still connecting) followed by a restart of the Roku will allow the connection to be reestablished. Depending on your Roku model and Roku version number you'll find the "System restart" option under either "Settings > System > Power" or "Settings > System", or if more convenient you can just remove the Roku's power for a few seconds and let it restart.
The problem is a base mode Roku Express is only a single band device. It only works on the 2.4. wireless network. Your XFinity modem needs to be on b,g,n of the 2.4 network. More advanced Roku models are dual band so they will connect no matter what
