Had to hard reset my roku express due to not connect to my Wi-Fi anymore after having it for almost two months. Now I can’t activate it back. I input my email and i haven’t received an email yet it’s been two hours. Serial number A210740495004768
ROKU CANNOT FIND LOCAL WIFI NETWORK Some routers (reported from Xfinity and Cox, but there may be others) have had their 2.4 GHz wifi band turned off by a router update, leaving only the 5 GHz band operational. Devices with single band wifi radios, notably Roku Express and Premiere models (but not Express 4K models) as well as many other single band devices can not even see the 5 GHz band. The solution is to reconfigure the router and turn the 2.4 GHz band back GHz. If you don't have access to your router setup you may need to have your internet provider do it.
If this problem was not caused by a router update deactivating the 2.4 GHz band, 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 or Settings > System > Power.
