After the last update my three Roku TVs are not reading my Wi-Fi when I go to connect to the internet the Wi-Fi is working on all other items that I have in the house. So the three roku's that I have are now useless because they are not seen my Wi-Fi as an option to connect to please help. Before the update all three TVs were connected just fine to my Wi-Fi which is T-Mobile
Try turning off your router for a minute. Then allow the router to reboot and perform a Network Connection Reset on one of your RokuTVs. (Settings/System/Advanced System Settings/Network Connection Reset/Reset Connection).
Post back with the TMobile router model number and some more details.
Is your network not even coming up in the list of available networks? (any others showing, ie. neighbors). If seeing it, is it just not connecting to it?
Try using a mobile hotspot on your phone (if available). Can the RokuTV see the hotspot and connect to it?

I am also thinking it may be an unsupported DFS channel or AX setting in router but lets start simple and see what the above tests show first.
