Has it happened to anyone else? Using the blue router given by Jio. Till afternoon everything was working fine, then it disconnected on a 2.4G only phone, turns out the 2.4GHz band doesn't connect to any device now. Have tried everything, restart, reset, changed SSID/password from MyJio app and directly from router webpage. Tried multiple SSIDs simultaneously. Nothing, 2.4GHz just doesn't connect. 5GHz connects fine and internet is working normally. What do I do?
