I've set up the RE450 fine and it worked great when first connecting to the extender SSID - however, once I changed network to my main SSID then tried to switch back to the extender, it fails to connect. On Android I get the error "can't obtain IP" and on iPhone it says "no Internet connection".
The booster has all the LEDs on full and is functioning fine. I'm certain it has nothing to do with the location as it connected fine first time.
Any help with this would be much appreciated!
