Hi all, I've set up my WPA8630 extender to work in the garage - unifying all SSIDs and passwords with the router. But garage signal is very weak so looking at other options.

However, when I unplug/ unpower the extender, it seems no other devices in the house can now connect to the 5GHz router network - we are all getting 'unable to connect to this network' or 'password is incorrect'. Password definitely is correct.

But when I plug the WPA8630 extender back in to a socket in the house, normal service is resumed and the 5GHz is 'reactivated'. Devices are only connecting to the extender it would seem. Something is blocking access to the router 5GHz network, even when the extender is powered off.

Does anyone know what's going on here? I have tried 'forgetting the 5GHz network' in my iPhone and re-entering WiFi credentials but it makes no difference.

Totally stumped - any help appreaciated!
