I have a network made up of a WPA4220 KIT (V1.2) to which I have added two more WPA4220 extenders (V4). Until this afternoon they all worked fine, scattered across the house and all using the same SSID so users could roam around freely.

Mid afternoon the V1.2 extender from the original kit started to play up. Dropped WiFi and Internet outages.

I reset it and now it will pair to the Powerline network but I can find no way of cloning the SSID.

Pressing the WPS on the router doesn't work

Ethernet cable connection won't allow me access to settings.

I can see the extender in the TpLink Utility but there is no 'internet' buttn to allow me to access the settings.

None of the app based ulitites are compatible.

It exists as a standalone WiFi network that I can connect to independently and it works fine. I just can't get to the settings to align it to the main house SSID.

I have done all firmware updates.

Any ideas? It's driving me mad!
