@woozle Many Thanks 🙏 I now have WiFi Extention in d'house!!! I did not realise the tiny 'Join' at top right of the window was a button... I thought it just a label for that window. DOH! Mea culpa....

I have tried via WPS button, Wifi symbol flashes white then goes out... I set up the Tether app, I get to stage of entering home hub password, (CORRECTLY!!!) hit 'done' on keyboard, then page fails...
