BT have rung as I wasn't happy with the reply I had. They are saying that if it was an issue with my mobile then it wouldn't detect the other networks I connect to. Have suggested I back up and restore and reset network settings and then I'll have to re enter all the WiFi/password etc and it should allow me to connect in work. Will see when I go back in Wednesday. Does this sound like a plan to you?
Reset my networks, looking good but no cigar, searching for network. As soon as I clicked on WiFi it found the outfit name to connect but nothing even after resetting. Totally gobsmacked, BT are saying it's the router at work as I have no issues connecting at home or on mobile data. So disappointed
