Thanks to everybody who tried to help with this

In the end I had to call out a guy who was really helpful

Factory reset had switched router to different Wi-Fi channel. Apparently there are some seven available. The PC hadn’t recognize the new one I needed some changed settings
RT @GreenPartyMolly: I’ve had to do a factory reset of my router and now my PC won’t connect to WiFi

Any tips?
