I've just upgraded from a GS21 to a GS23+ but when I try to connect to my home WiFi, nothing is listed. It avoid all the standard questions, I've followed all the advice online: soft reset, network reset, safe mode, and factory reset. Even when the phone is completely new and I'm going through setup, no networks are listed.
Now to add to the mystery, ive also upgraded my wife to a GS23 and her phone is doing the same thing. Oddly though, if I start up both of our old phones (GS21 A52 respectively) they show our home network plus our neighbours networks as well.
