@Omar Attia can you connect to other 2.4ghz wifi? Also did you tell phone to forget the old wifi?

@stressmaster Unfortunately, I only can connect to routers that support 5ghz Wi-Fi. I can't send even a hotspot to any device until I change the hotspot band to 5ghz.

It is possible the wire that is the 2.4Ghz in the phone came loose. Or the board has a chip or resistor/transistor burn out.
