Hi. I have a 2020 M1 Macbook Pro A2338 that I replaced the screen on and ever since the WIFI is off and will not let me switch back on.
The WIFI worked perfectly prior to repair and now the screen and internet work well but only when wired to router.
A wiggle test with continuity meter on WIFI wires revealed a bad connection so I replaced WIFI antenna/vent. No change. I performed a hard reset(all power and battery disconnected for 30 mins) and No change.
I did notice with old antenna the WIFI icon acted like it would look for signal for a split second and give up but since replacement of antenna, it doesnt even try.
I was told its probably a logic board issue. My next step is to send it out for repair.
