did you try connecting on different wifi networks or just yours? are the wifi networks detected? does your phone get an ip address? did you try to set your phone Mac to device's instead of random? also it could be firmware issue, which version do you use? on 12.5.4 or. 12.5.5 no issues for meMy router is not modified, i have never had a problem on any other phone or software with initial setup, only on these latest a12 roms.
