I got this wifi problem 3 days ago on my iPhone 11 and I thought something's wrong with the hardware. Then I upgraded it to iPhone 12. Same thing!
My problem: It (my iPhone 11 or iPhone12) can intermittently connect to my mesh network (1x ASUS TUF GAMING AX4200 + 1x ASUS RT-AX57). 90% it fails! It can acquire the IP but most of the time (after waiting for tens of minutes) "Router", which is supposed to by the main router's IP, is empty; if it's not empty, then "No internet" appears under my Wifi name (with a tick indicating Wifi connection is established).
Tries:
- Disable Wifi 6 on my network
- Disable Limit Address Tracking and/or Private Wifi Address on my iPhone
- Reset my iPhone's Network settings
- Reboot my iPhone
NONE WORK!!!! The circle next to my Wifi name just turns around and around!
Apple is becoming worse and worse... So frustrated!
