iPhone XR WiFi won't connect
Hi. I have a pretty weird problem with the wifi on my iPhone XR. I'm currently using iOS version 15.3. My iPhone won't connect to any wifi. Here are the details of the problem:
- When I'm trying to connect to a wifi SSID, a pop-up unable to connect appears.
- Sometimes it shows "unable to join the network" "this network is operating on Wi-Fi channels in use by several other nearby networks."
- I've tried connecting it to other access points, including a personal hotspot from another iPhone. The error remains the same.
- I've tried restarting my iPhone, including resetting network settings
- I've tried changing the wifi frequency, even trying all the 12 2,4ghz channels
- I've tried restarting my access point router, even
- I have reset my iPhone via mac with ipsw
- I've tried to do a factory reset on my access point
But strangely, the iPhone can be used as a portable hotspot. This indicates that there is nothing wrong with the hardware. Then why can this happen?
