iPhone says wifi password incorrect when it isn't - Fix

I had this problem with an iPhone and a new wifi hub.

I solved the problem by switching off the 5 GHz channel on the wifi hub (it was on 2.4 or 5 GHz).

My speculation is that the 5GHz signal wasn't really strong enough/had too much interference to work despite the phone showing 4/5 bars of wifi (and that the iPhone is giving a bad error message).

Anyhow, it has been fine since.

Writing this because I saw that this has been an on-going problem annd searching the forums hadn't shown me a good answer.

iPhone SE, iOS 16

My iPad continuously reported the wrong Wi-Fi password, even though it was correct. After trying basic troubleshooting like resetting network settings and restarting devices, I found that changing my router’s security setting from WPA2/WPA3 Personal to just WPA2 fixed the problem. This suggests a compatibility issue with the mixed security mode.

Let me know if this solution works for anyone
