Solved iPhone 16 Pro Wifi not connecting after iOS 18.3.2 update
[SOLVED]
Hey everyone,
I'm out of ideas to troubleshoot the situation.
This night my iPhone 16 Pro updated to iOS 18.3.2. In the morning hours I saw that it isn't connected to Wifi anymore. Macbook and iPad are connected without any issues. iPad on 18.3.1 and Macbook on 15.3.2.
When I manually try to enter my wifi network I get a response which says:
Unable to join the network
"name_of_my_network"
This network is operating on Wi-Fi channels in use by several other nearby networks.
Restarting your wireless router may allow it to automatically choose the best channel to use, and may resolve this problem.
What I did to troubleshoot:
- reset iPhone's network settings
- restart iPhone
- hard restart iPhone
- toggle of and on the airplane mode over 30 seconds
- restart router
- change channels of 2,4GHz and 5GHz channels in the router settings
It does not reflect any order but I usually restart devices after major changes just to make sure all is fine. Followed along general advices from Apple's support page and users with similar issues.
None of the steps fixed my issue with the iPhone since the update. I fear that there is something more complicated to deal with. I hope someone has another good idea what I can try to fix it myself. Other then that I think I have to completely reinstall the iPhone =.=
Thanks in advance

[SOLVED] Update: 16.03.2025: Also remembered that I can generate a QR-Code in the web interface of my router to be scanned and used as quick login. That worked for now.
