‘Unable to join network’ Wi-Fi error in iOS 15
I have an error on my iPhone X, which says exactly "This network is operating on Wi-Fi channels in use by several other nearby networks. Restarting the router may allow it to automatically chose the best channel to use, and may resolve this problem.".
The iPhone X refuses to connect with such an error, when Macbook, iPhone 13, and Samsung are working fine.
I live in the apartment building, and the network is provided by a service company. I don't have any access to a Wi-Fi router. I can't reboot it, can't choose any 'clean' channels, and everything else that is advised by different forum members. So won't do the service company, because no one else has this issue.
- iOS version 15.4.1 (Recently updated)
- Restarted the phone, tried the airplane mode and turning off the Wi-Fi for several times. No effect.
What should I do?
