I have a problem with the Wi Fi connection since 14.5 and I patiently waited for Apple to release 14.6 in the hope that they fixed this bug, but nothing has changed.When the phone is restarted, the phone connects to the Wi Fi network but does not work. Interestingly, if a friend let my hot spot work without a problem, but when it is on any Wi Fi connection to the router does not work. About an hour later he recovers and starts working. I wrote to Apple several times to tell them about the problem, in my post here other people said they had the same problem but Apple didn't seem to notice. I hope that with iOS 15 I will finally have a normally working Wi Fi Thanks Apple, innovative as always.
