I have tried to reset network, reset phone, I’ve tried airplane on and off. Nothing works. I have heard a lot of people having this issue as well. What do I do??

If your iPhone or iPad won't connect to a Wi-Fi network - Apple Support

I bought iPhone 13 at the beginning of this year every month I’ve had an issue where WiFi and Bluetooth grays out and phone loses service and turns on and off by itself they’ve repaired phone/replaced phone 4 times even sent it to apple for repair got it back the 4th time and had it for two weeks then did the same thing apple just keeps doing the same thing which won’t fix problem just sent it in again so thinking iPhone 13 is just a junk phone
