I have 2 WIFI's and it connects to the 2nd one but when I try to connect to the first it says can not join wifi. I restarted my router and it connected then but within an hour if it disconnects it won't let me back on.
16.1.1 I'm not sure if it's my phone or something is wrong with my WiFiWhich version of iOS and phone?
16.1.1 was supposed to fix some of this I think.
When I try to join my main wifi it just says can not join this networkHmm I was having it occasionally on earlier iOS versions.
Haven't been noticing it lately.
Reset Network Settings
you still have the problem?I have this problem myself and this was on iOS 15. I restarted my iPhone 13 mini but this didn't fix the problem. I am upgrading the iPhone 13 mini to iOS 16 right now but it's a 4 hour download. I think that I've had this problem since the iPhone 13 mini was new. I have the same problem on my iPad mini 5.
I do not have this problem on my iPhone 7+ which is running iOS 15.7.1. I may have this problem on the 2021 MacBook Pro as well. My secondary router is strong enough so that it is a nuisance but I can live with it. I suppose that it's possible that it is a Router setting or an iPhone or iPad setting but it would be nice to get this resolved.
I have also tried deleting the WiFi entry and re-entering it.
