wifi

antonín163,

Let's continue with trying some additional steps to resolve this.

Please go to Settings > Wi-Fi and tap "Forget This Network". Then try joining the network again. Be sure to verify "Auto-Join" is turned on as well.

If you continue to experience the same thing, try resetting the network settings. This resets Wi-Fi networks and passwords, cellular settings, and VPN and APN settings that you’ve used before. Make sure you have your Wi-Fi network password handy before completing this step. Go to Settings > General > Transfer or Reset [Device] > Reset > Reset Network Settings. Once this completes, test to see if the issues are resolved.

Cheers.

Hey there, and welcome to Apple Support Communities, antonín163.

We see you're having some trouble with your Wi-Fi. We've got some questions to better understand what's going on.

•Which iOS version do you have installed? You can find that by going to Settings > General > About.

•Does it connect back to Wi-Fi when you start using it again?

•Does this happen on all Wi-Fi networks?

We look forward to your responses.

antonín163,

At this point, we'd recommend using Get Support to contact Apple and work with them from this point.

Cheers.
