iPhone users: Do not join WiFi network named like this - your WiFi wont work after this

Written by Petteri Pyyny @ 20 Jun 2021 6:45 User comments (2)

Security expert Carl Schou has spotted an interesting bug in Apple's iPhone WiFi connectivity. Joining to a specifically named WiFi network will freeze the phone's entire WiFi connectivity - permanently.

After user joins such network, the WiFi connections freeze completely and not even rebooting the phone will fix the problem. Neither will disabling WiFi and turning it on again. Only solution is to reset all iPhone's network connections completely through iPhone's settings, which will wipe out all the stored WiFi passwords and settings.

The problem exists also in Apple iPad tablets and behaves similarly. Apple hasn't released a fix to the problem yet.

If the fix is as easy as "Reset network settings," it's not only not permanent, it's not even a big deal. That's often one of the first things you try when an iPhone has connectivity issues.

After resetting all setting

Tap Settings > General > Reset > Reset Network Settings. This also resets Wi-Fi networks and passwords, cellular settings, and VPN and APN settings that you've used before.
