This weekend, a new iOS bug was highlighted by security researcher Carl Schou. The latter testified that by trying to join a Wi-Fi network with a certain SSID (network name), this had the effect of making the Wi-Fi of the iOS device completely inoperable, even when joining another Wi-Fi network. -Fi afterwards.
After joining my personal WiFi with the SSID “%p%s%s%s%s%n”, my iPhone permanently disabled it’s WiFi functionality. Neither rebooting nor changing SSID fixes it :~)pic.twitter.com/2eue90JFu3

Until Apple corrects the situation, there are different ways to avoid seeing Wi-Fi malfunction like this.
It actually appears that the “%” sign in the Wi-Fi network SSID is causing the problem. Therefore, for the moment, we advise you to avoid joining any Wi-Fi network whose name begins with “%”, and/or whose name contains one or more “%” signs. At the same time, avoid naming the Wi-Fi network of your internet box with very special characters, including “%”. Reserve characters such as “%”, question mark or similar signs for the Wi-Fi password in question.
Finally, if you have ever tried to join a Wi-Fi network causing the Wi-Fi of the iOS device to malfunction, here is how to get out of the situation:
- Go to the appSettings, sectionGeneral
- Then go toReset, to pressReset network settings
- Confirm the operation
The iPhone should restart automatically, after which everything should be back to normal.
