If you have an iPhone, beware of a strange wifi network with the name “% p% s% s% s% s% n”. This name causes a tiresome bug. Do not connect to this network unless you want your phone’s wifi functionality to be interrupted.
The bug was found by security researcher Carl Schou, who shared the issue on Twitter. Schou explained that after joining the “% p% s% s% s% s% n” network, his iPhone permanently disabled its wifi functionality. According to 9to5Mac, the bug also affects iPads, as well as services like AirDrop. Devices cannot connect to wifi networks even after restarting or changing hotspot SSID.
Schou did not exactly reveal how he found the bug, although this has been confirmed by other brave Twitter users who tried to connect to a wifi network with that name. MacRumors reported that wifi on android phones doesn’t seem to break when connected to the same network.
Fortunately, the bug does not appear to cause permanent damage to your Apple hardware and can be fixed. Once you’ve got over your fury and frustration, if you find yourself in this situation, sure. (Or at least that would be my reaction).
The fix is simple. You just need to reset all network settings, 9to5Mac noted. This can be done by going to Settings> General> Reset> Reset network settings. This will reset all wifi networks saved on your iPhone, thereby erasing the cursed network name from the device memory. After that, your phone should be able to connect to wifi normally again.
As to the reason for the bug, the common theory seems to be that this is an input parsing issue that makes iOS think that the characters following the percent sign are a string format specifier, referring to a variable name or a command used in coding languages. Some believe that tthis could possibly lead to memory corruption, which would result in the IOS Watchdog to eliminate the process, and in turn your wifi functionality.
Although you may not find wifi networks named “% p% s% s% s% s% n” every day, it is best to be vigilant on any network with a percent sign or in the same vein as the one. here until Apple fixes the problem in an update.
