Just a bunch of harmless letters and symbols can disable iPhone’s Wi-Fi connection. So, How to Fix the Mysterious iPhone Wifi Bug.
An abnormal iPhone Wifi Bug is disconnecting the iPhone’s Wi-Fi connection. Fortunately, if your phone is affected, it is easy to avoid and fix it, but damn it, it’s weird. In short, for some reason, if your iPhone is connected to a wifi network named “% p% s% s% s% s% n”. The device’s wifi will stop working. So don’t do that.
Security researcher Carl Shou first discovered this vulnerability and posted the discovery on Twitter. Subsequently, several other users conducted their own tests and confirmed the problem. In each case, the network name alone broke the Wi-Fi function of their iPhone and prevented them from connecting to other networks. To make matters worse, the testers found that the error persists even after restarting the affected iPhone.
Interestingly, this error does not affect other network functions, such as Bluetooth or mobile data. Connecting to the sonamed Wi-Fi network on Android has no effect; the vulnerability seems to originate from the iOS operating system or iPhone hardware. But no one currently knows why this particular SSID would disrupt the iPhone’s Wi-Fi function.
Fortunately, if your iPhone detects this problem, you can easily fix it: just go to “Settings”> “General”> “Reset” and select “Reset Network Settings.” This will delete all saved Wi-Fi connection information, so you must set up a new connection the next time you reconnect to a secure network, but it will also immediately reverse the error.
Although correcting Wi-Fi errors is simple, preventing it is more complicated.
Obviously, avoid connecting to the network or naming your home Wi-Fi “% p% s% s% s% s% n” and when you see a public Wi-Fi hotspot using that particular SSID Warn others. However, other seemingly benign network IDs can trigger the same failure. This leaves iPhone users vulnerable to malicious attacks, unaware actors and users even accidentally giving their public wifi connections a wrong name. Therefore, in general, avoid using networks with many “%” signs in their names. If you encounter errors after connecting to a public network, notify the network administrator.
If the error is fairly common, Apple will most likely release a patch to fix it. Of course, this problem cannot be repaired, even if it can, each user is responsible for protecting their equipment during this period.
