How to solve WiFi function failure

Not long ago, a string of Wi Fi names named "% p% s% s% s% n" caused iPhone The security vulnerability event of the complete failure of Wi Fi function of iPad and iPad has attracted the attention of netizens around the world. However, just two weeks after the Wi Fi vulnerability was discovered, someone found a new similar problem.  

Now, if your iPhone joins the Wi Fi network named "% secretclub% power", the device will be completely unable to use Wi Fi functions and related functions (such as AirDrop), even after the iPhone restarts.

IPhone Wi Fi function fails

The previous problem depends on that iPhone encountered a network name with an SSID of "% p% s% s% s% n", and the user tried to connect to it; However, this error can be fixed by restoring the network settings in the Settings app. However, the new problem this time seems more serious, because once your iPhone joins a malicious public Wi Fi hotspot with the poisoned name, it can no longer be repaired by restoring the network settings.

At present, the underlying problem of iPhone Wi Fi function failure is related to "% secretclub% power" and "% p% s% s% s% n" using string format encoding error somewhere in the underlying iOS network stack. What's more, it seems that there are more malicious inducement network names using the '% s','% p 'and'% n 'character sequences that have been used by some people. This will pose a security and privacy threat to all iOS users, so we must pay attention to the big housework.

New Wi Fi security vulnerabilities found

From the perspective of individual users, the best security precaution is to avoid connecting to Wi Fi networks with [% symbol] in the Wi Fi name; Then please wait for the next IOS system Updated, Apple will fix these system vulnerabilities caused by underlying coding problems.

If your iPhone is unfortunately experiencing the above similar problems because it is connected to a public hotspot, you can try to go to General ->Restore ->Restore network settings, This will reset all saved Wi Fi networks on iPhone (as well as other network settings such as cellular settings and VPN), thereby deleting the malicious network name. If this operation still fails to solve the problem, I'm afraid the only thing you can do is to contact Apple after-sales personnel to return to the factory for repair.

Finally, I would like to remind you again that you must be careful when connecting to public hotspots outdoors. If there is a Wi Fi network containing the% symbol, you must not join it; In addition, the wireless LAN of iPhone will automatically detect the security of the Wi Fi name, and give a prompt below its name. If "Low security" is displayed, you should also carefully join the network.
