A Danish researcher has discovered that a certain Wi-Fi name can completely disable an iPhone's Wi-Fi function.

Even if the phone is rebooted, the problem still persists.

It concerns the name %p%s%s%s%s%n.

Anyone who connects to this network with an iPhone will notice that the WiFi no longer works.

It is then not possible to turn the WiFi back on.

Restarting the phone doesn't help either.

Users must reset their entire network settings in order to reconnect to a Wi-Fi network.

In this way, the specific name of the network will be cleared from the iPhone's memory.

This solves the problem.

Apple has not yet responded to the bug.

Anyone naming a public Wi-Fi network with the above name could be exploiting this error.
