A security researcher, Carl Schou, has found that certain Wi-Fi networks with the percent symbol (%) in their names can disable Wi-Fi on iPhones and other iOS devices.
if an iPhone comes within range of a network named %secretclub%power, the device won’t be able to use Wi-Fi or any related features, and even after resetting network settings, the bug may continue to render Wi-Fi on the device unusable, Carl Schow Tweeted.
You can permanently disable any iOS device's WiFI by hosting a public WiFi named %secretclub%power

Resetting network settings is not guaranteed to restore functionality.#infosec #0day
The bug can likely be avoided by not connecting to Wi-Fi networks with percent symbols in their names.
