Accessing wireless Internet (Wi-Fi) through your mobile phone should be as simple as searching for a network and entering the associated password. However, there are drawbacks to consider which can make the process challenging.
A security researcher has discovered that some Wi-Fi networks with a percent (%) symbol in their names can disrupt the Internet on iPhones and other iOS devices, such as the iPad.
In a tweet posted by The Verge, Carl Shaw explains that if the iPhone is in close proximity to a network called “%secretclub% power,” for example, it won’t be able to turn on Wi-Fi or access related tools. The problem becomes even bigger because even after restoring the original settings, the error remains.
Although Apple has yet to officially react to the bug found by the investigator, 9to5 Mac says it should be possible to avoid the bug simply by escaping from these types of networks. If the devices are not connected to Wi-Fi with “%” in the name, the problem should be resolved.
You can permanently disable WiFI of any iOS device by hosting a public WiFi named %secretclub%power
Resetting network settings cannot be guaranteed to restore functionality.#Information Security # 0 day
