220WARNING - I will NOT be held responsible for any damages the methods shown in this video may cause to yours or someone else's computer, hardware, software, and/or data, including loss of use of such devices and/or loss of data and/or loss of profits from the resulting inability to use such devices and data. Any information or program you choose to put into use from this video is done AT YOUR OWN RISK. As a precaution, I recommend backing up any irrecoverable data before using ANY of the methods shown in this video.
If your Apple iOS device (such as the 4th Generation iPod Touch 4G, 5th Generation iPod Touch 5G iPad, iPad 2, iPad 3, New iPad, iPad Mini, iPhone 3GS, iPhone 4, iPhone 4S, iPhone 5, iPhone 5S, etc) will not connect to a Wi-Fi router with wireless security enabled (such as those requiring a password, passkey or passphrase to access the network and/or those that use security measures such as wireless MAC filtering and/or WEP, WPA, or WPA2 encryption), inexplicably reporting back 'Unable to connect to ROUTER NAME' no matter how many times you ensure that the passkey that you are typing in is accurate, and even if your iOS device has all the proper credentials and permissions to access the wireless Internet and network, your device simply will not connect, then this video may present the fix or solution you need.
Essentially, for those who would prefer to read rather than watch a video: temporarily disabling security measures one at a time in your router's settings, while each time attempting to establish a Wi-Fi connection using your iOS device, eventually one or more of the security measures having been disabled SHOULD grant access to your wireless network on your iOS device. Once this initial network connection has been established on your iOS device, re-enabling all of the previously disabled security measures SHOULD permit these measures to be implemented and active all while maintaining the wireless Internet and network access previously established on your iOS device.
