Wi-Fi: Unable to connect to an 802.11n Wi-Fi network
Apple TV (2nd generation), iPad, iPhone, iPod touch
Apple products may be unable to connect to 802.11n Wi-Fi networks if WMM (Wireless Multimedia) is disabled.
This applies only to third-party routers. Apple AirPort products do not have a setting to enable or disable WMM.
WMM must be enabled for devices to connect. Disabling WMM on your wireless router can prevent the following Apple products from connecting to an 802.11n Wi-Fi network:
- iPod touch
- Apple TV
If you are unable to connect to an 802.11n Wi-Fi network on any of these devices, check to ensure that WMM is enabled and configured correctly on your wireless router. If you require additional assistance, please contact your router manufacturer.
