Wi-Fi: Unable to connect to an 802.11n Wi-Fi network

Symptoms

Apple products may be unable to connect to 802.11n Wi-Fi networks if WMM (Wi-Fi Multimedia) is disabled.

Be sure you've reviewed connecting to wi-fi before proceeding with this article.

Resolution

Some third-party wireless routers allow you to modify the WMM setting. 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:

  • iPhone
  • iPad
  • iPod touch
  • Apple TV

If you are unable to connect to an 802.11n Wi-Fi network on any of these devices, ensure that WMM is enabled and configured correctly on your wireless router. If you require additional assistance, please contact your router manufacturer.
