CAUSE

You may receive this error message if the wireless network connection supports the 802.11a standard but you are using the 802.11b or the 802.11g standard for the wireless network.

THINGS TO TRY

Configure the wireless network to use the 802.11a standard.

Note The 802.11a network uses a different frequency than the 802.11b or 802.11g networks. Therefore, if you experience performance problems with the audio or the video when you watch TV, an 802.11a wireless network may provide less interference than 802.11b or 802.11g.
