Source : XLR8yourMac A relatively minor bug affects the 2.0.1 update of the Apple TV. With this firmware, connections with the Airport N configured to use the 5 GHz frequency no longer work when using the option WIDE CHANNEL.
A work around to this problem is either to use the 2.4 GHz band or to disable the WIDE BAND.
We will take this opportunity to say a few words about the little used 5 GHz option and also the WIDE BAND option.
The band of 5 GHz is less used than the usual 2.4 GHz, but it is very useful downtown if you are surrounded by many wi-fi networks.
The WIDE BAND option allows the base station to use a bigger bandwidth. This only works with the 5 GHz band since it can cause perturbations to neighbouring networks. However if this is not a problem for you, you can reach the maximum rate for wi-fi N of 300 Mbits/s compared to the maximum of 130 Mbits/s with the 2.4 MHz band.
