Apple TV 2.0.1 woes blamed on 5GHz wireless issue

A number of Apple TV users are reporting wireless connection issues that appear to be related to 5GHz 802.11n networks following the installation of the 2.0.1 update. User reports indicate that after installing the 2.0.1 software, the Apple TV has trouble staying connected to some wireless networks, repeatedly dropping its connection after a short time. According to an Apple support discussion thread, the problem seems to be related to some 5GHz 802.11n networks; switching to a 2.4GHz network or simply turning off the “Use wide channels” option of Apple’s Airport Extreme Base Station appears to alleviate the problem.

Interestingly, however, I should note for the record that I am running an AEBS (original 100Mbps version) in 5GHz-only mode, with “Use wide channels” enabled, and am not having any issues with either of my 2.0.1 Apple TV units, both of which have been serving up content both synced and streamed pretty much all weekend.

I have experienced this.  switching to 2.4GHz did allow for constant streaming, however I did not try switching from the “Use Wide Channels” option.

I can’t run the update.  The Apple TV reports there is an update available, but if I try to download the update, it reports that it cannot be downloaded at this time.  Suppose they are working to resolve the issues.

There is not such thing as “802.11n” There’s a working group, which hopes to pruduce such a standard, but none yet exists.

If someone is running something saying it is 802.11n, and something else breaks, it’s correct to say that the liars who are claiming 802.11n are at fault. That includes Apple’s Airport.

IEEE 802.11 is a set of standards for wireless local area network (WLAN) computer communication, developed by the IEEE LAN/MAN Standards Committee (IEEE 802) in the 5 GHz and 2.4 GHz public spectrum bands.

The 802.11 family includes over-the-air modulation techniques that use the same basic protocol. The most popular are those defined by the 802.11b and 802.11g protocols, and are amendments to the original standard. 802.11a was the first wireless networking standard, but 802.11b was the first widely accepted one, followed by 802.11g and 802.11n. Security was originally purposefully weak due to export requirements of some governments,[1] and was later enhanced via the 802.11i amendment after governmental and legislative changes. 802.11n is a new multi-streaming modulation technique that is still under draft development, but products based on its proprietary pre-draft versions are being sold.

802.11n does not operate at 5 GHz.  It operated at 2.4 GHz like b and g.  I just takes up more spectrum so you have even less chellels to work with.

802.11a operates at 5 Ghz, and faces much less interference issues than 802.11b/g/n.  I use 802.11a for my computers and a parallel 802.11g network for devices that do not support a, such as the Roku Soundbridge, nintendo Wii, etc.
