Default Bye Bye 40 MHz Mode in 2.4 GHz

Apple Airport Extreme Base Stations (and Time Capsules) at the latest firmware (V7.6.1) come OOB in "Use Wide Channels" mode.

You can't access the setting from "Airport Utility", you must use "Airport Utility 5.6", a separate download.

Is that in 2.4 GHz and 5 GHz?

Default Dunno

Doesn't seem to distinguish between them. Just sez:

Use Wide Channels
Wide channels provide higher throughput in your network, but might interfere with nearby networks.

It's under:
<Pick an Airport>
Manual Setup
Airport
Wireless
Wireless Network Options

I always disable it, I've never been asked about throughput problems, and I'm always fighting connectivity and interference problems.

I'll have to take a look at it for part 2. Thanks for the heads up.

I'll be extremely interested to know what it's actual behavior is in each mode. 8*)

Thanks!

No joy. 40 MHz mode is still disabled in 2.4 GHz even with the "Use Wide Channels" option enabled.

So it's only applicable to 5GHz?

Is it safe to assume this is only the case running certain stock firmwares and under third-party firmwares like tomato & dd-wrt the 40MHz bandwidth setting can be set and won't fall back to 20MHz?

I certainly hope none of the 3rd-party firmwares will allow "Trash Your Neighbor" mode!
