Use more 'radio modes' for AirPort Extreme Base Stations Network
By default, the AirPort Utility only allows several 802.11n radio mode options as shown in this screenshot -- basically four different 802.11n modes: b/g compatible, 2.4GHz, 802.11a compatible, and 5GHz. To get four more options (b/g/a only, without n), just hold down the Option key while clicking on the Radio Mode drop-down menu in Airport Utility's Wireless tab. You should see a list of options just like this one.

This is documented in Apple's current Designing AirPort Networks PDF, but is somewhat hidden in the middle of the document as a side note! Maybe this is of help for someone trying to create an "n-less" WLAN.

Use more 'radio modes' for AirPort Extreme Base Stations

I do not get any options for n only or to specify frequency on my system. Without the option key I have only one item in the popup menu; 802.11n (802.11b/g compatible). With the option key, I have that plus, 802.11b only, 802.11g only, and 802.11b/g compatible. This is with a Time Capsule as a WDS main, and also with an Airport Express as a WDS remote.

The wireless devices on the network are an iPhone and an HP printer, both of which are b/g compatible devices; neither supports n.

That's probably because the AirPort Express doesn't support 802.11n either. AirPort Utility knows that your Extreme is in a WDS with it and won't let you unintentionally break that by changing the mode.

Excellent tip!

I must remember to keep hitting the Option key to discover these "hidden" variations for myself.

Use more 'radio modes' for AirPort Extreme Base Stations
Authored by: Panjandrum on Apr 18, '08 12:55:20PM

What I really need is a way to control which channel these puppies select in "N" only wide-band mode. I have three of them in a building, but they automatically choose the same channel and there is no way to set it manually in this mode. This confuses laptops which are put to sleep in one area and awoken in another area of the building. Even with all three stations set to minimum transmitter power, the portables will frequently fail to switch to the closer station with the better signal. I can put them in n/g compatible mode, and then select 1,6, and 11. That allows the laptops to switch transmitters much more reliably as they are moved around the building. But it also reduced performance more than I would like.

I don't suppose anyone has a solution for that little pickle?

Option-click the pop-up, no?
I see a list of eight channels, ranging from 36 to 161.

OMG this is genius. I've been trying to figure out how to get my Motorola Droid to connect to my Airport Express. My GF's Ipod Touch connects fine (of course) but my Droid would constantly connect and then drop. Turns out the Droid doesn't like N networks, at least not Apple's. However, when I went to manual setup on the airport utility, it would only give me the N options. I KNEW 'B/G only' had to be in there somewhere, or maybe Apple were just being jerks and locking those options out of the Express. Anyway, tried this on a PC (used Ctrl instead of Option) and THERE THEY WERE! Switched it to B/G only and ___BOOM___ my Droid is now getting major love from the internet.

THANK YOU!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
