I've had a lot of difficulty figuring out how to manually change the channel of my Airport Express. I have followed the directions posted on forums and on Apple's site: To change the channel of a 2.4 GHz network: 1. Open AirPort Utility, located in the Utilities folder in the Applications folder on a computer using Mac OS X, and in Start > All Programs > AirPort on a computer using Windows. 2. Select your base station, and then choose Manual Setup from the Base Station menu. Enter the base station password if necessary. 3. Click AirPort in the toolbar, and then click Wireless. 4. Choose a new channel from the Channel pop-up menu. The issue is that when you select wireless there is not a channel option. Under summary the channel is listed as automatic, and when you click channel it just takes you directly to the wireless section again, only to find that again there is no channel selection option. What am I doing wrong, any help would be greatly appreciated!
