Glenn,

"For a one-band-at-a-time 802.11n base station, hold down the Option key and then click on Channel in step 3, and then select the channel from the pop-up menu that appears."

I have my Airport Extreme set to 802.11n only (5GHz), yet when I follow these instructions, I get to choose from only four options: 36, 40, 44, and 48. I'm in Europe, and according to Apple's sepcifications, I should have channels 1-13, 36-64, and 100-140 available. Any ideas as to what the problem might be? Thanks.

Sounds like you need to contact Apple--I don't have a European model to test to see what's up.

I think you are wondering why I don't just plug the ethernet between the Apple TV and the Airport Express. I can't because the ethernet is already being used by my satellite receiver. Both of these items are on the 1st floor of my house and the Airport Extreme is on the 2nd floor.
When I moved the 2 items from their original location - about 5 feet for the Airport Express and 2 feet for the Apple TV, I saw the change in speed for the Airport Express and not really a change for the Apple TV.

Ah, I see. You can plug a Ethernet switch into the AirPort Express as it can handle multiple devices. You can get a cheap 10/100 Mbps switch because the Express doesn't support gigabit Ethernet.

I am in Germany and have the same problem with my Timecapsule...the highest channel is 48. Any suggestions? Anybody? Thank you in advance! And thank you for this great article!

Thank you for a fantastic article! I just setup my new Time Capsule and I have a 4 year old Airport Express that I am using to extend the range of my wireless network. The set up is working but here is my question: I have three core 2 duo MacBook Pros. Would you recommend I upgrade to a new Airport Express to take advantage of the n network or am I wasting $100 for a little gain if I upgrade?

This is most likely due to european regulations which most likely wont allow broadcasting signal at same strength as the US regulations alow. There might be away around this, by hard-resetting the APExtreme and set it up with the profile for US. (Would how ever be violating EU commmunications laws I guess).

Tricky question! The simultaneous dual-band Time Capsule can keep the 5 GHz band super fast even with an older AirPort Express, because it's extending the network to the Express via the 2.4 GHz band. The MacBook Pros, if in range, are all using the 5 GHz network (unless you separately named the 2.4 and 5 GHz networks), and thus you're not being slowed down nor would you get a speed improvement from an 802.11n AirPort Express.

I have a two story, 3k sf house wth cable Internet service through TimeWarner cable. I tested my network connectivity using SpeedTest.net. When my laptops are near the TimeCapsule, which is upstairs, the download speed is close to 15 MB. When they are near the older model Airport Express, which is downstairs, the download speed drops to around 2 to 3 MB. If I unplug the Airport Express, the downstairs speed drops to 1 MB. This tells me the Airport Express helps to extend the range of the TimeCapsule but should I experience such a dropoff of speed? Is there something I can do to increase the downstairs speed?
