Extending Wireless network with Time Capsule and Extreme

How you have described this sounds perfect.

You will get both 2.4 and 5 GHz extending

You do not need to manually configure channels or mac addresses or ...

 

I have a new Time Capsule connected to my DSL, and use an old Extreme to extend the wireless network and connect a non-wifi device to the Internet. The TC is operating on both frequencies, the Extreme on just the one it supports. Everything works without any issue, right out of the box.

 

yup, everything will work fine. Just be aware the the performance from the second wireless device will be substantially lower than what you'd get from the one connected directly to your network. Extender take a pretty big performance hit so you want to make sure you need the range before you use one. If you could run an ethernet cable from the 1st router to the 2nd router you can extend that way and not have the performance hit. That's the best way, if its possible where you are.

 

I have a similar setup, where mt APE is the main router and my TC is the bridge. I didn't want to impact my wireless network and if you extend the network wirelessly, you can only connect devices via ethernet, which didn't help since I needed coverage on the other side of the house.

I bought a set of Belkin AV Powerline plugs from my local store and they work great. Simple setup, the only frustration I had was getting the second router/bridge to be a wired bridge, not a wireless one. I do recommend these plugs, or those like it.
