May I use an older airport express with my Airport with wireless-N

Thanks for the heads-up.

I have the original time capsule/airport combo that came out. Is that not considered an "airport extreme" base station? From what I'm gathering, what I want to do with extending the airport in that unit with the old airport express I have isn't possible because the airport that is part of the time capsule is not an "extreme."

Is that accurate?

JG,

Thanks for the info.

Couple of questions. I found an apple support document on this topic that opened with this line:

"AirPort Express and all AirPort Extreme base stations can use WDS. Earlier AirPort base stations can't."

If the TC is an airport extreme base station, why can't this work to extend the network? I think I misunderstand. Here is the full article:

If I buy a new airport extreme, set it to wireless-n only as my main router, am I correct that my existing time capsule could be used as a bridge if plugged in upstairs?

Final question (and that should do it), could I take this old airport express, plug it in upstairs using the ethernet connection, and just create a separate wireless network to use with a different name?

I'd like to keep one network if possible but just kicking around short term solutions.

Thanks again.

update to this that i was able to extend it with a mixed g/n signal but not the straight N. It's up and running as desired.
