Good news over at Zawodny’s: The “
AirPort Express can extend the range only of an AirPort Extreme or AirPort Express wireless network” part of Apple’s documentation have bothered everyone — Amazon.com’s user reviews to the rescue:
For apple users I imagine installation is a breeze… Well, I use XP and I have got this puppy hooked up to a Linksys wrt54g 1.1 router. Installation in this setting wasn’t such a nice experience. Since the Apple Express Assistant will only automatically detect Apple wireless networks, you have to install the device initially (using an Ethernet cable from your router) as its own network. Once you have done that you can step back in using the Apple Admin Utility to join your current network (you will need to type the name of the network in manually).
I don’t have the need, but I do own a couple of Linksys routers so this is good news. On a side note, I just used my AX as a portable AP for the first time. Rocks!
