Using AE to provide internet to a nonwireless computer
I know this is possible because I've had it working before, but I can't remember how I configured it. I have an old clamshell iBook WITHOUT a wireless card and I want to use Airport Express to connect it to the internet through a Linksys WAP. So, from the clamshell to the AE there would be a short ethernet cable, and the AE talks to the WAP, which I know works because I have other wireless computers talking to it. Any ideas?
