when setting up an airport, you plug the cable modem into the WAN port, right. well i did that and both of my computers wont connect to the net. they only see the base station ip address and they wont reconize the internet, even though they say its connected. when i plug it into the LAN port, the one computer reconizes the internet with a long ip address while the other provides a short base station one. i have that assign ip addresses thing checked and i have tried everything i know to fix it. i am running tiger on both computers and i am stumped. my father is relying on me to fix it so he can use the net on his palm and ibook. the power mac, which is working with the net, is connected through airport.

That's a lot to check.
As stated above the Airport Setup Assistant is much easyer, but this is a good way of checking things out.

How is it working?

Hi,

Not sure if this is the problem at all but when I first bought an Airport Extreme station (same time that I bought the Mac), I ran afoul of a problem with the modem itself. I had a D-Link modem that only supported a single computer and saved its setttings based on the MAC address of the ethernet adapter that had set it up. The problem I had was that I originally set the modem up by connecting it directly to the PowerBook, saved the settings for connecting to my ISP, and then attached the modem to the Airport Extreme station. The effect of this was that the PowerBook was unable to connect to the Internet because the MAC address of the Airport Extreme's ethernet adapter did not match that of the adapter which setup the modem. This drove me nuts for ages (I thought the problem was with the Airport Extreme station).

Anyway, in the event that this situation is in anyway similar to the problem that you are having, ensure that you connect to your modem to set it up via the Airport rather than directly.

I've bought a new modem recently that doesn't appear bothered about which computer sets it up and which one connects to it so this issue doesn't apply to all modems.

Many cable modems require going through the powering-down and restarting waiting until all lights are green and steady TWICE in order to clear them to accept a new MAC address.
