I'm not sure what you mean by the computer with the "the card" in it. Don't both computers have wireless cards? You might check both computers in the network setup box, see if any protocols other than tcpip are installed. Windows 98 machines will bind to one protocol on startup and it's not consistant. If you find NetBUIE in there, remove it. You only need tcpip. To get to the network setup just right click on Network Neighborhood and select properties. Also, check that your workgroup name hasn't been changed. If both computers are connecting to the router and able to access the Internet properly, then as far as the wireless settings are concerned, it should work.
