Wireless Network between Win98SE and WinXP

I just acquired a 2001 HP Laptop, and purchased a D-Link Wireless card along with the wireless hub to connect to the cable modem attached to my 1998 Gateway desktop (ancient, yes, but still alive).
I've been trying ALL day to establish a connection between the laptop and the network via the wireless card. The laptop recognizes the wireless card, but doesn't seem to be accessing the internet. It also appears to be recognizing the desktop as another computer on the network (I did run the setup Wizard on both but my version of 98SE was a borrowed copy, and I don't have the original ICS files), but the desktop won't recognize the laptop.

ANY suggestions on where to start? Keep in mind I don't know all that much about the technical stuff, so some of this may not even make sense.

Thanks!

 

I'd start by buying a legal copy of W98 so you have the ICS files, since that's the first step.

 

Yeah, but the computer I'd be purchasing it for is not even worth the price of a "legal" version. The one I used was "legal", it was an ex-boyfriend's, and I don't know anyone else who even still has 98.

Shouldn't the files not be necessary if I run the XP Wizard and then make a diskette to run it on the desktop anyhow? I've done this.
