4 out of 5 eggsCheap, Works, Software Sucks

Pros: Inexpensive PCMCIA card, works with Windows XP

Cons: Software is awful, don't bother

Other Thoughts: Save yourself some time and just use Windows Wireless built-in Software. It's a Realtek Driver that can be obtained from Microsoft's Update site.
