    4 out of 5 eggs Cheap, Works, Software Sucks

    Pros: Inexpensive PCMCIA card, works with Windows XP

    Cons: Software is awful, don't bother

    Bottom Line: 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.

    5 out of 5 eggs Painless

    Pros: Just works as advertised. Dropped this in a P3 laptop and loaded drivers and was able to connect right away.
