Thanks for the responses.
Michael - yes, that looks like the card. $20 on ebay. I realize I could do an access point, but I'm trying to minimize space usage, wires, etc. I was thinking this card, a Belkin 54g card, and a big HD inside a nice, small Dell Optiplex 110 case would be a sweet little router. I know I could do it with W2K but I'm nervous about having MS technologies touching the internet directly. I started thinking about this idea as I currently run a Toshiba Magnia SG10 as a router - which doesn't allow the wireless adapter, and could use more disk space as a backup server. The SG20 does have a slot for a wireless adapter.
I appreciate the input and any additional advice you can offer.
