Re: pci cards. will these cards work.
Definitly don't buy the Edimax card. If you are looking for cheap, I guess the rosewill card will do, it has a few good reviews. Personally I'd go with a more reliable brand like Linksys, D-Link, Belkin or even Netgear. You'll pay more money for them, but you know that you'll be getting a good product. I'm not too keen on most products like rosewill and some of the other stuff they sell on Newegg that aren't good brands.
When all else fails...Ham Radio!
I still have the same old HP DV9700T laptop I've had for years...still kickin'
