Beezy :
I am quite fond of TP-links PCI and PCIe wireless cards. Dont get a single antenna card though, go for at least the double ones. Tenda are OK but i would go with a Rosewill adapter before Tenda. Obviously Linksys and the other big names will do just fine too. Make sure you know the speeds you get out of your router and if its a/b/g/n etc. You want a good match here.
Thanks, Beezy. I have a real basic Linksys WRT120N Modem. What is the easiest way to find the speed and other specs it delivers? I'm pretty sure my machine has the old PCI slots.
I just saw that there are USB wireless adapters out there. Would one of those work? I don't see that they have any antennae. What's with that?
