Eh. Couldn't find the modify button so I'll just make another post...
I'm pretty sure that the wireless broadcast from the router works, since my other desktop (with a Linksys wireless reciever plugged into it) can detect the broadcast and use it, from over 20 feet away.
However, the laptop can't detect the broadcast from less than a foot away from the router.. So I'm thinking something's wrong with the laptop =/ Grr.
Oh. And the exact thing is called "Realtek RTL8185 54M Wireless Lan Network Adapter", if it helps at all.
