I'm trying to connect 2 computers over my network. It worked before when the laptop was using wireless. I decided to connect the laptop to the router because I needed a way to transfer the files, and it was way too on the wireless (2MB/s). I can connect to my laptop to the desktop just fine, but when I try to connect to my laptop from my desktop, I can't get in. It asks me for user and password. When I enter it in, it says its wrong. Any idea how to fix this? My router is the modem that ATT provides: 2wire 3800HGV-B. I'm running Windows 7 on both computers.
