I have a big problem with my wirless connection

[Iamafish]

So I got this stupid wirless thing since my computer is in a room where its very difficult to run wires to.

I have a linksys router and a D-link pci card.

I got D-link becuase the reviews were mixed for linksys and D-link, and D-link was cheaper.

The D-link instructions suck so I just used windows to connect. Recently the pci card just stopped working. The packets sent were high, and recieved almost 0. Ive had this problem on my regular computer, and the ip address was somehow changed (probably a virus).

So, while trying to fix this, I figured out how to connect to the router using the D-link software, but the packets recieved are still low (there is connection between router and PCI card, but no internet connection). I ipconfig my comp, and it is different from the IP of my router, or my other computer, which ever its supposed to be. I dont know if that may be the problem, and I cant remember how to fix it.

The defualt gateway is not displayed. Instead of just IP address, it says Autoconfiguration IP address, and there is nothing under connection-specific DNS suffix.

Subnet mask is the same on both computers.

I've tried to give all the information which I think may be usefull, if you can help me in any way that would be great. If there is anymore information needed to solve this, I will reply as soon as possible.

This shits really setting me back, thanks.
