Connection Trouble

Greetings!
I got alittle problem. When I log on Aion, my internet is very slow. Thats because my Network Card. Anyone who knows about this and can help me?
I got 2 Network Cards. 1 that can recieve 400mbps. And one that can recieve only 100mbps. I realy want to make the 400 one work. But the problem is, when I turn it on, it doesn't want to recieve any IP Adress, Gateway, or anything. When I press repair, it says: Problem can't be solved: TCP/IP Aint activated for this connection. While, its clearly activated, aslong I know. And I checked it. Maybe I check wrong. But I don't think so. Anyone knows what I have to do? =)

(To be sure.
The 100mbps = Realtek RTL8139 Family PCI Fast Ether - Network Card.
The 400mbps = Texas Instruments OHCI Compliant IEEE 1394 Host Controll - Network Card.)

 

its just show like that, becoz i guess u got router thats all. anyway you can try this guide http://forum.gameznetwork.com/showthread.php/73858-Speed-up-ur-pc-and-connection(GUIDE)! . and about ur speed , do speed test on www.speedtest.net, and post results here.

 

Thanks. Will try. =) I hope it works. Because, with the 400mbps I don't got internet. Cable plugged in or not. =S So if I can get programs to make it faster.. then It will be realy good.
