I'll be more specific, use a Realtek Ethernet Card, they always work according to my experience. =)

haha my bad like this one?

YES!!! THATS THE ONE. VERY SIMILAR TO MINE COINCIDENTLY, LOL. =)
Not a bad price either. Very cheap. =) Thats the same one my cable company gave to me.

ok sweet, now if I install it on the mobo it should work right away, correct?

you should be able to. I'm using that right now. works flawlessly.

Yes, and let me know how it goes. This is probably the best method out there. - Cheers!

Just found another one for a little bit cheaper: http://cgi.ebay.com/Edimax-10-100-NIC-PCI-Network-Adapter-Card-EN-9130TX_W0QQitemZ330137417159QQihZ014QQcategoryZ511 95QQrdZ1QQssPageNameZWD1VQQ_trksidZp1638.m118.l124 7QQcmdZViewItem

I would stick to the RealTek since that one really worked for me. Buying some other company which is purely generic will most likely give you trouble. =)

Alright so I just got the new ethernet adapter and worked straight out of the box and I'm still having the internet lag a little bit, the firewire (1394) is disabled in the BIOS would there be anything else that would cause the internet to lag, in the BIOS?

How much of a difference is there in terms of lag? Is it minor? has there been drastic improvement. What is the adapter, realtek?
