Guess I accidentally posted this in the wrong forum before...
My brother just bought himself a Notebook, an Asus A6VA. It has a Intel 915 Centrino chipset, Pentium M 740 and a Marvell Yukon Gigabit Ethernet Controller. The problem is with the LAN. He is unable to hook up to his (or any other) PC to transfer data from his PC to the notebook.
So far he has been unable to ping the notebooks IP, automatic IP setup doesn't work. However Loopback Ping does work.
He has the newest drivers installed and has tried hooking up to 3 different PC's, so the problem is definitely the notebook.
When using a crossover you dont need to have a default gateway or dns servers if you arn't sharing internet too. Just give one computer 192.168.0.1 w/ subnet 255.255.255.0 and the other computer 192.168.0.2 w/ subnet 255.255.255.0.
If you are giving both computers the same ip address that is your problem.
Also, gigabit network cards are auto sensing. If both computers have gigabit you dont need a crossover cable.
