Network Configuration


I have a RTL8139 network card.
Lion recognizes it perfectly, but when I try to configure it with an authomatic DCHP, it gives me a wrong IP address and wrong Submask...

If I try to configure it manually, I can't get connection.
When I run the Diagnosis, I got the first 3 lights on green, but red in the two last...
I try everything: put DNS and Gateway and so on...

This is what I'm talking about:

Does anybody got a clue???
Thanx in advance!!!

Talking Cannot Guarantee but...

I know you siad you set it manually. Have you tried to set your Ethernet Manually with set link speed 10 and/or 100 with and without half/full duplex. I have a different card and had to use 100 Full Duplex, with static ip, subnet and gateway.
There is a small possibility that your ethernet cable will not support 1GB or 100MB even. This can be from interference, kinks/shorts, crappy quality, even length. If you had Snow Leo or another OS with same hardware then I would say....

There may also be an issue with the "network driver" (aka kext), this may help: . If you want to go a harder way (more reliable) use a EFI string and put BuiltInEthernet=No in your chameleon boot.plist.
I hope this helps you!
