Ethernet has a self-assigned IP address and will not be able to connect...

After upgrading to 10.6.2 and upgrading EFI FW (don't know if it's related) i noticed that my ethernet stopped working. It detects the cable signal tries to negotiate IP through DHCP, the DHCP server gives the IP but the en0 doesn't use it.

I also tried manually configure the IP and also it doesn't work.

tried also with a old version of SL that i know everything was working but it doesn't work now.

tested with other routers and nothing

tested with SL DVD and nothing

any clues?

Macbook, Mac OS X (10.6.2)

I have to apply an additional step: unchecking the "Use passive FTP mode" box an appling the changes didn't work, so I checked the box again and that worked fine. Thanks a lot for your help. I tried other solutions posted in different forums and this is the one that worked for me. Interesting to note that this problem exists since more than six years and Apple hasn't been able to solve it.
