openSUSE 12.1, Wired LAN doesn't work

Alright, I’ve installed openSUSE 12.1 (Linux 3.1.0-1.2-desktop i686) on my new Laptop this week. Everything but the wired LAN works perfectly on it. To be exact, when I activate (or reactivate) the network, it connects to the internet for some seconds but then fails without further notice. Wireless works flawlessly.

I haven’t tried any other distros on this computer yet, so, I have no reference if there were any other drivers working, or how older Kernels behave on it. Any suggestions?

(Thanks in advance)

There is a report of a problem with driver tg3 in kernel 3.1. When the wired
connection fails, check the end of the output of dmesg to see if anything was
logged.
