Network problem

Hello everyone,

I just aquired a new Lenovo G770 laptop and am having a strange issue with
the Ethernet Controller.

Network connection works fine for a few minutes then dies. The interface
is still configured though but it just stops working. There are no error
messages in dmesg either.

My router is not a problem. Access is granted and it does work to begin
with and the logs show nothing abnormal.

I've seen a few threads concering the G770 with Ubuntu but nothing that
addresses this problem.

Output of ifconfig -a

Anybody have an idea what could be happening with the Eternet controller
and how I can fix it?

Another issue are the function keys. On my old Thinkpad, the
tpb package worked very well, however, that package isn't available on
amd64. What other possibility is there to get the function keys to work?

Thanks for any help!
