Re: Network problem

The kernel may not be aware that something is wrong. Your email has garbled which driver is in use, could you please clarify and also which kernel version are you using?

Some steps i suggest are...

- see if traffic is leaving your machine (mirror ports, hubs or a cross over to another machine. then use tcpdump or wireshark)
- try unloading and loading the driver, does it work again?
- check what options are available for the driver, and play with any you might have
- update your kernel

some more exotic things to check...
- check that iptables isnt being triggered by something?
- it could be an irq conflict, especially if the card (or driver) doesnt play nicely with shared irqs. you may be able to clear the share by disabling an unused serial or parallel port - following from the above, you could change to polled rather than irq and see what happens. polling uses lots more cpu (ok thats an over simplification, it is better in some circumstances)
- maybe your dns lease is expiring?

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.

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!
