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?

I just aquired a new Lenovo G770 laptop and am having a strange issue

Network connection works fine for a few minutes then dies. The
is still configured though but it just stops working. There are no
messages in dmesg either.
My router is not a problem. Access is granted and it does work to
with and the logs show nothing abnormal.
I've seen a few threads concering the G770 with Ubuntu but nothing
addresses this problem.

Anybody have an idea what could be happening with the Eternet
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
amd64. What other possibility is there to get the function keys to
