[gentoo-user] Recent networking problems

[Peter Weilbacher]

Hi all,

since about two weeks I have been fighting with networking problems on 
a laptop. It all started with a big sync & world update that gave me new 
udev-171-r5, wicd-1.7.1_pre20120127, tuxonice-sources-3.0.17, 
openrc-0.9.8.2, among other things (I'm mostly running stable). Symptoms 
are that I cannot even get wired _listed_ in wicd, and when connecting 
to various different wireless routers, the connection died quickly. The 
e1000e driver (for wired) apparently never detects when a cable is 
connected, and when trying it through /etc/init.d/net.eth0, dhcpcd times 
out when waiting for a carrier... I tried alternating kernels (tuxonice- 
and gentoo-sources, both older and new ones between 2.3.38-r1 and 3.2.1) 
and kernel configurations as well as downgrades of several suspect 
packages, without success.

Does that ring a bell with someone? Any advice how I can track down 
these problems?

Cheers,
    Peter.

There was a thread a while back about wicd quit working. The solution
then was to edit /etc/wicd/manager-settings.conf and change the
backend from "external" to "ioctl".

Yes, I had seen that. Of course that doesn't help with my problem, since I
cannot connect wired even when bypassing wicd.

I was hoping for some hints which packages might be involved with finding a
wired connection. The kernel certainly, maybe udev, openrc (when using 
/etc/init.d/net.eth0), but which others? And how can I reconfigure those to
let me debug what's going on?

Cheers,
   Peter.
