Networkmanager and eth0

Segura · 2011-03-05 19:26:33

Hi all!

I'm using networkmanager on a laptop. When I start the laptop it's connected to internet using wlan0, even if I have the ethernet plugged in. If I disable wlan0, and then unplug and plug ethernet again, nothing happen. It's not hardware or router problem (It works fine in other OS and pc's).

Anyone could help me?

That's my /etc/rc.conf

What DE/wm are you using? Gnome? Do a search on the wiki for networkmanager. There is an article dedicated to it. You probably should remove the @ from syslog-ng and networkmanager too I believe.

Segura · 2011-03-06 00:06:38

I'm using gnome. I finally fixed the problem. The laptop-mode was the problem. If I do !laptop-mode the eth0 interface works perfect and my wifi works even better, I get more.

Anyway, thx.

PD: syslog-ng better without the @?

I have the same problem. Disabling laptop-mode daemon works. But is there any other solution instead of giving up laptop-mode-tools?

the sad clown · 2011-04-13 05:26:29

Did you check your settings in "/etc/laptop-mode/conf.d/ethernet.conf"?

# In practise, most of the times a user is on battery, she is using the wireless device
# Under such cases, you might want to disable your ethernet device completely, when
# on battery.
# If that is the case, set below setting to 1
DISABLE_ETHERNET_ON_BATTERY=0

If it is set to "1" it will automatically disable ethernet whenever you are on battery.

DISABLE_ETHERNET_ON_BATTERY is set to 0 on my profile.

I can provide more information.

Trial 1
I boot it up without eth0 plugged. When eth0 is plugged after startup, it connects eth0 JUST ONCE.

Trial 2
I bootup with wlan0 available and eth0 is plugged. It connects both. I unplug eth0. It does not connect eth0 again.

Trial 3
I disable laptop-mode daemon and reboot with both NIC availble. Everything works fine. It connects eth0 on every plug.

Seems like unplug eth event would cause something by laptop-mode-tools.

Instead of just turning off laptop mode tools, try disabling the line in laptop-mode.conf that autoloads the modules. This allows you to retain harddrive and cpu power saving measures and if it restores functionality then you know it was one of the modules and you can narrow down the offending module by selectively activating them.

Thanks for the hint! After some trial & error, I discovered that runtime-pm is the devil. I don't even know much about what this module does.

I don't really know either, but here is an article about it:
https://lwn.net/Articles/347573/

Also, perhaps you could try switching it back on, but with the debug setting on also so you can see why it is causing you problems.

I've turned debug on and nothing about eth0 is logged to syslog.log nor everything.log. But I found bug report which is firing this problem and has the same conclusion about it's runtime-pm problem.
