Ubuntu

unstable network connection since upgrade to precise

Asked by darodi on 2012-05-08

Hi

I upgraded from 11.10 to 12.04 last week. I now have 2 problems with my network connection.
Had none of them before.

1-Sometimes, my network card disconnects and seems frozen
2- wake on lan doesn't work anymore.

Problem 1:
  - carrier is lost
  - i cannot restart the interface from the graphic network manager
  -/etc/init.d/networking restart does nothing
   -ifconfig hangs
   -I tried to restart the kernel module, rmmod hangs too.
   -the only solution is a brutal reboot with the power button. "shutdown -h now" hangs too

Here is my config:

$ sudo lshw -C network

I've got exactly the same problem.
Any solution yet?

darodi (rodi---) said : #2

Do you think we should try the latest upstream kernel? Or it won't change a thing?

I miss wol, but I can live without it.
However a machine I have to force reboot once or twice a day is not really convenient.

Launchpad Janitor (janitor) said : #3

This question was expired because it remained in the 'Open' state without activity for the last 15 days.

Tmp T (tmp-t1) said : #4

There's no answer, and the problem is still relevant to me.
Please come back to this question anyone.

darodi (rodi---) said : #5

I still have the same problem too.

Please tell me what can I do to get this problem fixed!

David Dunlap (david-dunlap) said : #8

I'm having similar network issues with this adapter using Ubuntu server 12.04 as well.

darodi (rodi---) said : #9

@David Dunlap

I don't have this problem anymore.
I think I just upgraded my kernel using
apt-get update && apt-get upgrade

FYI:

David Dunlap (david-dunlap) said : #11

My issue is mainly with overall performance of the network adapter. For example, when downloading from Astraweb Usenet, a laptop on my network will sustain 2MB/s down (20Mbit) where my Ubuntu server will only sustain ~800KB/s down (8Mbit). This is a huge difference.

David Dunlap (david-dunlap) said : #12

Further info... I just installed a simple dlink 10/100 network card I had laying around and after configuring, my download speeds and streaming is acting like it should. It's definitely an issue with the driver for the onboard gigabit nic, I feel.
