Re: Random network issues

said by Maxo:

Does anyone have any further ideas?

Hi Maxo See Profile,

When the connection is lost, are the NIC link lights lit? Have you tried connecting to a different port on the router? Could you add a new switch to act as a bridge between the router and the NIC? Have you tried a different NIC?

On the router, can you run a tcpdump?

I'm not a networking gawd unlike koitsu See Profile so perhaps he can chime in if he has the spare cycles.

Given that the issue does not appear on Windows, or an older version of Ubuntu, I did not troubleshoot the router at all. Also, limited testing with my laptop running Ubuntu 12.10 did not show any problems. Given that connectivity to the router was never lost I did not troubleshoot any hardware connectivity problems except I did unplug the network cable and plug it back in.

So, you're not going to run any of the tests I suggested? !

Sometimes it's easier to just do than to mind-trip over it ... I've learned some interesting things by abandoning my logic/understanding.

Good luck!

Cheers,

Touché.
I'm guessing that the issue is the one reported at »askubuntu.com/questions/169457/r···-link-wi which suggest running the following.

sudo -s
nano /etc/initramfs-tools/modules --- added r8168 (saved)
update-initramfs -v -u -k `uname -r`

I'll report back when I hear more.

Touche

Hi Maxo See Profile,

As you've figured out, it's the device driver for the NIC. It could have been the Linux device driver didn't like the router hardware etc. This is why I made the recommendation.

With NIC's so cheap, this is also why I suggested trying a different NIC. It takes all of two minutes to swap in a NIC.

This is why I was saying that at times, it's easier to simply try some different techniques, try something/anything, /different/.

The key is to only change one variable at a time /or/ to track what's been changed so you can revert/identify the culprit.

Cheers,
-pablo
