Network connection being dropped even after updating the driver to the latest realtek one r8168-8.037.00. I am running Ubuntu 13.04.

I need to usually reboot my router to fix and or the cable modem also. Other systems connected don't have this problem.

LINUX driver for kernel 3.x and 2.6.x and 2.4.x

Also I added the following as well.


echo on | sudo tee /sys/class/net/eth0/device/power/control

Does disabling IPv6 help? – user85164 Oct 22 '13 at 19:57

This may be an unexpected solution, but are there any other 2.4GHz devices, such as cordless landline phones, baby monitors or wireless headsets in the vicinity? Your particular computer could have a weak signal, and when combined with the interference, that could cause the problem.

Oftentimes those are using the same ISM band frequencies, but since they are not WiFi devices they can jam the WiFi band and break your connection. Folks who do wireless consumer support often call those frequencies the 'junk' band because some consumer devices do pretty horrible things to WiFi signals.
