Public bug reported:

Hi, i have strange problem with my wired connection. I have RTL8168 and now im testing Oneiric ocelot ( but problem persist from 11.04 )
I have installed ubuntu via wubi.
The problem i have very slow network connection over cable - 1gbps switch - and dsl router. Speed is very varying but never exceed 100kpbs. When i turn off PC and turn off switch on PSU ( waiting to led on switch is not lit ) and turn on again . everything is ok. Under W7 i have no problem. On RTL site is driver for kernel 2.6.x only ( im not able use it on 3.x oneiric )
