For new version of software, it is better to wait

after all(many) problems solved, download stable one

normally, ubuntu wants to publish new version as soon as possible and

either they trust developer or they have not enough time to test...

Thanks to all who bothered to answer...

I found this (http://bernaerts.dyndns.org/linux/49-debian-server-rtl8111) and proceeded as told. Problem gone...

I still wonder, why the broken driver is in the last version of the Ubuntu server...?

Find driver for linux

you find driver in x.tar.gz or maybe x.run

if x.run find you can type this

./x.run

or x.tar.gz

after type this "tar xf x.tar.gz"

read INSTALL,README file

Download source code of realtek "r8169" , then

1)tar xvf ...

2)./configure

3)make

4)make install

read "README" file before starting

Try blacklisting each driver and compile the one not built in manually.

It's possible to get a perfectly stable 10.04 system but haven't tried on Natty.
