Yesterday I've discovered bug in module rtl8169. This module is using for example by Realtek RTL 8168C(P)/8111C(P).

Even if you set correct address/gateway internet will not start up.

The fix:

You must download another module (rtl8168) from r8168-8.008.00.tar.bz2 and copy it to your machine.

# rmmod rtl8169
# tar jxf r8168-8.008.00.tar.bz2
# cd r8168-8.008.00
# make clean modules
# make install
# depmod -a
# insmod ./src/r8168.ko

And you sholud add this line:

rmmod rtl8169
modprobe rtl8168

to /etc/rc.d/rc.local
Now set your ip,gateway,dns and restart computer.

Dont forget before my instruction you must to download kernel.lzm from and extract to /.

That's it.
