Public bug reported:
Support for the realtek r8101 Ethernet interfac is handled by r8169 driver on
Ubuntu Precise. However, the link is very unreliable and fails to connect most
of the time. Speed negotiates down to 10Mbit/sec usually, half duplex, even
when using the workaround 'sudo ethtool -s eth0 autoneg off'
There seems a problem with the link speed negotiation?
Won't connect at higher speeds at all.
It's not possible to use the r8101 driver previously available as this is
supplied by Realtek only for 2.4/2.6 kernels. It won't compile under 3.2.x
