Realtek Gigabit Ethernet (10/100/1000)
These Ethernet chips are supported by the r8169 driver
If you find that the driver included with your Linux distribution is not stable, you may have to download the driver directly from Realtek and compile it yourself.
In the Thinkpad Edge 11" (Intel) the driver crashes really often (at least with Kernel 2.6.36). Please use the proprietary driver r8168 from Realtek instead.
ThinkPads this component may be found in
