ThinkPad 11b/g/n Wireless LAN Mini-PCI Express Adapter II
The ThinkPad 11b/g/n Wireless LAN Mini-PCI Express Adapter II appears to be a Realtek 8191 wireless card. Currently there are no linux drivers for this card (at least none that I can find). 
There seems to be some progress on the linux driver for this: 
Following the links above and doing some searching, it seems that it should be possible to get this card to work. There a two ways one is using the alpha/beta/? version of the Linux drivers, the second is using Windows drivers and ndiswrapper. Using the preliminary Linux drivers is described here. (Instructions tested on a Thinkpad X200s with a Realtek 8192 and Ubuntu 9.10).
- In order to use the Linux driver we have to compile them for the kernel you are using. Generally for compiling drivers you have to install some packages for this first. In the example here you have to plug in a wired network and type in the following command, this will install all necessary stuff:
sudo apt-get install build-essential linux-source-2.6.31
- Now you have to obtain a copy of the Linux drivers: , there is also a 64 bit version available .
- Unpack the driver and open up an console and go to the directory you unpacked the driver to.
- Compile the drivers using the following commands:
sudo make sudo su make install
- Lastly you have to load the freshly compiled driver by running the following command:
If everything worked fine the card should start working immediately. More information on the installation procedure including a description of the second method using the Windows drivers and Ndiswrapper can be found here:.
