Linux support

This chip is supported by the rtlwifi driver, which is planned for kernel inclusion in 2.6.38. There are two other options available, a Linux driver available for download from Realtek, or ndiswrapper. (Ubuntu 10.4 support it now).

ATTENTION!
If you are not comfortable with running development code and have the option, order your ThinkPad with a different WiFi adapter. All other available WiFi options are supported by in-kernel drivers in modern Linux distributions

rtlwifi

The rtlwifi driver which supports this chip will be included in kernel 2.6.38-rc1. Until that is released you can install the driver from the wireless-next kernel tree or, if you are running the latest stable kernel, build only the drivers from the compat-wireless branch.

See http://linuxwireless.org/en/users/Download/ for instructions about installing compat-wireless.

Realtek Linux driver

The Realtek Linux driver for this chip can be downloaded from the Realtek website

More information about using the Realtek native driver in Ubuntu: [1]

Please note: use of this driver on Lenovo systems results in unpredictable fatal crashes on some systems! It's is *not* advised to choose this chipset.

Known problems:

* Connections randomly drop out after a few minutes (seems to be fixed in version 015)
  This problem has been observed with version 015 too. Realtek has been contacted about the problem.
* When using WPA Enterprise, entire system will freeze after a few minutes, requiring reboot
* Freezes also happen with Ad-Hoc mode from time to time

ndiswrapper

NOTE!
The use of ndiswrapper is not recommended

More information on using the Windows drivers with Ndiswrapper can be found here:[2].
