How to install ndiswrapper for the IBM 11a/b/g WLAN adaptor
Usage of the IBM 11 a/b/g adapter with ndiswrapper:
Because I had massive problems getting the madwifi driver running on kernel 2.6.13 I gave ndiswrapper a try - with impressive success:
- Thinkpad T41p 2373-GHG
- Kernel 2.6.13
- Ndiswrapper 1.2
- 802.11bg WLAN Mini PCI Express adapter software v 18.104.22.1685
Configuration of Ndiswrapper
Enable wireless status led
I once had the problem that the wireless led status doesn't come up with loading the driver. After a while I figured out that the driver could be configured through a config file that is located in /etc/ndiswrapper/net5211. When you load ndiswrapper it tells you through messages which config file it uses.
wlan0: ndiswrapper ethernet device XX:XX:XX:XX:XX:XX using driver net5211, configuration file XXX:XXX.X.conf
Changing 'gpioPinFunc1|1' to 'gpioPinFunc1|0' in the configuration file should enable the wireless status led.
Advantages of Ndiswrapper
- full power management support (madwifi has no powermanagement support)
- connection to access points establishes fast (madwifi has problems here / especially with dhcp)
Note: You can also install the driver from an existing windows system. Mount your windows partition and locate the *.INF file of the windows driver: find -name NET5211.INF
