How to keep ndiswrapper configuration after reboot?

As heartsmagic says, the solution was to add ndiswrapper in a new line of the file /etc/module:

gksu gedit /etc/modules

Save, close the file and reboot.

After reboot, check that the module was loaded with:

lsmod | grep ndiswrapper

(this was my own question but I lost that unregistered account).

The open source driver for my Atheros AR5005G (ath5k module) doesn't work for me. What I did was blacklist the open source driver and the install ndiswrapper. There is a nice graphical interface called "Windows Wireless Drivers", to be found in the repositories. Works all fine, but of course when you reboot it's gone.

The solution was found in the excellent documentation. You want section 3.7. On my laptop it works perfectly. (Fujitsu Siemens Amilo Pa 1510)
