I've been using ndiswrapper on my old wireless card without any problem, until I upgraded to Ubuntu 11.10. ndiswrapper is not included by default anymore so I installed it from the Software Center, then I installed the driver using the .inf driver file. The wifi started to work just fine in all the system user accounts (logging in & out was OK) but after reboot, the wireless card just doesn't work (it doesn't list any wireless connection) and I have to open ndiswrapper (GUI) and reinstall the .inf driver to make it work again.

Any ideas on how to solve this? Is it a "daemon" process or something that needs to be started after reboot that maybe is not being installed/configured by software center?

Is ndiswrapper module being loaded when system boots? You can see it via: lsmod | grep ndiswrapper If not, just add it to /etc/modules –  heartsmagic Nov 7 '11 at 1:27

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)
