Ubuntu Wireless Compaq Mini

First lets see what is your wifi card info, type the following in a terminal:

lspci | grep Wireless

My info is:

02:00.0 Network controller: RaLink RT3090 Wireless 802.11n 1T/1R PCIe

Next you have to install the dkms package:

sudo aptitude install dkms

Now download the file rt3090-dkms_2.3.1.7-0ubuntu0~ppa2_all.deb from this page (I’m using Ubuntu 10.04, you can choose whatever best fits your version)

After download is complete, you can install it with:

sudo dpkg -i rt3090-dkms_2.3.1.7-0ubuntu0~ppa2_all.deb

Wait a couple of minutes, reboot and you’re done.

Happy wardriving! :p
