i am always using the latest version of ubuntu,but my main board of my acer5520g broke down under 9.10 last month,the acer company changed my main board and i installed 8.04-i386 LST for safety.
but i find the wireless card does not work, i search the google for help,it seems i should install madwifi,but i found no valid download,after a lot of attempts i surrender.
SO i put up this question
i need a driver for my wireless card (notebook type acer5520g ,wireless card AR 5B91(detected under windows (though i am a big fan of linux and a supporter,i am using two systems and waiting for the 10.04 LST to save me from virus braced windows)
i even can not detect the wireless card under ubuntu 8.04 but it works ok in 9.04 and 9.10 after the installation.

thanks to google and the original author it took me almost 6 hours to find a compromise solution :
use the compat-wireless-ath9k_20080916-debgen1_i386
download it,install it, then go to System>Administrator>Hardware Drivers enable it and reboot,you will see the wireless card is working.
because you can't use this driver to do aircrack ,it is called a compromise solution.
Can anybody help me to find a driver for this card to do aircrack test.
