Hey guys , I have been asking for info on Compaq Presario CQ40 drivers on Ubuntu for quite some times in Ubuntu forum but no one replied. The wifi driver provided not that good since it only allows me to connect to wifi but aircrack-ng all not support the system shown can't allocated wifi driver. Any method to get appropriate drivers for my lappy ? and I only got gpu and wifi drivers the remanining sounds/proc drivers all don have.
