I have finally managed to find a solution to make my wifi stable in ubuntu 10.10. I have had problems with my ASUS ul30vt and the Atheros AR9285 but by installing the latest compat-wireless from yesterday my internet is finally stable.
I seriously thought of installing win7 again. But one minor problem i have is that the wifi is not turned on automatically from startup so everytime i startup i have to go to terminal and
sudo modprobe ath9k and then the wireless turns on. I have tried to make that command in startup applications but that does not work. Can i make a script or something that will turn it on from startup, or is there an other simple solution?
