I can confirm the same problem: I'm the happy owner of Asus G53sx-a1 laptop running 11.04 currently. The original ath9k driver that is installed by default craps out on me every 5 minutes or so if I download stuff at max speed. So I have installed compact-wireless driver following:
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------- wget http://wireless.kernel.org/download/compat-wireless-2.6/compat-wireless-2.6.tar.bz2 tar -xjvf compat-wireless-2.6.tar.bz2 cd into_folder_that_was_created ./scripts/driver-select ath9k make sudo make install sudo make unload sudo modprobe ath9k ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------- With this the driver wlan is stable BUT the speeds are a half of what they are used to be. Before I installed the compact wireless driver I tried the suggested: code: sudo ifconfig wlan0 down sudo rmmod -f ath9k sudo modprobe ath9k nohwcrypt=1 sudo ifconfig wlan0 up No effect. I have tried the same with the new compact-wireless driver with no improvement as well. I would appreciate any help or advice.
