Comment 21 for bug 773154

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. Thank you:
