I was very happer after buy my new computer Dell Vostro v130, but after install Linux on it I’ve realized that the download speed via WiFi was very slow! To solve this I found two “solutions”, one of them works, but the other not (for me).
The solutions that didn’t work is more easy, so I will start with it,
you must install
linux-backports-modules-net-natty-generic, you can do
it via synaptic, ubuntu software center, aptitude, apt… I show you a
screenshot doing it with ubuntu software center:
The second “solution” is deactivate the hardware cryptography of the module, I don’t know if this could cause security problems or instead use hardware it will use software crypt, anyway, it is the best solutions that I find until the moment.
To do that, you must create the file
options ath9k nohwcrypt=1, you can do it easily with:
echo "options ath9k nohwcrypt=1" > /etc/modprobe.d/ath9k.conf
If you have any questions, or you find a better solution, please, let me know.
