ath5k should be loaded with nohwcrypt parameter
After a lengthy thread, I was able to get to the bottom of my poor web browsing performance in Lucid Beta 2. Basically I kept gettng the "Waiting for <insert site here>..." status on whatever browser I used. Pages would load after a really long time, or sometimes not at all. My laptop uses the AR2413 chipset, which utilizes the ath5k wireless module. We were able to find that loading the module with the nohwcrypt parameter fixed my problem:
sudo modprobe ath5k nohwcrypt
psyke83 from the forums showed me how to automatically load the ath5k module with the said parameter on reboot.
sudo sh -c "echo 'options ath5k nohwcrypt' >/etc/modprobe.
Hopefully this information can help others with similar hardware. Whether this should be a default for Lucid, I am not sure because I don't know if it affects everyone the same. The thread is pasted below for full details of everything I tried to find the solution.
