I have a wireless-n wireless adapter on my computer, which uses the ath9k driver. Network Manager says that I'm connected with a speed of 130 MB/s. However, my network connection is incredibly slow. I did a test, transferring a large file over my wireless LAN, and the average speed was 25 kB/s. Let me repeat that. File transfer. Wireless LAN. 25 KILOBYTES per second. However, if I compile and install the ath9k driver from compat- wireless-2.6, found at wireless.kernel.org, my speeds increase drastically. With the compat-wireless ath9k driver, my wireless LAN file transfer test gets an average speed of 4.2 MB/s. Regular Ubuntu ath9k driver: 25 kB/s compat-wireless ath9k driver: 4.2 MB/s Something is very wrong with the ath9k driver that comes with Ubuntu.
