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.

Regular Ubuntu ath9k driver: 25 kB/s
compat-wireless ath9k driver: 4.2 MB/s

I can also confirm this on a Asus X71 SL laptop, with a Atheros 928X wireless adapter. Same symptoms as above.
