Something is seriously screwed up. The bitrate on wlan0 is constantly repeating to something very low, usually in the single digits, regardless of what I set using iwconfig:
Code:
sudo iwconfig wlan0 rate 54M
Rutilt tells me it's 54M for about a second, and then goes back to something random between 1M and 10M. Always shifting. But my download speed is ALWAYS limited to 128kB/s.

This has been a problem since 8.10, when I started using Ubuntu. I am using an RT2500.
