I am still experiencing this bug in karmic. Today I tried maverick (running from a USB stick), unfortunately the problem is still present. First the connection is fine (1.0 MB/s in my case), later the speed drops to 64 kB/s - 100 kB/s. (I'm testing the speed with 'scp'.) Then I tried: # iwconfig wlan0 power off # iwconfig wlan0 rate 54M fixed
Then iwconfig will claim the speed is 54M, but actually it's much slower. As I wrote earlier, my workaround is right-click the NetworkManager applet on the Ubuntu desktop, deselect "Enable Wireless", wait 2 seconds, then enable it again. Then the speed is good again for 1 minute to 1 day.
