### END INFO ###

i can do:
$ sudo iwconfig wlan0 rate 11M
$ sudo /etc/init.d/NetworkManager restart

that works for me. See:
$ iwconfig wlan0
wlan0 IEEE 802.11bg ESSID:"kackepappe"
          Mode:Managed Frequency:2.462 GHz Access Point: 00:0C:F6:35:BC:E3

When i restart, i always have to set the rate to 11M.
