Had the same problem: Ubuntu Jaunty (9.04), Lenovo T400 laptop with Intel 53050AGN. I had slow download speeds when using wireless b (802.11b; ~70 KB/sec) and normal rates for wireless g (802.11g; ~1000 KB/sec).
Solution that worked for me: install the latest wireless drivers package (compat-wireless, http://linuxwireless.org/en/users/Download#Download_latest_Linux_wireless_drivers): sudo apt-get install linux-backports-modules-intrepid-server After reboot download speeds became normal.
