I can confirm this bug - Ubuntu 11.10 64bit. I'm using wifi card Intel centrino advanced-n 6230 and the connection is VERY slow. When I try any other wifi card with another chipset, it works fine (Atheros, Broadcom..).
This hack works for me:

Create a file /etc/modprobe.d/intel_11n_disable.conf containing :

options iwlagn 11n_disable=1
sudo update-initramfs -u

reboot or sudo modprobe -r iwlagn && sudo modprobe iwlagn

Can we expect any patch for 11.10? Thanks a lot.
