I'm using a thinkpad t410s, I've noticed an improvement by turning power management off:

/sbin/iwconfig wlan0 power off

If this works for you, put it in a file in /etc/pm/power.d to make it permanent.

Disabling wireless n also works, but I have had a stable connection using wireless n with power management off (Intel 6300 card).
