You're showing very poor signal quality here.

Temporarily relocate your laptop right next to the access point antenna, 
wait a while, and see if your rate improves.

You have your bit rate ramped down to 1MB/s because your wireless hardware 
thinks it's getting a very poor signal from the access point. Almost no 
signal at all, only 16% signal strength.

Generally, my understanding is that this is driven entirely by your wireless 
card. iwconfig is merely reporting what the wireless card is doing, and the 
host operating system has no say in the matter.
