Mesages output for wlan0 

Description of problem:

Slow sluggish throughput.
What does this mean...
Hit enter or click then wait....for web page to display. 
Usually paints the screen in bursts.
Fairly useless this way.

Same response when accessing local device (Router)

Never never approaches "N" Speeds
Using WPA2 AES mode.

Router = Dlink DIR-655 latest firmware.
Card = Dlink DWA-652

Note: Cards must be inserted and ejected twice to work. 

I have two card with the same chipset they both behave the same way.
Ath5k on the same system works well, using of course a different card.

Version-Release number of selected component (if applicable):
