Title:
  Centrino Advanced-N 6200 Not Sustaining Wireless Connections

Status in The Linux Kernel:
  Unknown
Status in “linux” package in Ubuntu:
  New

Bug description:
  I'm having issues sustaining wireless connections with a HP Pavilion
  dv8 Notebook PC using its internal wifi card which is a Centrino
  Advanced-N 6200.

  While it is connected it performs well, but it often becomes disabled
  and I have to toggle it back on using a touch-toggle-button located
  above the number pad of the keyboard.

  When it becomes disabled, no wi-fi connections are listed under
  Ubuntu's network manager applet, but after toggling it back on, all
  the local wifi connections reappear.

  Sometimes this will happen 4 times in a 10 minute span, and other
  times it will sustain the wifi connection for hours. I have experience
  this behavior on multiple wifi routers, even on ones giving 5 bars
  (located 10 feet away).

  In summary, it seems like it is toggling off (as though I manually
  pressed the toggle button myself -- which is definitely not the case).
