Public bug reported:
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).
