Bug Description
I'm having issues sustaining wireless connections with a HP Pavilion dv8t-1200 CTO Entertainment Notebook PC (Product# WF681AV):
http://
wifi card: 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).
