Comment 253 for bug 401126

My temporary solution (Toshiba Satellite Pro U500, driver 0014):

in /etc/acpi/wireless-rtl-ac-dc-power.sh replace RTL8192_BATT_POWER=6 with RTL8192_BATT_POWER=0 (line 15)

in this manner the wlan card never go in battery mode

I tested this solution for about 8-9 days (with and without AC cord) and I have no problem .... ;-)

[for csc: i have tested that if you change CONTROL_RTL_POWER to 0 the wlan card always go in battery mode only (because this is the default mode) and, obviously, don't work correctly ... when the wlan card is in battery mode the ping response is about 1 ms slow than in AC mode, I use this trick for testing the power card state]

another solution is setting power card state manually:

"iwpriv wlan0 set_power 0" -> AC mode
"iwpriv wlan0 set_power 6" -> battery mode (the broken state)
