power manager won't hold settings

[liblit]

In Power Manager 3.30, I want 'Maximum Performance' for the Wireless Adapter in Advanced Settings when running on AC. It really speeds up my internet. But the setting sticks for one or two days and then goes back to the Maximum Power Savings default. Anybody know a way to lock this thing the way I want it?

Have you tried going into device manager, advanced properties, power options for the WiFI adapter and selecting maximum performance?

Wouldn't that set it permanently on maximum performance?
I want it to use a power-saving mode on battery. I just want this on AC power.
