When my laptop (Acer Aspire 9300) is plugged into the wall for power, I lose my wireless connection instantly. I remove the power plug and my wireless connection comes back. I've tried a couple of things, reboot, reload the drivers, all with no help. When I'm running on batteries, I can see my wireless connection along with others from all my neighbors, but if I plug in the power, they all disappear and I see nothing.... I even plugged my laptop in 2 to 3 feet from my wireless router and still nothing unless I remove power. Anyone ever seen a problem like this? Any ideas would be greatly appreciated, as its getting old only being able to surf the net for an hour at a time while running on my battery.
