I have a weird problem that started last night. I'm using the wireless
connection on my laptop (Acer Aspire 9300). Everything was working
great until last night.

Now when my laptop 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 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.
