The signal strength meter on my Windows 7 laptop keeps changing from two to four bars of strength and back again. It's starting to look like a peak meter from a 1980's stereo. The machine isn't being moved and it's plugged in for power.
If we assume that the meter is accurate (that the machine is seeing a 50% loss in power then getting it back repeatedly) then why is it happening?
Is there some sort of power saving feature turning down the signal on the laptop or should I start shopping for a new router?
