Airport extreme dual band 802.11 making "buzzing" sound when power supply is attached
Hi,
what most likely is wrong with my Airport Extreme?
My Airport extreme dual band 802.11 is making "buzzing" sound when power supply is attached. The sound vanishes right away when the supply is disconnected and starts as soon as you plugged it back in. This started two weeks ago and it is really annoying.
Thx,
Laura
