spinnign ball when wireless signal drops
Recently when the wireless loses a good signal from router, or when wi-fi drops there is a spinning ball in any kind of opened program. The computer stops completely and I have to force a turn-off pressing the turn-off button for several second.
Somethimes the machine doesn't start again apearing a blinking folder with a question mark.
Does anybody know what coud be?
Thank in advance.
MacBook Air, Mavericks
