This is not a VoiceOver issue at all; my Mac is doing something annoying and I want to see if anyone else is having the same problem.
I have a 2011 MacBook Air running 10.9.2. When I wake my Mac from sleep, the Wifi status is "No signal." This happens no matter if I've physically moved the Mac around from network to network; it occurs both when I venture out and when the Mac is sitting at home. Turning Wifi on and off again does not resolve the problem; the only workaround I've found is to restart the mac. Granted, a Mac restart is a far cry from a windows restart on an actual hard drive, but I just wanted to see if any other 2011 MBA owners had seen this to determine whether it is a software, firmware, or hardware issue. It seems to happen every other time or so that I wake my mac.
