Mavericks continually drops Wifi connection/bounces off
I am STILL having this issue and haven't found a solution. I never upgraded from anything — Mavericks was installed on my new Macbook Air 2014.
It takes a long time to reconnect to Wifi after waking up, which was annoying but I learned to ignore. Then the exclamation point started coming in occasionally — I turned Wifi off/on and this would temporarily relieve the problem.
Now it keeps bouncing off my network and joining my neighbor's (I have my network settings configured so mine is the default connection). This is important because uploading stuff is dangerous with this happening. At best it will be incredibly slow uploading, at worst it will freeze or cause an upload error. ANY help on this, anyone? I see Apple hasn't responded to the earlier posts on this subject.
