Thing is, the parents comment makes no sense because it's implying that your wifi drivers would stop working if you connected to different wifi.

OS X has plenty of problems, see: http://www.imore.com/os-x-mavericks-problems-drive-me-nuts-h...

I've personally experienced many of these my self. OS X is cool, but I wish the fan base would stop acting like it never has any bugs or issues. OS X does get bugs, OS X does crash, OS X can break, OS X does not always 'just work'. Just go to discussion.apple.com and look at all the issues everyone is having. OS X is a great OS though, but it's not infallible.
