When I wake my MacBook Pro from sleep, the wireless indicator displays an exclamation mark and there is no internet connection. When I click it, I get a spinning beach ball and the whole menu bar freezes up. I always end up having to force restart the computer because clicking restart just lands me on a black screen. Most programs will still open but system preferences will not for some reason.

I have tried the following:
Removing all items from Login items
Ethernet connection
Relaunching Finder
Restarting SystemUIserver in Activity Monitor

What should I do? If nothing works, my last resort is to Clear HDD and reinstall OSX.
