Why isn't my internet connection working
I have connected to several different wifis that I know work. It says I'm connected but won't work.
When is the last time it worked?
could be your network setting got sanfu'd.
If your wifi isn't working anywhere, I'd try:
I'd try a wired connection. Could be your wifi hardware went bad.
I'd try /System/Library/CoreServices/Applications/Network Utility.app
You could try to delete and redefine you network settings.
