Just wanted to share the following, as I was having a lot of issues with connecting to Wifi on my Mac and managed to resolve it once and for all by following these steps:
* Pull down the Wi-Fi menu and turn WiFI OFF.
* From any Finder window, hit Command+Shift+G to bring up Go To Folder, and enter the following path:
* Turn WiFi back ON from the WiFi menu, join your preferred network as usual.
This process forces OS X to create all new preference files for wireless networking, which can be an effective troubleshooting strategy if the wifi problems began after upgrading versions of Mac OS X and even installing incremental system updates. Never even had even 1 issue with my Wifi after this!

* From any Finder window, hit Command+Shift+G to bring up Go To Folder, and enter the following path:
- /Library/Preferences/SystemConfiguration/
- com.apple.airport.preferences.plist
- com.apple.network.identification.plist
- NetworkInterfaces.plist
- preferences.plist
* Turn WiFi back ON from the WiFi menu, join your preferred network as usual.
