Make sure you have the correct ssid and password (it's case sensitive) , plus which authentication methods you are using, WEP, WAP, WAP2. Try them all.

Seems to be a rash of these today?

Try turning off NFC. With the Jellybean 4.2.1 update, NFC is turned on by default. Go to Settings> more> and uncheck the NFC box. This has worked for many.
