Free wireless at CO's President's Clubs in EWR.
With a 7 hour layover do yourself a favor and pay for a one-day pass to the CO club and enjoy the free drinks, snacks and workstations along with the free wifi. Sure beats sitting on the floor outside of the club trying to steal the signal.
A day pass is $45
