This is referring to those black boxes which have recently been installed on many of the boardwalk lamp posts (read: THE CASE OF THE MYSTERIOUS BLACK BOXES [UPDATE: IT’S OPTIMUM ONLINE WI-FI]).
Yep, they are for Optimum Online Wi-Fi.
While on the boardwalk this past weekend, I checked the available Wi-Fi networks on my phone on two separate occasions. Both times my phone automatically connected to my Optimum Online account. This begs to ask: Has the boardwalk wi-fi switch been turned on without any fanfare? Or is the big announcement coming soon? Because according to my phone, it’s already working.
