I noticed Cablevision (Optimum Online)'s free WiFi advertisement on my DVR the other day and just last night, I noticed Optimum WiFi appearing as I was scanning for a wireless hotspot while dinning out. I decided to look into exactly what it is and how to go about accessing it since it is free to its cable/internet subscribers. Here is the breakdown for you:
1. You must be a Cablevision/Optimum Online customer with a valid account(number).
2. You must be within the coverage area (map), in the Northeastern region of NY/NJ
3. There appears to be 3 different types WiFi network, indoor hotspot Optimum has arranged at local businesses, outdoor hotspot and partner hotspots
4. You must create an account in order to access the WiFi hotspots, this can be done using your account number (minus the last digit) here and it has a feature that automatically remembers your login and password
I think this is a pretty good solution for those on the go. Given that iPhone 4 and iPod Touch 4G's Facetime requires WiFi, this could be a good solution for those living throughout the NY/NJ region. For more information, go here.
