How do I use the Playstation Network with Mediacom?
If you are connecting your Playstation 3 directly to your cable modem, there is no special
setup required to connect to the Playstation Network with our service. If you are using a
router, you may need to consult your router's manufacturer on how to add the following
port forwarding options.
