(15.2 m).

Verify that there are no obstacles between your TV and the Modem/Router.

Check the cable that connects the Modem to the Router (if you use a separate Modem and

Modem / Router and the Internet.

If you see a valid Mac address, call your ISP and ask them to reset your network circuit to re-
register the Mac addresses of your new Modem/Router and the TV.
