I just bought a used G1100 modem/router off ebay to use with my FIOS service. I connected it to my coax cable. The Internet works fine, but it does not look like on-demand is working. I assumed because I am connected through the same coax cable everyone would work as it did before, but that does not appear to be the case. Any insight?
Is the Guide also not working? How about the LAN Coax light in the back of G1100, on or off?
It is possible your G1100 has Frontier FiOS firmware. That also may be your issue. Login to your router at myfiosgateway.com to see if the GUI has a Verizon or Frontier logo.
