Can't get your MoCA bridge instructions to work

I followed your instructions for replacing my Actiontec router with a MoCA WAN bridge (the Netgear MCA1001), but it just wouldn't work. I plugged everything in, but the coax light on the Netgear wouldn't light. And yes, the coax was plugged into the "coax in" port :) What might be the problem? http://www.dslreports.com/faq/verizonfios/3.2_MOCA#16793
