Initial setup-xfinity modem blinking orange

Hello! I am new to xfinity and was trying to get this wifi setup in our home we just moved into. I followed the instructions provided with the modem and cables sent to me, but every time my router blinks orange indefinitely. I have tried every coax outlet in the home (4 total), I have tried resetting the unit/unplugging, and even a different coax cable.  The coax outlets are in open areas on the top floor of the home, so I don't think it is a connection issue there. From what I have found on this page and research, it sounds like the xfinity line may be off at the road? Can I get this turned on remotely or is this something I can connect myself? Not really wanting to wait 3 or 4 days for a service person to come out, and they are only available when I am at work. Thank you!
