What I'm thinking is since you connected successfully with a standalone 
workstation, your service is looking for the MAC address of that first 
workstation you connected to Verizon with and since your router has it's own 
MAC address, the router is not able to connect because it doesn't have the 
same MAC that Verizon is looking for that matches the first computer.

I would look in the configurations on the modem that Verizon provided for you, 
for the MAC address of that first computer you connected with and change it 
to match your router.

Another possibility is if your modem has this feature, you can completely 
reset it by holding in the reset button for 10 seconds or so and it should 
reset the modem back to the factory defaults, then connect with your router 
and set up your connection and finally add your computers to the router. This 
way your router is looking for the MAC of your router and not your computer.
