Do I have to call my internet provider and pay to add internet service to a used verizon fios router that I bought from eBay or will a coax cable do the trick?
What service do you have now?
Cable or Verizon FiOS?
What equipment do you already have?
Just having a Verizon router does nothing special, unless you also have Verizon service to your house.
Which specific Verizon router did you buy?
What are you actually trying to do?
