I currently have an existing Fios phone, TV and internet service. I need more reliable wireless service at the back of the house. I can't poke any more holes in any of the walls (I rent). There is, however, an existing coax run to right where I need to put the router. I have made a great score at a yard sale. New in box 1100 router for 5 bucks! I want to put it on the coax that exists to the back of the house.
THE QUESTION: How do I configure the second router to give me a second wireless network(actually two, 2.4Ghz and 5 Ghz) while not screwing up the existing fios "system" and still be able to communicate between the two routers? At some point there will be a NAS, some cameras, and computerized test equipment that will need to share the network. Customer support says it won't work, but I'm pretty sure it is possible. Can anyone point me in the right direction? I really DO NOT want to screw around with any wirless extenders, especially since there is existing coaxial cable right where it needs to be. Thank you in advance for any and all help
