I recently re-signed up for Fios service after a brief period without service. I purchased my previous router from Verizon, rather than rent it when I had service until April '20. I purchased the new modem/router when I signed up again in July. I would like to be able to add the router I previously purchased (Fios-G1100) or the access point (Actiontec WCB6200Q) to the network that was recently setup - in order to boost the signal strength on middle floor - I have 3 floors - the main router in the basement and the access point in the 3rd floor office. Is this something that I can do? I have an ethernet port and fios cable box in this floor, so I have coax already run here.
