Thank you for the prompt reply, Larsa, much appreciated! I doubt if I will expand my network, three more years to retirement

Please bear with me, I am not a network specialist. I have one ONT fibre connection. I want to create two separate networks. One will run a w-fit mesh (base with two satellites), and the other will have a different mesh/ make with a base and two satellites. I want to connect my 8-camera CCTV wireles...
