I have an Actiontec modem. I don't use its wifi but instead use an Apple Airport connected to one of the ethernet ports on the modem. For security reasons, I would not want some wifi devices to use the Airport network. I tried setting up a guest Airport network but was unsuccessful and/or it involved reconfiguring the FIOS modem beyond what I would be confident doing. I had also been told that turning on the FIOS wifi would be problematic.
So I was wondering about attaching a separate wifi router to another one of the FIOS ethernet ports, with its own password. Would that even work and if so, would it create an independent wifi network such that if it were hacked it would not provide access to my existing Airport network?
Thanks, and I am not very knowledgeable about networking so please keep the jargon to a minimum.
