I have a friend with a small business that would like to have a wi-fi setup on his network, but given that customer transactions are processed on the network, that just is not feasible for security purposes...(and corporate says NO).
They currently have DSL fed into a 4-port Cisco router, which sends off to the 3 computers in the business (one office PC and two point of sale systems) via ethernet cables.
I would like to leave that as is. In addition, I would like to be able to add a wireless router to the Cisco router, but have it be totally separated from the rest of the network so that if my friend wants to bring his laptop in to his business, he can use it to surf the internet without fear of spreading a virus to the hardwired portion of his network, or that if somebody hacks the wi-fi, the point of sale systems would not even be visible to them, and the other way around too (anybody on the ethernet cable connected computers would not be able to see the wi-fi network)
Does this make sense to anyone? I hope so as I need some help. Thanks!
