I have a network under one wireless router, connected to many devices. I'd call it main network, and I want this to be private network.
But then I want to extend this network so anyone can access it, but no access to my main network.
So far this is what I could think of the network diagram, in style of tree (lv 0,1,2,3, lv 2 is private, lv 3 is public).
At the place I want to extend my network, currently I have one wired-connected PC. It leaves me with 3 options :
[Blue] install new wireless extender/repeater, connect wirelessy direct to main router
- how to divide network?
[Red] install wireless PCI card on wired PC, let public access via PC-as-router
- what is the drawbacks, pros/cons? power, time, etc.
[Green] install new wireless router, and wire-connect PC to router, but the router position will be under desk where the cable comes from.
- again, how to divide the network so PC still connected to main network?
If possible, I want to public network come through login interface before got access to internet. (Having different IP too from private network)
So, which should I set up? What additional things should I consider?
