Well, i've been brainstorming about my own setup and I was wondering about wireless LANs.

Do typical wireless hubs have public/private key protection?
If I have a router or NAT Router, will the wireless machines be able to see my wired machine on the same router?
Will I be able to control my wired machine if behind a router or NAT router?
If I am behind a router/NAT, should I get a wireless router (if there is such a thing, i dont know )?


Just wanted to know
