[NTLUG:Discuss] Router Needed?

[Kenneth Loafman]

Stepping into the deep end here...

What I want to do is set up a subnet here that isolates the conference room 
and guest work areas from the rest of the office so that folks can come in 
and use their laptops without being able to see the rest of the office 
and/or servers.  I'm guessing I'll need a router to do that isolation.  Is 
there a different solution short of banning laptops, or forcing them to be 
scanned by our non-existant IT security staff?

If its a router solution, which one would be the easiest to set up?

...Thanks,
