I have 2 wireless routers (ground floor - c1, first floor - c2). I would like the Ubuntu machines in my LAN to see only the above wireless routers (c1, c2) and not routers outside my building (say the adjacent building). What should I do in order to achieve this?
ground-floor-c1
andfirst-floor-c2
even when at home and at hotels and anywhere else in the world, right??? (Sounds like a bad idea to me, but just want to point out the obvious, because that is possible)
