hi I want to setup wifi on another laptop now what im tryng to discuss is the fact when it has been setup you can go to the wifi connection and right click on your wifi and go to properties and still see your wifi key now im trying to setup someones laptop in the house once again and so they cant get the wifi key from their laptop ?
What you need is a router that has a Guest WiFi facility, such as the Netgear DGNB2200, amongst others. Google is your Friend... (ETA) If it's just a one-off thing, you could simply reset the WiFi key to something else after s/he's gone.
