In the real world, each wireless device has a range upto which it can provide wireless connectivity. Packet Tracer simulates this range with the use of physical workspaces. We can see what happens when a laptop with a wireless interface is moved out of wireless range. For this exercise, we'll use the following topology:

This topology has a wireless access point (Access Point0) connected to a switch (Switch0), which is connected to a PC (PC0). We also have a laptop with a wireless interface.

Configure IP addresses on both the PC and laptop; we'll use IP addresses 10.0.0.1 and 10.0.0.2 respectively. Now ping these devices from one another to test connectivity. Moving to the physical workspace, navigate to Home City | Corporate Office. You'll find a round mesh that represents the range of the wireless access point. We are now going to move the laptop to the new office building, out of the wiring closet, and place it in the corporate office, as shown in...
