If I let my neighbor share my WiFi can they see my network traffic?

If I let my neighbor share my WiFi, can they see my network traffic? The short answer is `maybe'. It all depends on how you have set up your network and what kind of protection you are using. If you have not taken precautions, more people than just your neighbor could be monitoring your traffic.

The term `WiFi' is a contraction of "wireless fidelity" and is commonly used to refer to wireless networking technology. There are many ways you can set up a wireless network and all of them will have a hub and/or switch and/or router. The key differences between these devices will determine whether others can see your traffic.
