Avoid Ad-hoc wireless networks

Disable automatic connection to any new networks and limit your connections to access point (infrastructure) networks only:

• Click the "Start" button and navigate to the "Control Panel" and then to "Network Connections."
• Right mouse-click on the "Wireless Network Connection" and choose "Properties".
• Pick the "Wireless Networks" tab, then the "Advanced" button:
  • Make sure that the check box next to "automatically connect to non-preferred networks" is not checked.
  • Click on Access point (infrastructure) networks only to avoid ad hoc networks.

This configuration prevents you from automatically connecting to any new networks and refuses all ad-hoc networks, which have the potential to monitor traffic that passes through them.
