What you’ll need:

• 1 Foot Sheet of Aluminum Foil (Be Sure to Cover the Aentena to the Top) Note: Some routers won’t have an external antenna.

Create a “C” shape with the sheet then place the aluminum foil behind your router. The shiny side should be facing inside the curve, toward the router. Fold out the bottom of the sheet to create a stand if it needs extra support to stand upright.

Last, check the connection by going where you’d like to see an increase of signal such as on the couch or in the kitchen. Type “Google speed test” into your phone or computer browser’s search bar. Then run the blue “run speed test“ to get a report containing the connection speeds.

Aluminum Foild Behind your Router for Security

Apparently, placing aluminum foil behind your router is good for more than only improving speed and efficiency. The Dartmouth team also discovered the hack may be a successful way to ensure a secure connection. Placing aluminum foil behind your router limits how far the WiFi signal can reach, meaning hackers won’t be able to reach your connection, especially if you arrange the signals to avoid areas where a connection is never needed. “Such physical confinement of wireless signals serves as a complementary method to existing network security measures, such as encryption, and hence raises the barrier for attackers,” the researchers wrote.
