Not only is this a smart way to use a beer can for an ultra-cheap tech hack, it also means less messing around with cardboard and aluminum foil, as required by many other methods. This method has a proven effect, boosting WiFi reception from around 2 bars to an average of 4, ranging between 3 and 5. Give it a try – all you need is an empty beer or soda can!
Step 1. Gather the required materials and tools
These are listed under "Requirements".
Step 2. Clean the beer can
Make sure no residue is left behind.
Step 3. Remove the can opener
Step 4. Cut the end where there is no opening from the can
Use a Stanley knife or something similar for this.
Step 5. Cut the end with the opening for the largest part all around
Leave a small piece attached to the can so that the can can serve as a stand (see the white line in the illustration).
Step 6. Cut along the center of the can in a straight line, opposite the piece of metal that is still attached to the rest of the can
Step 7. Carefully open the middle piece of metal by bending it so that it looks something like a radar dish
Step 8. Place the completed WiFi extender on your router
Position it so that the antenna extends through the opening.
Step 9. Secure the base of the can to the router with a piece of tape or other suitable adhesive
Now it's time to test how much your Wi-Fi is boosted!
