Keywords: boost Wi-Fi, router signal, beverage can I. INTRODUCTION When your life is nothing but trolling and viral videos, having a bad Wi-Fi connection can be incredibly irritating. Poor loading times, lost connections and more can put a strain on your time browsing the internet. However, there are some ways to improve your Wi-Fi connection. However, even in the bleakest situation, there are heroes, and in this case its beverage cans. If you ve ever had a TV with an antenna or a radio, you ve probably heard of the trick of using tin foil to improve the signal. Using a soda or beverage can to improve your Wi-Fi signal works in a very similar way. The metal in the can and the shape of the can when cut open can focus the signal to and from your router. The only things that you ll need to achieve this are a beverage or soda can, a utility knife, a pair of scissors and some form of adhesive that can easily be removed like tape or adhesive putty. 122

2 II. SIX STEPS FOR CREATING BEVERAGE CAN DEVICE A. Clean Out the Can Practically any substance that is found in cans like soda, beer, juice and more can create a sticky residue on the inside of the can. Fig.[1] This can attract bugs and make your router sticky. Before you start cutting apart the can, thoroughly rinse it out with soap and warm water. Dry the can as thoroughly as possible. Figure1. Clean the beverage can B. Pull off the Tab The tab for the soda Fig.[2] can really has no use for this project, so it s best to remove it. To remove the tab, simply bend the tab back and forth until you hear it snap. Figure2. Remove of beverage tab C. Cut off the Bottom of the Can Grab a utility knife and carefully cut a straight, horizontal line around bottom of the can at the point where the sides of the can start sloping to create the bottom Fig.[3]. Cut very slowly to ensure a clean cut and to avoid accidentally cutting yourself. Once the bottom is completely removed, safely dispose of it to avoid accidentally grabbing it or stepping on it. Figure3. Cut the bottom of can 123

3 D. Creating the Base The base for your Wi-Fi extender will be the top of the can. To create the base, turn the can upside down and use your utility knife to make a cut horizontal cut that is similar to the one you made at the bottom of the can Fig.[4], but leaves an inch or so of metal to keep everything in one piece. Figure 4. Creating the base E. Cut the Side of the Can Position the can so that the leftover piece of metal used to keep the base attached is opposite the location you intend to make a vertical incision in the can. Use the scissors to cut a straight line from the bottom of the can to the top Fig.[5]. Then open the can up to create a shape similar to a satellite dish. If the can is still wet at the point, thoroughly dry the can before placing it on top of your router.being careful, open up the middle piece of metal by bending it until it vaguely resembles the shape of a radar dish. Figure 5. Cut the side of the can F. Attaching the Can to Your Router Place the can over the antenna for your Wi-Fi connection through the hole in the base. Using tape or another easily removable adhesive such as adhesive putty, secure the can to your router. Adjust the can to maximize the signal Fig.[6]. Basically the can should be splayed out, creating something similar to a sail around the router s antenna. The antenna serves as a mast and the pop can helps the router function. Figure 6. Attaching the Can to router 124

4 Now at the final when we are creating the device the device is look like Fig.[7] this is the front view of the device and the direction is set as per your usage. II. EXPERIMENT AND RESULT Figure 7. Front view of device So this was done, but as I wanted to measure the Wi-Fi signal strength improvement or if there was actually any improvement at all. I chose 5 strategic locations in and around the house to measure signals Tab.[1]: Location 1 aka the college campus. Location 2 aka the bedroom. Location 3 aka the friends office. Location 4 aka the neighbour s house. Location 5 aka my playroom. Table 1. Area of experiment I did some measurement with iwconfig in Ubuntu before adding the beverage can to the router with the command: iwconfig grep Signal level Here are the initial measurements Tab.[2]: Location 1: -50 dbm (Quality: 60/70) Location 2: -41 dbm (Quality: 69/70) Location 3: -58 dbm (Quality: 52/70) Location 4: -83 dbm (Quality: 25/70) Location 5: -32 dbm (Quality: 70/70) Table 2. The Initial Mesurment I did some measurements with the beverage can as shown above, but there were some improvements in some locations but results were not that great Fig.[8], probably because the signal of the middle antenna was blocked by the beverage cans, so I adjusted the middle antenna to be horizontal and made the beer cans vertical so that it looks that way: 125

5 Figure 8. After inline beverage can The beverage cans make the signal directional so the signal would be likely to gain strength where they can are pointed to and lose in the other direction. I pointed the left can (on the picture) towards my friend s office (location 3) and the right can towards my neighbour s house (location 4) since I m such a lovely bloke. Location 5 is between the router and location 3 Tab.[3]. Here are the measurements with the beverage-can improved- Wi-Fi-router: Location 1: -50 dbm (Quality: 60/70) Difference: 0 dbm. Location 2: -50dBm (Quality: 60/70) Difference: -9 dbm. Location 3: -53 dbm (Quality: 57/70) Difference: +5 dbm. Location 4: -77 dbm (Quality: 30/70) Difference: +6 dbm. Location 5: -30 dbm (Quality: 70/70) Difference: +2 dbm. Table 3. Result after device proper stick So Wi-Fi signal strength can be improved with a beverage can. But this should only be used, if you have specific areas (or directions) where the signal should be made stronger as other place will lose signal strength. IV. CONCLUSION I ended up using an aluminum beverage can the sides of the can did not fan out, so I just let them be. I also decided not to use adhesive, just in case it would do any possible damage to my wireless router. Furthermore, my router does have antennas like the one in the article. That being said, I wrote this entire post from inside of a room that had extremely poor Wi-Fi before I did what the article said. The can worked extremely well! Websites do not load as fast as they would if I were right next to the router, however, unlike before V. REFERENCE [1]. steps/ [2]. [3]
