This might appear as a fairytale to you, but with the help of a beer can you can strengthen your Wi-Fi reception. First empty one beer can and cut the bottom and the top. Then put the can, which is now similar to a tape, behind the antenna of your router and watch how the internet access speeds up. Even if the router is without an antenna, the router position may influence the speed of the internet. Moreover, avoid putting your router close to the wall or under the TV. Also, it is good to sometimes turn off then turn back again the router.
