Old Trick to BOOST WIFI SIGNAL SPEED

There are many ways to boost wifi signal speed but I recommend this old trick because of it's materials: Cheap, recyclable and friendly with enviroment !

Don't waste your old things. Time to reuse something XD

(1x) Coke can (recyclable materials)

(1x) Wifi router

(1x) Scissor

(1x) Cardboard (recyclable materials)

(1x) Random glue

2.1. Cut coke can, use it's body only

2.2. Cut the cardboard, make 2 parabols

2.3. Carve a hole at the middle of parabols

2.4. Stick them by glue

2.5. Set up the device onto the wifi atenna
