For the first time since May or June 2016 using a soda can put the wireless router and it works.

But, it was a problem. A signal strength is poor (1 or 2 bar). I'm must to get a better signal from living room to a bedroom.

Eight months later, I've saw on YouTube video to improve a signal. Thanks to in this video in link below.

This is a second time to improve a signal

Now this instruction:

a pair of scissor

a knife (or Stanley knife to prevent injury)

a ruler

a permanent marker

a piece of aluminium foil (to random adjustment)

three cans of soda (why "three"? Because I'll use this to get improving signal)

(Sorry I'm a certainly half-English 'cause I'm a Malay)

Step 1: Make a Cantenna

First, make sure remove a soda can opener 'cause to more stable.

Second, trace with permanent marker and use a knife (or Stanley knife) to cut a half of base and a bottom (Tips: a top of can must cut 3/4 (or three quarters) to open a base)

Third, roll of a base upside down to widely a soda can.

Fourth, cut an aluminium foil for any length you want and cover with two soda can (Sorry this is an old aluminium was corrosion I'll don't have a new one. So, it will be OK). And the third one without using an aluminium.
