In their words
So, guys I have made wifi gun a but it seems not working as there are a lot of trees between my friend's wifi and my home ( 1km distance ), So is there a method to convert wifi to wire and transmit over here, So I was thinking about connecting a wire to my wifi antenna and dragging that to his house.
