Cantenna, how the fuck it works? From what I've seen it

There's a thread for stupid shit like this

By making it directional ?

Think of light source.
With reflector, you can "aim" the light further.
Turn off the light, and scattered light will be "collected" by reflector at focus point.

There is also google

i also asked /g/ one time and they said that it just works, i never get explanation for it.

its rather for blocking out other networks
routers are mostly good at dealing with a crowded spectrum, your 2$ built in laptop adapter isnt

problem with signal in your typical modern enviroment is not that device can't hear signal, it's interference
so
>while it sends signal, it aims entire signal power in single direction, so it's stronger signal for router to hear
>while it recieves signal, it blocks other signals from any other direction than router direction, so noise floor is significantly lower

can i make one and point down 2 blocks at mcdolan and have free internets?

just use a pringles can

it's probably worth a shot, but floor is usually full of metal bars and it murders the signal

you can also try to aim it somewhere below you through the window. maybe signal will come through window and bounce against something

but
