how does the internet get into my house when all the windows and doors are closed?

If you are using the internet from home right now, then your

ISP (Internet Service Provider) brought it in. This can be done

with your telephone land line, your tv cable, FIOS, or possibly a dish.

Internet will not come through the air unless

you are using your neighbor's WIFI router.

Holes in the wall are unlikely to improve your signal.

I think you have discovered the secret security implications of the internet.

It is all a part of a plot to give the CIA access to the interior of every home on the planet.

You think that the mouse on your computer is just a "mouse". This is not true.

When the mouse is left unsupervised at night it generates a mousehole just as all other mice do.

This hole not only lets the internet past any firewall you may have, it also passes it through any other type of wall too.

However you should note that it takes a lot more effort to punch a hole through a metal wall than it does through a wooden one.

Hence your wifi doesn't work so well in a steel building.

But never fear. If you attach a mouse to your ipad or portable computer then this will increase the size of the hole over time and increase your connectivity.

If its a troll question then thumbs up! if not then do humanity a favor kindly dont breed.
