I admit to having no knowledge of this stuff ... a router makes nice edges on wood, a blade is a shiv and WIFI is the forerunner of stereo.
See?
Absolutely dumb about this stuff.
It just seems that some sort of electronic device can be invented or built that would zap into (like an induction timer light) a telephone line, or satalite dish.
I thought Wifi was what Diane Feinstein’s husband called her in private?!?
Consider your ISP (Internet Service Provider) to be the paver for the on-ramp onto the information superhighway. The internet is essentially a collection of storage stations where information is made available via web sites. You have to have a connection point to send and receive information over the internet. An ISP gives you that connection.
The cost is loosely governed by the value - which is usually calculated in terms of the speed and reliability.
The reason it isn’t free is that it’s worth something.
See - simple!
(Or was Wi-fi-fo-fum what the giant said when he discovered Jack of the beanstalk fame?) ;-P
