Unless you want to shell out some money for a T1, you will need some sort of service provider, be it cable, DSL, or wireless. There are places that provide free WiFi, however, I assume you mean at home instead of trudging to the library every time you want to get online.
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.
A T1 line is only 1.544 Mb. Any cable internet service built in the past 10 years should put that to shame.
