Importance of WiFi and other tech while traveling?

A big concern would be that unlike power, water and sewer, wifi is ever evolving and requires pretty much constant updating and upgrading. You would be in and out and then gone like a thief in the night. Even if you took the path a previous poster mentioned, help set up a system that blocks Netflicks, Hulu and the other streaming services, what happens next year when the services of the moment are completely different? I need someone whom I can call and get help from ASAP.
