Brand new to fulltiming, Internet help please!

While more expensive, I've had marvelous luck with a Verizon JetPack (also called MiFi). It gives me an internet hotspot and 5 computers can join it with regular wifi. My daughter was doing her college courses on-line while we were driving 65mph on an Interstate through Western Nebraska. Never dropped a bit. Verizon has great coverage. More expensive, yes, but I've been satisfied with the results.
