RV Wi Fi System

I apologize...... I inadvertently left out two pieces of important information...... since this upcoming trip will be the longest we have ever been away from our permanent home, I am going to be doing a lot of my personal business (some of it quite extensive) from the motorhome where ever we are. I have a Dell laptop which works great but my business requires a good bit of typing and I can't type as fast or as accurately on the laptop (short stubby fingers). I also have a Samsung 4G phone but don't want to include it in my business setup. I also have a Dell printer in the coach (my office in my coach is ever bit "an office setup")...... where I am lacking is in the WiFi set up..... on the road I've got to react as fast and in the same manner as if I was at home in my office.
Sorry about not including this information.
