Our RV is stored 2 blocks from our home with lots of trees and other houses in between. Rather than pay $50 a month for a separate Internet connection at the storage area, I bought a Uqiquiti Titanium Bullet M5 for $85 at Amazon, added a $23 Engenious 8db antenna and installed them at the top of our rear ladder. The Bullet has a wired ethernet interface into the coach and that is what I used to configure the Bullet. On a scan it came up with two pages of WiFi systems and among them was the one that sits in a downstairs window at our house. I got it to associate with that and ever since then I've had the Internet at the motor home. I installed an access point (not a router!) inside the RV for laptops and tablets. An access point simply acts like a wireless hub to connected WiFi devices to a wired network; all devices get their IP addresses from the Bullet.
Have not yet used it on the road but it's nice to be able to check email on a tablet when I'm working (or napping) at the motor home (we have 50-amp service there for the RV).
I also have a Raspberry Pi ($36 micro computer) running Linux that is installed in the bedroom using the HDTV as a monitor. My plans are to set up temperature and voltage monitors on a little web page at the RV so I can check them from home (or wherever). :)
