If you go to a computer store you can get a modem installed... Sometimes theres modems on the motherboard but theyre usually pretty shit.

If its fairly new it should have a modem already.. depending on how much it costs..

The modem needs to be wireless if you want to have portable internet.. then you'll have to find places with wireless internet routers and whatnot..

If you want to have internet just at home, get an external modem and just plug the network cable in... Im assuming you've already got a computer with internet access since you're on RV.. So unplug the network cable from that and plug it into your laptop..
