What your talking about is a wifi booster. If you think about it RV's are sheathed in aluminum and metal all of which block rf signals. So an external antenna is the key. I bought a hawkings smart repeater router and connected it to a hawkings wifi antennae on the roof. As long as the CG has a good wifi setup, I have full signal.
