I'm not a big fan of RV parks WiFi. Usually even if they have a strong WiFi signal the Bandwidth of the "pipe" they use to connect their network to the internet just is not big enough to handle how mny devices want to connect through from the campground.
I've been fortunate so far to use WiFi sparingly, and rely on my smartphome as a hotspot when I need to connect to work.
Not in my RV - but for a few non-profits I work with I've set up EnGenuis Bridge from a WiFi point - to the EnGenius - to a Wifi Access Point. I've considered do this for RoadAbode. Just is not a priority for our RV Lifestyle right now because what we do - works. Maybe in the Future. Anyway here's the EnGenius I'm taking about
EnGenius Technologies Long Range 11n 2.4GHz Wireless Bridge/Access Point (ENH202) Maybe that would help?
