WiFiRanger has never concealed the fact that it uses FCC-certified hardware produced by a number of companies. WiFiRanger's value-added is the firmware (the proprietary software) we’ve embedded into those off-the-shelf devices. WiFiRanger's firmware means that you don’t have to know anything about networks in order to have a one up and running in your RV in a matter of minutes. All WiFiRanger routers are plug-and-play and have an easily accessible on-screen control panel. WiFiRanger's firmware represents the culmination of over 6 years of effort by its staff. Sure, you’re welcome to build your own, if you have the time and talent!
