I have an intermittent issue with WIFI on the Galaxy RVR. It is not range related, as it occurs as I follow the rover when using the direct link (phone connected to WIFI on the rover). I never get more than two feet from the unit. The signal just drops and the app freezes. There is not longer an RVR connection available. I have had it run quite a good distance, and the same thing happened so debugging it established it is not a range problem; the wireless just seems to shut down. I double checked all connections, it does not seem to happen as a result of being jostled or going over a bump - it just happens. Is there a way to debug the wireless connection (eg logging) while it is in use?
Maybe try with this post
