Before I connected my DJI controller to the tablet, I tapped on my UAV Forecast icon on the Tripltek and was able to access the internet and my location with no problem. I went back to the same exact location 3 days later and my tablet could no longer access the internet. Notably, my tablet has no SIM card nor am I linked to any cell phone company. I shut down the tablet a couple of time and still no internet access. Any guesses here?
