having problems with my DJI mavic air it has small video transmission signal range, I've seen many reviews of this drone reaching more than 500m but sadly mine doesn't. Already updated and even refreshed the firmware of the drone and remote, also tried different wifi channels like 2.4ghz and 5.8ghz, also tried going on a isolated area away from interference on signal but still has little range, on a small town drone could only fly max of 90m and on isolated mountain only 400m. i have not tried using a range booster because i believe the stock mavic air can fly easily over 1000m. Already tried moving away from objects that can interfere with the signal, also did properly place the antenna and also using a phone with no sim. (USING THE DJI CONTROLLER)
