I bought tello something like two weeks ago and after week i bought mi wifi extender. And i using tello with it and i still have poor (max 15 meters) signal. Im using tello with Tellofpv app. Can anyone help me. And i still have wrote on screen WIFI INTERFERENCE.
We have found both the DJI Tello and DJI Mavic Mini have WiFi interference problems, so that sometime in a gym we can only get three of six flying. We had to learn alot about WiFi 8011.n protocols. To evaluate the signal strength, channels, etc. Not an easy task. Takes a while to learn. See our videos on youtube channel mecatx. Some may help you. Recommend using wifiinfoview to understand the area problem and try to solve it. sometimes finding a better channel will help, not sure you can do that with the extender. Probably can do that with a cheap WiFi router. Good Luck.
