Hi
Using my MINI SE for 2 years now and I love it, but in Urban or city area, wifi is disturb or unstable.
Would like to extend power of wifi or reduce my interferences

Any tips or material to help me ?

Thanks in advance

Hi there. We do apologize for the trouble. Have you tried to test flights in different locations? Please follow the proper antenna orientation on the image above then check if the issue persists. We do not recommend installing any third-party range extender for flight safety. Thank you for your valued support.

You already have good experience, but you won’t be able to improve the connection on the Mini 2 SE.
Listen to the advice - switch to Mini 4, it's simply the best drone in terms of communication and video quality)
