Hello community!
So after watching some videos of the first european models doing range tests, I´ve conclude that the signal range is pretty weak in areas with interference.
It seems to be ok over the sea, and in areas with not a lot of buildings but looks is easy to loose signal under 500m distance.

Im not complainging, since I understand you shouldnt fly this drone much further anyway, but, since Im an absolute novice, I want to fly safe and enjoy.
I dont want to be sacared of buildings, shadows, interference since it seems easy to encounter this signal loss if you go behind trees, or big objects.
So, being Wifi, I thougt... range extenders... I did a little research and there is tons of info on this topic.

Anybody has experience with this?

First a link to a website with plenty of info in this topic regarding DJI drones:
https://unlimitedrone.com/2017/0 ... ut-drone-extenders/

This is a second part of two videos, first one shows the DIY part of the windsurfers, this one shows the tests and results.



By the way I posted this videos before in another post, about someones range test.

Hello and good day Juliflash. Thank you for reaching out. I hope that you will get the best information from our valued DJI co pilots with regards to using a WiFi extender or range extender when flying there drones. Just a friendly reminder that DJI don't recommend using third-party accessories such as the WiFi extender or range extender to our DJI Products as we can not guarantee the outcome of using it. Thank you for your understanding.

Complitely undertandable Mr DJI Stephen, thanks for the answer.
As I said, I still have to check the range myself but I dont want to fly first time and crash my drone for a lost signal or bad RTH situation, so I must take all precautions.

I have to say that the EU range tests I´ve seen are very discouraging, and worst, risky.
At this point, I even thought very seriously about cancelling my orders and wait for updates, and more videos.

But I´m the type of inventor kind of guy, so a little research showed interesting results. An antena booster is nothing that will damage the equipment, is being used for decades, but I understand is a third party product and you cannot advise using it.
Thanks again.

PS: Please ask the tech department to consider checking the EU version for range, maybe a FW may fix the weak recepcion.

Seems kinda risky, im still a new at this all so I think I personally would wait until I got conformable flying before attempting to use any range extensions.

I wouldnt bother. Even my M2P has lost transmission at around 500m in some built up areas. It's normal for Wifi to do that. Just plan your flights more carefully and make sure to have LOS.

Absolutely, I will practice and fly a lot before attempting to go far or behind any object.
I will do some tests though and report here my results.

Well if I had a M2P and loose signal at 500m I would be very insecure.
Maybe the range test is making me look as I am trying to fly really far with the mini, but that´s not my intention, my intention is to increase the strength within a 500m radius.
Once I fly with confidence I will do some tests and report here.

Maybe something can be done software wise to improve CE signal reception in general, so is nice you can forward this info to the tech guys, seems the 2km range promised in Europe is far from achiveable.

Europe amen Italy 2.4 ghz used by a lot device, 5.8 to low mwatt

Not understand while dji with same device same size same weight not do same hardware like spark, very stupid choice a lot of people in Italy are carrying back his model impossible to fly in city, I know is not because people want go at km but if loose video and trasmition signal and Gps not work you have a fly away

I agree here, I have to see what happens where I live but still I want to record other things than trees and open fields. I wold love to know if they are looking in to fixing this.

That's just a draw back of flying in a city .   I should clear a couple city blocks (LOS) even with the strongest interference .
If long range is what your after , take it out to the country or ocean and fly up and away from everything . It should do what DJI says . I saw a video of a guy get 3.4 miles out of one but he was in the desert . Good luck and happy safe flying Juli

The range extenders do work, but we need to keep in mind they direct the signal, so knowing exactly where your quad is with respect to your radio is important.  the small folding gold foil reflectors made to fit the radio for your quad are decent and compact.  they are also only around $15 US

I don't know what to do! My DJI mavic mini is running on 2.4 ghz as well. I'm in the middle of the rice fields, there is no interference of anything here, but it loses it's signal already on 49 meters! Vertical and horizontal.  I also have the Spark and the Spark is doing fine here, I can fly up to 300 meter without losing any Wifi connection. 49 meters is just madness and makes this Mavic Mini useless for me.

Anyone has any advice?

Or try manually change the transmission channel to 5.8Ghz, it will be more stable & less interference.

first advice is to not fly directly above you. Even if you orient your RC antenna parallel to the ground, the drone's antennae are in the front legs, which are vertical. It cannot transmit directly down. Fly your drone away from you before going higher.

Put phone in airplane mode.
Dont use smartwatch if you have one.
Dont fly the drone just straight up, is the worst position for the antennas.

All tried what is advised above, but it doesn't change anything. The Spark, which i use on the same location is working fine and flies up to 300 meters without any lost of wifi connection. The only thing I was not able to do is to change it to 5.8Ghz. It is not available in the app.

Flying with the drone above has the worst signal, try moving it a bit further, let say 100m distance and then ascend.

Not sure about Indonesia law, but in Spain is prohibited to fly above 120m in cities, and only 20m if there are people below or moving vehicles.

Fly safe and have fun!

Having bought the Gold parabolic reflectors for my mini, i can confirm that they DO indeed work quite well..  But as has been stated, it is advisable to continually 'face' where the drone is at all times... Because these reflectors DO make the RF signal more 'directional' ..

What I tried to say fly 300 meter away. With the Mavic Mini I flew 49 meters up and 29 meters away and it already losing it signal. Spark on the same location has no problems at all and can easily reach 300 meters away and 150 meters up. It seems like there is something wrong with this Mavic Mini, or the remote control.

What you do to change to 5.8ghz is to select "manual" in the transmission menu and touch one of the channels from 149-165 (the one with least interference) , this should then change it to 5.8ghz.

Channels 1-13 are 2.4ghz

Tried everything now, put it on manual mode on 2.4ghz and also on 5.8ghz. Changed it with the GPS hack into FCC mode and also back to CE mode (original mode) with the 13 channels to choice from. All doesn't really matter. In FCC mode it allows me to fly a little bit more far, so I reach about 80 meters and then lost connection. Still in the rice fields, no obstructions or other WIFI interference around. Then also tried my Spark again, same time and location. No problem up to 300 meters far. It seems that there is something serious wrong with the Mavic Mini.

Are you using any prop guards or legs etc. the Mini will automatically set "payload" mode which limits you to 30m height and 50m distance.
Also have you turned off "payload" mode in the advanced safety settings menu

Have you ever dropped the RC, this could have dislodged one of the antenna cables

WiFi repeater or extender is used to extend the coverage area of your WiFi network. It works by receiving your existing WiFi signal, amplifying it and then transmitting the boosted signal.

A Wi-Fi extenderincreases the speed limit of your internet by transmitting a strong signal command to the router. With this device, you can connect multiple other devices to the router so that you can enjoy using the internet on your cell phone, tablet, PC, and laptops.

The radio signals connecting DJI aircraft ARE NOT WiFI, they just happen to be on the same frequency. Therefore a WiFi extender will not work.

You need to find a router with a strong transmission signal. It is not very difficult because the world is rapidly evolving with the increasing demand for high-speed Internet connections. But difficulties begin when you need to decide on the choice of the router. I use the site https://freeholidaywifi.com/netgear-c7100v-vs-arris-svg2482ac/ after reading the recommendations you can choose a modem for yourself that will meet your requirements and will work effectively.

Sorry for bumping such an old thread but I am in process of choosing a new wifi range extractor and router. Agree with post above. First, you should better buy a good router and then move to an extractor. By the way. I think that I'll choose the Netgear extractor after reading the recommendations at https://themybuy.com/best-wifi-range-extenders/. I have not heard anything about your extractor but will probably compare. I need to have a very strong signal and a fast connection.
