If your wi-fi not working properly. First of all reboot the router and again check it. if you have face same problem then check setting part.
May it is occur due to system infected by antivirus or malware so contact Avast Customer Service. they will assit you.

mavic air djigo4 rc fly radius 500-1000feet experiences strong aircraft interference in any community park flown. accompanying are both signal lost and signal weak antenna please correct orientation.
when honolulu sleeps, risk flights darkness achieves enlarged radius.
but 500-1000feet radius is wrong considering perfection 4km radius

It absolutely is wifi, it is a 5mhz quarter rate Atheros specific configuration using Ad-hoc connection and a random key. https://wiki.freebsd.org/dev/ath_hal%284%29/HalfQuarterRate You'll find that the Spark, Air, and Mini series with "Enhanced Wifi" all use this chipset, and this quarter rate support.

ath6kl_sdio.ko is used on the MiniSE for example. On older drones ath6kl_usb.ko was used as mentioned here: https://approveddronepilots.co.uk/wp-content/uploads/2018/05/Anatomy-of-DJI-Drone-ID-Implementation1.pdf

If it wasn't WiFI, it wouldn't have been added to kismet.

I did some reasoning for Wifi used by the Spark here: https://grumpylittleengineer.blogspot.de/2018/01/dji-spark-wi-fi-dropouts-speculating-on.html
And the why is mainly because of the high resolution video stream that comes with the RC control connection. I can agree that naming it Wifi might confuse most of the people but it is roughly what is used in the background. The fact is that you need quite the performant transmission system to broadcast high resolution video over a wireless connection. And without re-inventing the wheel there is no real option but to use an broadband OFDM system (this is the physical layer transmission medium access method which basically describes the waveform that is used in the transmission signal  And its what Wifi is using nowadays. And also LTE/4G btw. Together with the frequency bands 2.4 GHz and 5(.8) GHz this more or less characterizes Wifi. (strictly speaking Wifi - or more detailed WLAN IEEE 802.11 - is a bit more since it does also contains a lot of things above the physical layer).
So what DJI might have done is to create a new protocol for video / control information so it fits there needs. But they do that on the back of the Wifi / WLAN infrastructure reusing the already existing and cheap electronics for that, just because developing a completly new transmission system including the electronics for that is just so expensive that their Drones would cost at least ten times as much.

I was under the impression they were using wifi chip sets under clocked so they would have a better S/N ratio with much better range But lower bit rates.
It is wifi
