I’m using CS but getting warning also, it does go away but can return regularly I have tried with iPad and I don’t see the warning so am a bit confused is it aircraft problem or CS problem or in your case monitor or aircraft, I think it needs to be corrected in new firmware. It’s very disconcerting.

I agree it is disconcerting as I am not sure what is causing it. A lot of the time when I am flying, I am watching the drone and don't realise just how many warnings there actually are until I upload my flights to Airdata where the  majority of the flight is just full of the warnings.

KerryG Posted at 2017-12-8 08:39
Have you actually tried 5.8? I have done 3 mile flights on 5.8 with no issues when I was getting interference issues on 2.4.

I have used 5.8ghz some time ago but haven't tried it recently because it shows no bars after about 100 mts. I will try it again to see if it has the warnings as well.

Aardvark Posted at 2017-12-8 15:17
Looks like the increased radio interference warnings are part of the V4.1.18 build of DJI Go 4 (maybe even prior to that ? ).

I have gone through my records from Air Data and prior to 4.1.18 I can't find this warning even once.
So for me it only started after this update. I'm running an iPad Air 2 and have tried airplane mode with no
change. 4.1.18 seems to be the real issue here.

Jenee 2 Posted at 2017-12-7 17:45
Yes I do, but 5.8ghz doesn't have the range of 2.4ghz and I am flying out in the country, no houses, no towers etc so the 2.4 band should be relatively clear.

True, the lower the frequency the greater the range. I get the notice once in a while and switch up to 5.8 and the warning will go away. Not a big deal as I keep mine within sight.

Thanks! What a great forum. I learn something from here everyday!!!!

Solved "strong wireless interference"

Hi guys. I solved my very tedious problem with "strong wireless interference". Actually I had this problem, but I think is the same for all the others guys, with my Inspire 1.

First of all I think the problem is not the RC firmware or Drone firmware. Is the DJI Go app. I rolled back to a previous version my DJI GO app on my iPad Mini2 and the problem is gone. With the last software update DJI done some mistakes because is unbelievable that everything was fine months ago. I tried to downgrade RC firmware but nothing. Tried to other devices but the problem still there. Finally I was able to install previous version of DJI Go app and yes everything now is perfect. No more strong interference and the video is very fluid.

Can you please inform us how to go back to the previous version of the DJI Go app please? I didn't think that was possible.

I always have the same issue.  I can be in the middle of nowhere, no homes.  My phone is on Airplane mode and I cannot use 2.4.  I always have to fly in 5.8.

I have the Phantom 4 Pro Plus, took it outside just to test the signal.  Had Strong WiFi interference and then turned off the WiFi in the controller and those warnings do go away.  Is it just that simple?  Kind of excited that can be it.  But 5.8 worked really well for me as well.  Farthest I have actually gone was 3500 feet.  Always seems to be windy here, so do not go too far.

It would  be helpful to see DJI comment on these observations. Such notifications in the app makes the pilot feel that his mission is at risk, which actually may not be the case.
Another  observation from this thread is that the messages or notifications are seen no matter whether you are flying P3S or other P4P

I have to agree with you as I had the same issues. On my original P4Pro the 5.8ghz didn't work at all and I did not realise it had issues until the phantom was replaced because of a camera issue. The replacement worked fine for a while on 2.4 but then I had issues so switched to 5.8ghz and no problems since.

Just a follow up, I have the Phantom 4 Pro Plus.  I turned off the WiFi in the controller and flew 2.4 this time with not one issue or warning.  So happy now.  I downloaded a 3rd party app to record the controller and completely forgot to use it.  Tomorrow hopefully.

All the high tech talk aside, I've been getting these errors/warnings since day one with my P4P (Sep this year) and it does not matter where I fly.  All with earlier versions of the GO4 app up till now, it has gotten to the point that I'm ignoring them although they concern me still.  I've had my devices turned off, airplane, etc. nothing seems to stop them.  If there is a reason I'd like to know but it is going to take more than guessing from what I see about this issue.  I find it interesting that the Mavic is OK but the Phantom is not...there is likely a good technical clue there but none of the advice so far has had the desired effect.  While I don't know for sure, I am chalking it up to the app or an overly sensitive frequency monitor, but as I said it bothers me when I see these.

DJI have no clue as to how to correct these issues.  They create them to keep us distracted.  I get these warnings from day one, and now, with the latest update, I am unable to fly on my farm which is nowhere near anything.  DJI need to address these issues before a lawsuit is initiated.

You have a incompatible RC firmware version installed !
I believe that you update AC firmware, but don't update RC firmware...
That problem is easy to solve :-)

No! I update first RC! AC is with .602

Restore factory defaults first
Update your RC with SDcard to version 1.2.0.0 or 12.2.0

I solved mine.  Your controller is picking up wifi signals.  Turn off wifi in your controller and you will never receive those warnings again.  I can now fly at 2.4g with no issues.

I don't really understand what you are saying. It is not possible to turn off wifi on the standard P4Pro RC. Are you referring to the P4Pro+ RC with the screen or are you referring to the phone/tablet?

Yes, the Phantom 4 Pro Plus.  Turn off wifi and no more wifi interference.  I am sure you can do the same thing with a tablet.

OK I can understand that because the 2.4 ghz band is so widely used, it probably is prone to interference.  I often fly on a farm well away from town and houses but had constant problems with 2.4 which I could not understand. Turns out the farm has installed pumps, waterers, hands free tractors and other automation all on the 2.4 band.  I stay on 5.8ghz and don't have any issue at all now.

Nothing unusual about that. DJI do not have technical people manning this forum.

Mods may not be, but some of the Admin are quite well DJI educated...

This is why you'll never want to upgrade even if there is extra features. When it's working leave it alone! LOL

As the telecom wireless network(4G network) use 2.4 GHz wireless frequency for coverage and transmission, the wireless signal interference to the drone on 2.4 GHz can be quite severe in some certain area  where some base stations or transmission equipment nearby. This kind of warning message pops out just to remind the pilot for flight safety, instead of product defect. No worries.

You say no worries, I do construction documentation with an Inspire 2. They all seem to have powerful routers all working on 2.4 and they wreak havoc with my mini 4 tablet, I have also tried my Galaxy tablet and it is worse.
I'm just wondering what rocket scientist put drones on the same frequencies as cell phones and wireless networks. I need to put the channel on auto and then the it constantly is searching for a clear connection increasing the video response delay. Try shooting panos when that is going on. When I do mapping I constantly lose the video feed, fortunately it doesn't affect Drone Deploys mapping photographs.
I would love to find a fix for this but as long as we are forced to share that bandwidth I think we are going to have problems.

We share a common section of the radio band with countless other non-critical transmitting devices, and it is the same all over the world. Nothing is going to change that, you have to learn to live with it.

I'm flying the Inspire 2. My primary use is construction documentation and most job site have powerful routers that drives my video link crazy at times. To the point I lose my video feed completely.
I use Drone Deploy for mapping and Litchi for waypoint flights. I have found that as long as I turn WiFi off and do not use Custom communications setting I seem to have fewer problems.
I use the mini 4 tablet and it isn't used for anything else. Also I turn my cell phone off while flying, not sure if that makes any difference or not.
What amazes me is with Drone Deploy if I lose the video feet it is still linked to the transmitter and continues to fly the mission, same with Litchi and waypoint flights.
I have found that using Litchi I have fewer interference issues than I do with DJI app.
What amazes me is why the FCC would put our drones on the same frequency as cell towers and routers.

It has nothing to do with the FCC 'putting' anyone on a specific frequency. The band is a general catch-all for all non-essential radio communications world-wide.

I must disagree, it does have a lot to do with the FCC because there are many frequencies that could be dedicated to drone operations other than 2.4 and 5.8.  I have some experience with ECM gear so I do know a little about what is available but we are not allowed to use. What the rest of the world does isn't my concern, it is what we have here in the US.

Yes, a communist country telling us what we can and can't do.
My point is it would be easy for the FCC to give the  US drone operators frequencies with little of no interference. Once given the frequencies it would be easy to convert the drone and transmitter over to the new frequencies, oh, and eliminate geo fence while we're at it.
My point about not caring what the rest of the world is doing was only in reference to drone operations. So do you have any constructive comments?

You call cell phones and routers non essential communications.

For a start, cell phones are not on the same frequency band as the aircraft, and WiFi routers are not considered essential communications, but don't let your ignorance stand in the way of a good rant....
