When I first got my P3S I was able to fly out to 600 meters without any obvious signal problems, although I didn't continue further as it was only the second time I had flown it: http://healthydrones.com/main?share=MjQxOQ . Here's another flight out to 200 meters without any signal issues: http://healthydrones.com/main?share=MjU3OA

I sent it in to have the camera replaced as the lens was messed up: http://forum.dji.com/thread-43329-1-1.html

When I got it back there was a new version of the DJI Go app and a new firmware. After completing the firmware update without any apparent problems, I went and flew the P3S in the same location where I previous had no problems and found it was having a terrible time with the 5.8 GHz control uplink signal. The log shows many "Mode changed to WiFi_Reconnect" messages, although I'm not quite certain what that means as the 2.4 GHz wifi downlink stayed rock solid the entire time. The RC signal would bounce between nothing and full randomly even when hovering.

Later I tried a parabolic reflector and was just barely able to reach 1000 meters:

Here are some more flights, I don't remember which ones I was using the reflector with (on some I tried both with and without to test), but even with the reflector it still had problems:

During a POI orbit today it was really acting odd, with the POI mode on the app cycling on and off repeated during the flight. The log is interrupted because the quad flew out of line of sight momentarily as it orbited around a hill. Strangely enough, the log doesn't actually record that!

Well, a few things to keep in mind with the standard line.
They are more of a line of sight type drone versus the upgraded models with the light bridge.
So you have to make sure you have a minimum interference such as other WiFi and obstructions.

So you POI might have issues with the trees and such.
Now then, if you want to increase the range we can provide you with some information, but please note it would void your warrenty on the controller (and maybe also your bird)

LOL, I had to step away from the computer for a few minutes and was just coming back to edit my post to mention that I was keeping the antenna in the correct orientation and understand line of sight issues with UHF radios (I have an amateur radio license.)  

The most recent example was in that last log ( http://healthydrones.com/main?sh ... ENERALNotifications ) at 8:07 in the flight it momentarily loses the RC signal at a range of only 257 meters with clear line of sight. No trees, no power lines, no houses or other interference sources, and again the wifi downlink remained solid, it's only the RC uplink that has an issue. I've checked the controller and the antenna cable seems fine (it's long enough to not bind up tightly as I've seen in other peoples posts about P3S range problems.)

Ah, and I forgot to mention I've relinked the RC and quad several times on separate occasions since this started without any noticeable improvement.

I am so tired of this.  Not of people complaining about the range issue of the Standard. I am one of those people.  The fact that SO MANY people report the EXACT SAME ISSUE and the Dji response is to either check for interference,  check your antenna or return the aircraft to repair.
It is always the same. Someone buys a Standard.  The first few flights are awesome,  better than expected.  User is thrilled. He does a firmware update,  eagerly looking forward to new capabilities.  Then goes for a flight. Now his awesome Standard will not fly as far as a well made paper airplane.
Come on Dji!  I solved my problem by buying an Advanced.  The Advanced is amazing and I am still thrilled with every flight.  But that option is not available to everyone.  The frustration and anger that comes from having something that was great become something useless when all you did was follow manufacturer instructions has certainly cost you customers.  Customers = sales.  Surely you have not become so profitable that you no longer care about increasing profits.  Throw your Standard customers a bone.  At least have someone actually look into the range problem.  It MUST BE firmware related.  There are to many examples of people saying the same thing for it to be otherwise.  The OP of this post says he is a Ham radio guy.  He certainly knows how RF works.  I am an RF tech with over 30 years in the field.  I also know a little something about the subject.  And many other Standard owners have reported similar technical experience.  Recognize,  accept and acknowledge that there is a problem at least,  rather than give the same old tired useless response we have been getting.  I, for one,  and I am surely not alone,  would be glad to provide whatever assistance I can to help.  Because,  as many of us are technical people,  a lot of us have taken steps to increase the range that voided our warranty.  We would probably have done those things anyway,  but doing it closes the door on Dji fixing it without charging almost as much as just buying a new drone.  No one wants to return the drone as a first option,  because we enjoy it so much we don't want to be without it for the time it takes to repair and return it.  So we try doing it ourselves.  Actually,  it is a testament to the construction of the Standard that we fail to fix the problem.  As a tech,  I know that 90 percent of the repairs I have done have been cold solder joints or related.  Of the remaining repairs I have done,  90 percent of them are capacitor related.  And since I could not find either of those issues in the P3 Standard,  I must conclude that it is well made.    I must also conclude that the problem is almost certainly FIRMWARE related.
So,  how about it Dji.  Give us some love.

*BUMP*

Anyone from DJI able to comment on what the "Mode changed to WiFi_Reconnect" messages actually mean?

Don't count on it.  The Standard is like the disabled cousin no one wants to talk about.

i guess their DJI Go app don't understand their firmware.
Try Litchi app to fly it.

Has nothing at all to do with the App. All Phantom 3 aircraft will fly with no app at all.  You can fly them with no device at all.  You just will have no fpv view or control of some parameter limits.

After updating the P3S firmware to 1.5.70 and the DJI GO app to 2.7.2 it would seem I'm getting an even WORSE signal, which makes me wonder if it's actually the firmware or if it's a hardware failure that's degrading over time. I tried with both the DJI GO and Litchi apps:

GO: http://healthydrones.com/main?share=plKxAJ
Litchi: http://healthydrones.com/main?share=IRFZGu
Litchi: http://healthydrones.com/main?share=KVUNHP
GO: http://healthydrones.com/main?share=aqVDWq

I re-linked the RC before the flight (figured that was a good idea after the firmware update,) and once more after the first flight as it was having so much trouble with the RC signal. I had performed a cold IMU calibration after doing the firmware update yesterday, and calibrated the compass before the flight (again I figured it was good idea to do both after a firmware update.)

Time to start the RMA process I guess...

I just got a generic response back from support that shows they clearly didn't read my inital email and included instructions that don't even apply to the Phantom 3 Standard: "Please lower the transmission bitrate in the Image Transmission Settings and choose custom. Then go to an area with no interference" and a picture showing how to orient the antennas on a Lightbridge P3 controller, and then they marked the ticket as resolved!

I sent a reply indicated the problem has NOT been resolved, this is not very encouraging at all.

Any progress in this? I bought P3S about two weeks ago, it was amazing-flying super far, working fine with my Iphone 5c then I updated to 2.7.2(stupid me, last time I updated GOpro 3 black ti fucked up and didnt work again, bye 500$)since then I can fly about 30m straight up, when I try to move the drone sideways or whatever I keep loosing signal, drone keeps RTH. Now it nearly landed in a trees. Im so pissed off. I promise I will never do an update again.

I contacted technical support, they kept telling me iPhone 5c is not recommended device and to downgrade the same way I upgraded. Obv this doesnt work as there is no update nor downgrade button in DJIGo app. Then that fella apologized that he realized I cannot downgrade P3S. and basically told me to get a new phone. DAFUQ.

million dollar question: how to downgrade? pretty please.

Im now travelling New Zealand so I cant just send it back as I have no permanent address. And I obv dont want to return it and wait forever to get it back....

Got it back yesterday and took it for a couple flights today. I managed to get it out to 1702 meters on my first flight ( http://healthydrones.com/main?share=HHbbfj ) and 1884 on my second ( http://healthydrones.com/main?share=TClAfp ),  so I'm happy. Once the warranty runs out on the RC I'll probably replace the 5.8 GHz dipole antenna with an inexpensive patch antenna like this one: http://www.hobbyking.com/hobbyki ... ntenna_RP_SMA_.html

Oh, and in case you're still wondering how to downgrade, you press and HOLD the "school" icon (the one on the top right on the main DJI GO page.)

Hi

I think i have a similar problem... http://forum.dji.com/thread-62932-1-1.html
But with a difference... my PS3 was flying ok... till 3-09-2016
nothing append that day... next flight i begin to have this problemns....

If you read the above post will see that i have there a 2km flight.....

How did they fix it? do you know what they did?
