Dropout of video over wifi


(Gwa Gwa) #1

Hi guys,

I have an issue when viewing video in QGC over wifi. Evert ten seconds or so the video drops and I see a garbled grey mess. The video returns to normal after a few second, but dropout is happens consistently. This does not happen through direct ethernet connection.

Things I have tested:

  • I have upgraded the wifi router from a 300Mbps to an AC repeater at 750Mbps
  • I have a solid 70-80Mbps connection up and down when testing in http://192.168.2.2:2770/network
  • I have tried dropping the Frame Rate and Frame Size
  • I have tested on Windows and Mac with top spec computers

None of the above has noticeably improved the situation. I think that it is a timing issue with the low latency video and latency over wifi. Has anyone had similar issues?

Thanks
Chris

The same problem bothers me
same time: about 10s
same problem:a garbled grey mess
I am trying to upgrade the hardware. It seems that this is not useful.

When the curve goes down, the video is lost

I have this seldom on wired ethernet with router.
No internet connection to router.
Often hiding the map (lower left) helps.
Might be QGC trying download and overlay map in my case, but there is no map to get.

Try hiding map in QGC.
Try wired ethernet via router.

Hi, in my case I use a Umbiqity AP and changed my computers WiFi settings to only 20 MHz bandwith. Now it is super stable.
Cheers

I’ll point out that this is not a supported scenario and it is recommended to stick to a wired LAN.

I’ve noticed the same sort of poor performance in my few experiments. I’m not sure what the problem is at this point. But there are some hints in the comments here.
