Before downloading the Deco log, I decided to reboot the camera and Decos for a "clean" test. I did several tests and I could not re-produce the camera problem. I tried to force it to change the Deco and it worked without problem. Either it's a camera bug or a firmware bug. If it happens later I'll tell you about it.
I still leave the brand and model: SriHome Model SH038.

I could check the log of the main Deco and I see several errors like "daemon.err nrd[18636]: wlanifMapToBandwidth: Invalid bandwidth from driver: 3" all the time. I restarted several times the Decos and the modem/router of the provider and this problem persists (attached 3 logs in different time).
I put another router that I have at home, replacing the Deco X50 model TP-Link Archer AX50 and this error does not appear.
My provider gave me a Huawei Echolife HG8247H5 modem router. This equipment is configured in bridge mode.
What is your opinion about this? 

Answering another question that @David-TP asked me: if there is no alert on the smartphone screen, will you see any notifications in the Message box on the APP?.
The answer is yes. That is, when I use the X50 Decos I don't get a popup while the app is running in background, but if I open it, I see the message that a new device connected to my network.
This does not happen if I use the Deco M5. The message with the app in background comes ok. It's weird because the cell phone and the app is the same.

Thanks!

  @David-TP Hi David,

I have the exact same issue that @xplodzs faced.

After updating my 3 units of Deco X50 to the latest version (1.1.0) the ethernet connection keeps disconnecting from the main deco to the satellites.

The 3 of them are connected in router mode via ethernet. My wifi is set as 2.4/5Ghz and it worked flawlessly before the update of the APP to the v3.0 and the firmware of the decos.

I have reviewed the logs and the error wlanifMapToBandwidth: Invalid bandwidth from driver: 3 is getting repeated over and over again.

Indeed I am just 2 meters away from one wired Deco.

Do you have any idea of what could be causing this? Should I factory reset all the Decos?

When is the update coming to x60 which is by the way a more superior model than x50? Cant believe we're treated this way.

  @David-TP

Is this a manual update as just got the X50 triple pack and it says when checking that the firmware is upto date, but its on 1.0.8 Build 20220407 Rel. 69134

  @David-TP Thanks, I've manually updated and this has resolved my network speed issues across all devices, now get my full 330/50 internet speed, so hoping when switch to 1Gb internet i won't see any issues

@David-TP. Can this firmware update will be available at the end of this year or will rollout next year?

  @MarleMore you can install manually, by downloading the update, unzipping it, then update via the web interface
