@David-TP It doesn't matter to where the the other satellites are connected to or not. All my M9 are connected to my main M9 via Ethernet, also all of my m5s are connect through Ethernet except one. my X50-outdoor will never connect to the preferred M9, the closest. All many others here are experiencing. It's just your R&D whom cannot reproduce. It's a pity.

  @David-TP Hi,

The powerline models are AV600.

The app is inconsistent. Sometimes it reports everything is fine but within a few seconds it then says the main deco isn't working.  Sometimes it reports some of the satellites as not working, but I can click and see connected clients. I emphasise that the wifi appears to be working perfectly now from a user's POV. 

I think it is probably a problem with the Decos reporting to the App correctly, which may be a QoS bug.

  @David-TP I could be wrong but my understanding is that QoS packets are used to monitor and manage network traffic and so the Deco app is probably using them to generate its maps and manage the devices. Plus I note that a QoS fix was the only change in the latest firmware update.

The wifi continues to work well by the way, the app continues to report that the network is not functioning (apparently incorrectly).

Hi @David-TP! 

Have an X10 and 2 M9Plus Decos in the above configuration. Early this week, there was new firmware released for both devices and they've all been upgraded to the latest firmware version, see images for version number.

However, since the upgrade, none of the clients (except two) are showing up in the client's list on the Deco Android app, either on the main all clients list or the individual Deco client list. The clients are connected though, and are getting Internet service as normal.

They do show up when connected to the main Deco through the Web interface though, so it's clear the Deco is recognising them.

Have tried rebooting and even turning off and on the WiFi on individual clients but they do not display on the client list.

Is this a bug in the new firmware and is there a fix for it? Or is it an incompatibility with the Deco Android app quick still be fixed soon?

  @David-TP This beta solved my problem with the X50-Outdoor not connecting to device set in "Connection Preference" on the X50-Outdoor. Now it connects to the m9 that I have selcted! Thanks a bunch for this!
