Hi all. There are a few strange things happening with my Deco system. The connection between my X50s is unstable and drops frequently for a few seconds at a time. I can't tell if this is an app issue or hardware/firmware issue. However, I have some funny things going on in the app so I want to start there in the hope that if I can get that sorted it will be easier to troubleshoot.

Topology: 

• ISP Modem --CAT6-- Deco X50 (Living Room, Main) --CAT6-- Deco X50 (Office)

The two Deco X50s are connected via ethernet backhaul. Both are hardware v1.0 and updated with the latest firmware (1.8.0 Build 25102213 Rel. 43970). The main Living Room Deco is also connected to an RE550 extender in wireless EasyMesh mode, which works fine.

Issues:

1. Even when I have a stable, fast connection between the Deco units, the Deco app almost always shows the Office Deco to be offline. The light on the unit itself is green, but I can't manage the device, reboot or troubleshoot via the app. How can I solve this?
2. When the Decos were connected wirelessly, I had a green wifi symbol above the link. When I first connected via ethernet backhaul, this was replaced with a blue cable symbol, as expected. However, now there is no symbol. When the units show as connected in the app (rarely) there is still a green pulsing line, but nothing to suggest how the Decos are connected. The symbol would be useful to help me see if the backhaul link is having issues and the Decos are falling back to wireless connection. Is there a way to force them to only connect via ethernet?
3. All the devices that are connected wirelessly to the office Deco display in the app as if they are connected (via wired connection) to the Living Room Deco. Even if the two Decos are connected via ethernet backhaul, surely the devices connected to the Office Deco should show as wireless connections to that unit? 

Things I've tried (but didn't work):

• Downloaded the Beta app via TestFlight
• Uninstalled and reinstalled the app
• Rebooted the whole network, in order and in separate parts to try and isolate the issue
• Updated firmware
• Moved Decos out of wireless range of each other (to try and force backhaul)
• Disabled / changed various app settings (fast roaming, beamforming, auto-switch LAN/WAN etc.)

It's difficult to troubleshoot these issues when they all may be connected or causing each other. Advice on how to approach would be appreciated. Thanks!
