Are you able to constantly reproduce this issue?

By the way, Did your Deco X50 work in "wireless router mode" or "Access point mode"?

Did a power restart of the whole Mesh help stop this issue?

  @David-TP 

To answer your questions above:  Yes, constantly reproduceable.    DECO X50 is in router mode, ethernet to the modem, ethernet backhauls to the 2 X50 mesh nodes.

Has not been restarted since the FW upgrade.  Next weekly reboot scheduled for early Thursday morning.

I will send the app log today.

Cheers!

  @Nertz56 you might wanna restart the decos first.. and see if the issue still exists. 

@David-TP 

Finally got around to restarting Deco.... some interesting obsvervations made testing device notifications.  I came across this thread relating to a different model but seems to apply here.

Using that procedure i was able to set device notification with the main Deco only powered.   

I cannot however confirm that actual device notifications work as none have yet sent notifications after triggering the condition that should have pushed a notification.

@David-TP 

Waited for 2 hours, and still no notification of device going offline.

So far, able to configure with workaround, but the feature is not working.

I have a mesh home network consisting of 4 Deco X55's which ! auto updated last night and I immediately had trouble with internet speeds. Tried rebooting them all through the app as well as hard reboots by disconnecting power to no avail. I have another backup router for another area of the house which was working fine,so I knew my ISP service was fine.

I Googled the issues and saw a number of people in same boat who did a factory reset of the all of their Deco satellites and said it fixed the problem. I didnt want to do that and saw one thing about making changes in the QoS settings and found that the "Total Bandwidth" was set to 0.1 mbps down and 0.1 mbps up, which is supposed to be total available bandwidth from your ISP. I simply changed both down and up to 1000 and it started working. 

Looks like the firmware update reset the QOS seetings to 0.1Mbps and changing this to 1000 fixed the issue for sure.
