Hi,

Could really do with some help:

Setup:

I have 4 deco p9s over a 3 story house. They are connected in ap mode as the p9 doesn't support the fiber connection. I'm using a Vodafone router thg3000. Main deco unit is located next to the router.

Symptoms

Internet will drop out on all devices both wired and WiFi randomly and will sometimes reconnect or need a deco master/full network reboot to fix. The problem has only started in the past few weeks and looks to tie into the latest fw upgrade.

If I connect directly to the Vodafone router either through WiFi or wired the internet connection during an outage the internet is working.

Steps taken so far:

I added some monitoring today to see if I could trace the issue, I have home assistant setup and have setup ping monitoring to all the decos.

You can see from the screenshot nearly all the decos are dropping pings but the master is often going totally offline for a few minutes at a time. In some instances devices on the network show the gateway (Vodafone) router also isn't accessible. But a direct connection to the router works fine.

I have also had Vodafone upgrade my router to latest firmware to rule that out being an issue, but as the internet works when bypassing the Deco's I don't think this is the issue.

I have also swapped out network cable between the main unit and the router. 

Would really appreciate any help possible.
 

Thanks, Chris
