Hello,

For the last couple of months we have had problems with our Deco P7 system.

Our setup had been like below since we installed it in early 2019. ISP modem on the ground floor (Wi-Fi off), hardwired to Deco 1 and Deco 2 on respectively ground floor and first floor. Deco 3 in the attic, with Wi-Fi and power line connection. This was working fine until a few months ago.

One day our internet completely cut out and no amount of resetting devices brought it back up. Initially I though it was the ISP’s problem, but after hours of trial and error I found the problem to be with the Deco’s. We suspect the Deco firmware had just been upgraded.

When we disconnected the internet cable from either Deco 1 or Deco 2, internet would come back again. Plug the cable back in and internet would immediately go down again. So the result is that we can now only have one Deco hardwired, which is not what we want.

We have tried swapping all three units around. Location does not matter. Which device is hardwired second does not matter. Everything crashes when a second cable is connected.

All Deco devices have firmware version 1.4.2 Build 20200408 Rel. 73944. No upgrades have been available since this issue started.

These are the log files for when we plug in a second cable.
