I installed a brand new Deco P9 (3pack) 2 days ago and it worked fine until today, when it suddenly lost internet connection. The WiFi was still working and my router did not show any issues except for the LED of the specific ethernet Port, to which the main Deco unit was connected, was not flashing.
I restarted all Deco units, checked with different cables and even tried to setup a completely new network by using the APP. It did not solve the problem until I replaced the initial main unit with one of the other two. This actually did the trick, and I was able to setup the compete WiFi network again.
However, connecting the initial main unit, now as the last unit, didn't go as smooth as before. When it did connect, I decided to test the 2 ethernet ports of this unit by connecting my laptop to them. It appeared that Port 2 is still working, but Port 1 is not detected by my laptop.
Considering Port 1 was actually connected to my router before, this actually should explain for the loss of the internet connection.
Please advice what to do next? Is my unit showing a hardware defect and should I enquire for a replacement? Or is this due to a software issue?
