Deco P9 unstable connection
Hi
I've had a 3 unit Deco P9 system from February this year. The Deco is in router mode.All units are connected directly to mains, no extension cords are used. Main unit and one of the satellites are located about 10m from each other and only one thin wall between them. The third unit is in the basement of my house and there's a lot of concrete, steel and water pipes (for heating) between the units. The wifi connection to the third unit is very weak, but it does exist. Thats why i wanted a PLC backhaul.
The system has been up and running for about 6 months without any issues. Connection also from the 3 rd.unit in the basement has been fast and stable, enabling remote working and video conferencing.
Suddenly about a week ago problems appreared. I did not change anything. Connection from the basement unit us unbelieavable unreliable.This applies to both wired and wireless devices. Sometimes the connection is as it used to be, but suddenly it is lost, or it is extremely slow (Speedtest showing less that 0,1 Mbps download speed). At the same time connection from the other 2 units is as always, i.e. no problems at all.
When the connection is slow, the led of the unit is solid white. It might also be solid white when there's no connection at all (Windows PC with ethernet cable connected to the unit does not recognize the connection, but white led anyway). And also, there has been times when there's no connection and the led is blinking red.
When the connection is slow, it seems that at least half of the packets are lost when pinging Deco's IP.
The firmware is the latest.
I have tried everything I have found from this forum and elsewhere. I have resetted the whole system, swapped the places of the units, tried fixed IP addresses, removed QoS services etc. In any case there's unstable connection from the unit in the basements and the others are working fine. Could it be so that deco wants to use the very weak wifi backhaul, even though the PLC backhaul is available and the PLC icon is visible in the app? But, I didn't update the firmware and before this week it worked fine. Is the Deco updating itself automatically?
I'm desperate because I need the connection for remote working. I already renovated my old office room and it's now reserved for other use. It's very difficult to carry everything back upstairs.It also will be very difficult to have an ethernet backhaul to the basement.
I paid over 200€ for the system. Now it's 6 months old and it probably will be difficult to get my money back.
Please advise.

Hi,
Sorry for digging this topic, but I also have a 3 unit Deco P9 system, and it's getting to a point where I'm thinking of replacing the system with a different vendor. I'm full-time remote worker (as most of us these days) and it's really annoying to be in the middle of a call and the connection starts dropping...
So I have setup a constant ping connection into by default gateway and also a random public website, and randomly throughout the day I lose connection to the gateway, meaning no Internet, nothing. The drops are for a couple of seconds and the connection normalize after a couple of minutes or seconds, it depends. Everything is so random, no specific times of the day or longevity of the drops or instability. I have tried with 2 different laptops, so the issue isn't the device. I have the Deco unit 2 meters from me...
I have tried to change the Deco units to different wall sockets, restarts, etc, etc no improvement.
My system is configured in router mode, IPv6 disabled, no QOS settings, etc, etc, etc running on Firware 1.1.3 Build 20201228 Rel. 55057.
Don't know what else to do here to be honest. I didn't try to connect an ethernet cable directly from the Deco unit to the laptop and see if there are any improvements, but as I said... 1 2 meters from the unit...
