Deco P9 unstable connection
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
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.

I'm just about to setup a set of P9's for my old man after the one mesh extenders i bought didn't work so well (old farmhouse, thick walls). I'm hoping the PLC works nicely!
Having read this thread i don't think i'll be updating the firmware until there is consensus the new firmware is working well!

@Jaytea What was the temporary fix? I'd like to try it because we have random drops and "Not connected to the internet" from multiple devices every day. I spent a lot investing in Deco for my home and I'm beginning to wonder if I should have tried something else. Really frustrating during this time when we have important distant work and school happening from home.

An update from me... I had contact with TP-Link engineer about a month ago. We had a remote session (about 2 hours) and he investigated my Decos.He found something, did a temporary fix and said they are working on a permanent solution.
After that I've had no problems at all.
Now there's an update available for my Decos but I have not updated yet. Maybe I should contact the same engineer and ask if I should perform the update or not.

@HarlanPepper i have exactly the same issue and can not understand why fixing this issue is taking so long.. we all bought "premium" mesh router with discs but i have to reboot my system on a daily bases to make it function again...
i am also very curious what kind of fix the engineer did!

Since everyone mention tv devices, there is a 'hiddenish' setting in web interface, under Advanced > System > System Parameters > IGMP Feature. Try enabling it.

@levo what does the feature do?

Hi, @levo. What benefit does that feature provide?

@Dre84 It's probably for IGMP snooping, which sends multicast packets only to a specific device.

I have no idea. I installed Teamviewer to my laptop and allowed remote control to the Tp-Link engineer - trusting it really was a TP-Link engineer and not a criminal
. Using my laptop he connected directly to the Deco units using some kind of admin interface or something else very engineery. Most of the time there were two of them and they used a lot of time to analyze the problem.When they had identified the problem, they did something to fix the problem. Whatever it was, it certainly wasn't anything possible for us normal users.
I think you should post a detailed description of your problem and add a @-notification for TP-Link. Ask them if you could have the same fix I have. Or maybe it's already available as beta firmware you could install yourself without the engineer accessing your Decos.
