If your main Deco is flashing red then the intenret connection is dropping which explains why no matter how many Decos you have it still drops.

Look at your modem system logs, if you have critical 3 errors, that is what is causing it.

I am having the same issue with the P9 system I put in my parent's house. It worked great for a week, but now it seems to need a reset every day. I get internet acccess at the main Deco but when I am connected to the satelites I get no internet connection. My P9s are probably using the powerline as the backbone due to the design of their house but there is so little information about the status of the system in the App that I really have no idea.  I'm disappointed in this P9 system compared to my M5 system that has been flawless for me. the M5 system also has a much more robust App with a lot more information. I was hoping this system would be reliable. I can't have an unreliable system in my parent's house becuase I am not there to reboot their Deco every day.

I'm hoping this can be fixed quickly because this is unacceptable performance.

Disregarding the 'tech help' above that has not actually addressed the issue - i dont think my post was actually read!

I contacted their phone support and they advised me a few things (not sure if true or not) that aren't made clear in any set up instructions

• signal is weak in vertical lines
• decos should be placed at extreme sides of the property if possible
• Often too many units cause signal disruption

I spent another couple of hours in the evening trying to sort, and today - touch wood- there has been no dropping of signal, with reasonable speed and signal on every floor.

I went back to using 1x p9 as the main wired unit, and 1x p7 on each floor, placed as far as is feasible horizontally from the ont on the floor above/below it

Depending on the house layout, i would try something similar, as i've had the most success with the units further apart, rather than closer together.

If that doesnt work - I would return the prouct and invest in the google wifi system which seems to have superior reviews (but check out if it suits your requirements). What I've learnt from TP Link products is that they are very simple to 'set up' but not of high quality- the amount of posts on here i've read through where firmware updates are promised by staff that just dont appear is countless. It seems like the products have potential, but that's it.

Good luck.

The house is single story so I can't do multiple levels. The main unit is at one extreme side of the house which makes using wireless backbone less than ideal. It's also a very large home so I have 6 units spread out over a very large distance which is why I was relying on the powerline. I get about 50mbit at each unit when it is working which is the same as when I had separate powerline extenders throughout the house. Those were separate networks which was annoying. This solution is great when it works. It worked great for the first week and now needs reseting on a daily basis so the satelite units maintain internet connectivity. All lights are white on the satelite units and the main unit. I've toggled the setting for fast roaming and that does't seem to do much. I really don't notice any difference either way. Other than that there are not very many options in the App.

I'm very happy with the m5 system I have in my own home so I'm hoping these units are similar. I'm hoping this thread helps them fix their firmware. It's possible I can run a single ethernet line to make one of the far units operate on an ethernet backbone but the reality of today's lockdown make that more of a longer term solution and an expensive one since I would probably get a handyman to do the work for my parents. I'm done crawling around under the subfloor.
