@TP-Link_Deco , what i don't understand is that when i use a tp-powerline adaptor it works without issues, but when i put in the P7 (which includes a powerline setup) it seems to be requiring to be picking up the wifi from an other Deco system, meaning it seems to ignore the powerline capability to setup a network ?

I am wondering if the powerline actually is doing anything.. if i get closer to one of my other deco's (but still very far away), it connects but it gives me a 2Mbps, the green light indicating it has a powerline connection keeps green at all times but does not seem to increase speed,

thx for your support,

Leon.

@TP-Link_Deco ,

That works, but i was hoping i could take out my TP powerline adaptor set in between, why would the P7 not be able to build that powerline connection (as the powerline should be included, AV600). With the setup you've proposed i using 2 P7 nodes (which according to specs, includes a AV600) and 1 TL-WPA4220 KIT (which only is AV500).. 

The AV500 kit works perfectly, but the P7 seems to be relying on being connected to the other P7's wife connection vs powerline. 

I want to disable (or not use) the abilty to connect to the other deco's on wife but just use the powerline.

Hope that makes sense,

Leon

@TP-Link_Deco,

I am getting 14 ms ping response and a 40Mbps download / 4Mbps upload (Not bad for a 50Mbps /5Mbps internet subscription).. So the connection speed seems good enough and i must say the setup (P7 ------ TL-PA4010 )---- powerline------(TPWPA-4220 -------P7) works really well. I just don't understand why if i have a P7 (AV600 included) i need another powerline set ... I want to disable the P7's trying to use Wifi to connect, but just use the build in powerline feature.. (Which is why i bought them in the first place, it now looks as if i just have a M5)..

thx,

Leon.

I've had a similar problem - and can confirm the behaviour of the Deco P7 is very dodgy when there's a decent powerline link but poor WiFi. 
 

Prior to using the P7 system I had a TP-Link powerline adaptor and separate WiFi access point at the edge of my existing WiFi coverage. This worked perfectly, with a stable 150mpbs+ powerline connection. 
 

I thought I could make my setup more elegant by replacing my router/WiFi APs/powerline adapters with a number of P7 units around my home. 
 

It turns out the P7 unit at the fringe of my WiFi coverage caused nothing but problems. Its borderline / unstable WiFi backhaul causes it to regularly drop out or offer dismal speeds to connected clients - despite having a perfectly robust high-speed powerline link to the main deco, which it could opt to use instead.

The promise of the P7 and wider Deco ecosystem is that it would form a smart mesh, intelligently combining the available backhaul/mesh connections to deliver a robust connection. This is clearly not the case. It should be simple for the P7 to use a reliable powerline link over an unreliable WiFi backhaul - but it simply does not. 
 

I got the P7 units when they just came out, and put the initial problems down to teething issues - hoping TP-link would put out firmware updates to fix these obvious issues. With P7 approaching (approached?) end-of-life, I've now given up hope. 
 

Oh, and per your own documentation a green led on the powerline adapter should mean a link with speeds of 50mbps+. Of course there was a promised software update for over a year which would show actual PL backhaul speeds in the app, but this has not yet materialised. Neither has the ability to manually select a backhaul source which could fix this issue. 
 

I recommended the Deco system to many people, the concept is great and the hardware is great. Unfortunately it seems to be let down by shoddy software (many clear easily reproducible glitches all over the place - reported constantly on this forum: devices losing connectivity, units needing restarting, connected devices in the app not refreshing, overall decay of stability with uptime) and this has not been something tp-link has proven capable of addressing over the years. I'd now hesitate to recommend the system again. Shame - there's such wasted potential here - with the right focus on software tp-link could have the best home mesh network system on the market - by far.

Thanks for your offer to help. I have four P7's in the following topology:

All P7s are plugged directly into a socket and have a solid Green powerline indication. Having previously used a different TP-Link powerline adaptor, I can confirm the wiring supports 150+mbps reliable speeds and roust connectivity.

In general the Lounge Deco has caused a lot of problems. It's clear it doesn't like the fact that it has a weak/unstable wifi connection. Devices connected to it end up with a very unreliable connection - frequently cutting out entirely - despite the fact that it has a stable Powerline backhaul that it could use to reinforce the borderline WiFi link. As a workaround I have now moved this device to a different corner of the lounge, where it has a more stable WiFi link with the Garage Deco - but this is a suboptimal placement for my needs and defeats the point of the P7 supposedly being able to use Powerline to ensure a stable connection even with a weak WiFi backhaul.

In addition to the above, I also encounter:

• When the system has been running for a while, random individual devices often lose their connectivity. Disconnecting and reconnecting them from WiFi doesn't help. The main Deco needs to be rebooted every so often - which resolves the problem for a week or two - but it's obviously frustrating to regularly see devices lose their connectivity and need to kick the system.
• At first, after the main Deco is started, the devices list reliably shows which devices are connected, alongside their up/down speeds. New devices which connect to the network show up in the list and dispatch a push notification. Within a day, the up/down speeds stop showing (merely display '--'), and any new devices connecting to the network don't show up in the list or trigger a notification until the system is restarted. I have exactly the same problem at my workplace (Deco M5s) and at my parents' house (Deco P9 + Deco M5 mix) - so clearly this is a universal issue
