well, they are TL-PA4010P ones,

I've got a set of 3 and a set of 2,

and of course I've got one adapter connected to the main router (living room) and

three others connected to a desktop computer (office room), a laptop (bedroom) and a satellite receiver (bedroom),

all of them are receivers of course,

they can't be located in the same room of course,

if this was the case, the powerline would be useless..

the fifth one is used as a replacement,

but I haven't seen any imporement no matter what I've tried

I think the light status remains on..

I've also got the latest firmware too

My guess would be that it's the "all time classic" issue of the powerline disconnections,

I couldn't find any other solution, so I followed the only one posted online:

pinging the router from my laptop contiuously, in order to keep the connection alive,

the problem seems to be that the powerline can't keep the connection alive,

even if the power-save feature is turned off of course

hello, 

light status doesn't change, so the powerline should think that it is connected, while it isn't

I can't tell you what happens to the other ones, because I either would work on my desktop or

on my laptop or watch tv (satellite),

however I can tell you that disconnections happen on my laptop only

(even though I even changed the powerline device),

I haven't experienced disconnections on my desktop or on satellite receiver

(however, I spent more time on the laptop than on the other two)

also, I can't move them all to the same room, obviously, due to space issues,

if I could, then powerline adapters would be useless to me

I've also checked with the tpPLC utility,

I'm gettting around 450mbps among the desktop, laptop and the router,

all of them are on different rooms,

it's been a while since I use my satellite receiver, so I guess it shut down itselft

I bought them in Greece:

tp-link av500+ powerline 3-pack Monday, November 14, 2016 and

tp-link powerline tl-pa4010pkit v2 Tuesday, September 19, 2017

and as I said, I've got the latest firmware installed

anyway, as I said pinging the router contiuously fixes the issue,

since I started pinging it, there were no issues,

so, in my opinion, you should stop checking my end and check what in your powerline software

causes it to lose the connection from time to time, 

even though power-saving is turned off!

I don't want it to fall asleep, I want it to keep the connection forever,

no matter if I'm using it or not,

why isn't it possible?

the problem is I can't use the constant router gateway ping from my mobile,

(because my mobile uses the same network too),

and I've had another disconnection today after switching of my laptop,

so, I changed the plug for now,

let's see how it goes there

no buddy, it's not the laptop's fault at all, because I've noticed numerous disconnections on my mobile too

(this powerline provides internet to a wifi access point,

which my mobile connects to and there were disconnections on that too)

anyway, as I've said I plugged it into another socket (and disabled to constant ping of course) and currently monitoring,

for the last couple of days I didn't have a single disconnection
