@TP-Link Thanks for replying

The original issue is that only 1 of the satellite is disconnecting every 5 mins or so ( I have 3 units ) and yes it will turn red and then after a min or so re-established the connection.. and this issue keeps repeating every 5 mins or so.. and the PLC doesn't seem to be stable; sometimes it has; sometimes it doesn't.. this may what cause the unit to keep disconnecting (as the wifi backhaul not sufficient to sustain)

I have updated all the 3 Deco's P9 V1 with the latest beta firmware you have shared. An initial review found that the PLC connection is now much stable; i.e every time I log in to see the PLC status; it is always there; unlike previously as mentioned; most of the time the PLC connection is not there

And my house wiring is a single phase ; hence no issue with PLC backhaul (in theory)

I will monitor another couple days to see whether the issue is truly resolved or not

Please note that I didnt have the issue (same configuration) when initially use this P9 .. cant recall what what the firmware.. but only recently I found this problem.. hopefully this is purely caused by firmware issue and not faulty hardware

One thing I noticed ; with the  problematic P9 unit, the whole network seems sluggish and the admin page become unresponsive when try to login... If i switch it off the loading of the admin page is smooth

@Izudeen I had the same problems as you experienced, running the same hard- and software:

Model: Deco P9

Hardware Version: V1

Firmware Version: 1.1.3 Build 20201228 Rel. 55057

Decided to update all the 3 Deco's P9 V1 with the latest beta firmware as provided this afternoon and seems stable so far. 

I will also monitor for the next few days!

@Izudeen 

Same here! Roaming and stability works fine, seems like the PLC is much more stable with this software version :)

@DanishS  not recommended..it may brick your device. I would suggest you open a new thread and post your configuration and as much detail as possible.. firmware version .. symptoms etc

@Izudeen I applied the firmware mentioned in this thread but I still do not see the PLC connection to my P9 in the garage. I see PLC to the P9 in the basement, but not garage. This DID show PLC at one point to the garage recently, maybe a week or so ago when I last looked, but now I can't get it to show PLC again for the life of me. It gets OK WiFi signal, but I like having the PLC backbone just to ensure my devices in the garage are online. 

@jstump2490  have you ever seen PLC connection to this garage before?
Note if your house is 3 phase wiring you may not see PLC connection at all as it runs on different electrical wiring than your main router.

The issue I had earlier was IT WAS WORKING fine until the auto-update firmware broke my PLC..  it wasn't that I couldn't get PLC working at the said location

Based on ur reply I can assume that you never get PLC working at all in your garage..  its totally different issue than mine

@Izudeen yes, I've seen it working in the garage before. As recent as maybe a couple weeks ago. I have not seen it in the last couple weeks because I don't look all the time, but it has worked. 
 

edit: well, I just looked and it shows PLC now 😑 so maybe I just needed to give it a few minutes after applying the beta firmware for it to show.
