Model: Deco P9  
Hardware Version: V1
Firmware Version: 1.1.3 Build 20201228 Rel. 55057

Hi.

 

I've a problem with the connection; it was OK previously but for couple of weeks the stability seems very bad with the satellite units

 

I have 3 units of P9 V1.

 

Already upgraded to the latest firmware..

 

Seems the PLC is not working well  ; it keeps disconnected (if view from the status you can sometimes see PLC but sometimes dont)

 

Whats the solution to this?

@Izudeen 

Hi,

 Would the satellite Deco turn red when the connection lost?

Did both of the satellite Deco have the same issue?

If possible, please try to update the following firmware to check:

https://static.tp-link.com/beta/2021/202101/20210118/Deco_P9_1.1.3_20210115_debug.zip

by the way, could you please draw a simple picture of the network topology/ floor map about the location and distance between Deco units;

Thank you very much and wait for your reply.

@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!

I thought of updating here for everyone benefits After using the beta firmware for about a week now ; the mesh works perfectly as it supposed to. Anyone facing the same issue can follow the steps above to resolve this.

@Izudeen 

 

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