@JimJano Did anyone get a real solution to this problem please? I have just started facing this problem on one of my satellite Deco P9's for no reason at all. I tried restarting, rebooting, moved it closer to another satellite that works fine and yet this satellite just drops connection randomly and flashes red and back to steady white and flashing red again going back and forth like this all day.

@JimJano 

I am facing the same problems. After nearly year oif working fine, in an isolated house with no interfering networks units started randomly dropping out and blinking red, even in rooms with a decent WiFi signal from the base unit and, in one case, with an Ethernet link!

 

After trying everything to no avail, in desperation, I deleted the whole network and started from scratch. It seems to be OK except that one of the (four) units refuses to connect, even at 50cm from the base station, connected by Ethernet to the fast ISP fibre optic modem.

 

So, what can I do? I have tried the reset button, still always ends up blinking red.

Been working fine since I bought the P9 kit.  Suddenly last week one node has started randomly dropping and going through a flash red, reboot cycle.  Happening multiple times a day.  Nothing has changed.

 

So frustrating.  Anyone know of a way of getting at the event log/syslog on these devices to see what's occurring.  Work in IT infrstructure, and this is making working from home painful.

Did a bit more playing with the settings in DecoApp. Disabling the IPv6 stack seems to have restored stability. Maybe CPU overload somewhere along the line?

@DarcoMew 

Thank you for the feedback.

According to most of the feedback, the CPU overload will only make the satellite looks like offline, such as disconnected on the Deco APP  but the LED still stays green.

You could monitor the stability for a while.

and if the LED on the satellite units went to red again, it is also suggested that you could try the following firmware if the issue started again:

@TP-Link Thanks for the suggestion.  The stability had got worse over the last few days, and I'm now waiting for a replacement unit to be shipped by amazon, under warranty.  The red LED reboots had started to stop all the DECO units temporarily, although the other 2 recovered within seconds as the faulty unit went through a full reboot sequence.

@JimJano 

 

Thanks for all the info in this chat.  Established that there was probably a hardware fault with one of my nodes.  thanks to Amazon and TP-Link for getting a complete new kit shipped out.  Units replaced, and all working perfectly again.
