Latest firmware.

Background - Bought and installed Deco mid December.  Ring in use for about 1.5 years.

At approx end of January my Ring Doorbell 2 completely died.  Nothing could get it to come back alive, battery was fine, tried a few other batteries. Nothing. 

Ring kindly replaced it, that too died within 2 weeks. 

Replacement came for that, and lasted about 6 hours before it died. 

Each time the death was exactly the same.  Complete and utter brick. 

Ring support had no knowledge of any similar issues or problems with firmware which caused this.  Let alone 3 devices in a row died.

I've looked online and i found reference to 2 other people who had similar issues.  Both had Deco M5's..   the same as me!

Coincidence! 

I spoke to one of them and they told me that they had turned it into AP mode instead of router, turned off Mesh functionality and he hasn't had any problems since. 

Now....I cannot use it in AP mode as the whole reason for purchasing the Deco was because it is a router and provides parental controls etc... none of which would work in AP mode.   Also without Mesh functionality... what is the actual point in having a Mesh system?!

So... my question is.. to anyone.. to TPLink if you actually read these forums...

What about this Mesh system could possibly cause a device to brick?!?  Has anyone heard of it before? 

I have just received and installed my 4th Ring Doorbell and set it up turning Mesh off specifically for it in the Deco settings.  Hopefully I am thinking that this might make the difference?  If it is something else I really don't know what to do, nor to hold accountable. Ring or TPLink?   

Any advice?

thanks in advance
