Please help, so tired of the intermittent disconnects 

See this is a pretty common issue on the deco's.

So randomly, and sometimes multiple times a day, the deco would just loose its internet connection,  red light, and would then re-establish connection. 

I have 3 decos connected via ethernet.

Have tested with only the main deco, and still happens.

Tested with a different router, zero disconnects for 3 days - only tested different router for 3 days.

Moment i switch back to Deco, multiple disconnects per day.

Country: South Africa. 

ISP: Coolideas 

Fiber provider:  MetroFiber

Connection:  PPPoE

Mode : Router

Model: Deco M4R

Hw: V2

Firmware:  1.5.8

So all the features is turned off, beam forming, iptv, ddns, fast roaming .. etc

It seems to be better if I manually specify the dns server, and set it to 8.8.8.8 and 8.8.4.4

Which makes me think that the device is accessing a website and if it cant get to it, it tries to reconnect to the internet... seems like a bad strategy 🤔
