have you noticed any Deco would turn flashing red during the disconnection? Just red.

Since only a wireless connection has been mentioned, do you have the same issue on the Ethernet connection from Deco M9 plus? Not tested with Ethernet.

And if standing next to one of the Deco units, will the wireless signal still be weak and stable? Yes. It seems to fluctuate stronger & drop suddenly. My WiFi signal analyzer app confirmed what I saw on the phone's signal bar.

Can you also send me a detailed picture of your network layout, such as how M9 plus is connected to the ISP modem? ISP modem<=> Deco M9+ wifi to devices.

Hi, thank you for the feedback.

May I know who is your internet service provider? and what is the model number of your ISP cable modem?

Could you please also leave me a private message of your TP-Link ID for Deco APP?

By the way, when Deco is red and the internet dropped out, do you need to restart the Deco to restore the internet connection or it could come back online automatically?
