Hi, for the LED light when the internet disconnected, is it yellow-red-green, or maybe flashing red?

--Since if the LED became yellow, the Deco might suddenly reboot itself? (Or can you record a video clip about the LED change?)

Did you only have one M4 and have changed M4 with the retailer once before because of the unstable connection?

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

Thank you very much.

Hi， I have sent my email address via private message and please have a check;

How about the model number of the Links 3 cable(or fiber) modem, not the IP address?---normally you will see the model number on the product label;

Just to confirm, you only have one Deco M4, right?

Thank you.

Thank you and please do remember to send me the video;

And How often did this issue occur within one day?

May I know how many devices are connected to Deco M4 and would there be any large traffic internet activities when the internet dropped out;

---in case it is the heavy load that caused the router crashing down;

 Moreover, I would follow up on your case by email, and please have a check of your email box;

Thanks.
