Hi, besides the system log, have you ever noticed whether Deco X20-DSL turns red when the connection is lost?

-if it is, please go to Deco APP>More>Advanced>IPV4 and check whether you could still get a valid IP address here.

Did you need to restart the modem to restore the internet service, or it will come back automatically?

And may I know who is your internet service provider and have you ever checked with ISP whether there would be regular network maintenance on their side which might cause the random connection loss?

Thank you very much.

Hi, in the past 3 days, did the same issue start again? and How often would the disconnection repeat within one day?

-if yes, have you checked about the IPV4 settings when the LED turned red?

By the way, what is your internet connection type, dynamic IP, or PPPoE?

In case later we need to forward your case to the senior engineers, it is suggested that you could send an email to support.forum@tp-link.com with the above information.

Thank you very much.
