Welcome to the community.

when it turned red, it will come back to green automatically later, right?

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

Here is some information for your reference:

1. When Deco is red again, please go to Deco APP>More>Advanced>IPv4 and check whether the internet IP address is still here or not.

--If there is no IP address, please try to check with ISP first in case there is any network instability from the service provider side.

--If not, please refer to the private message to install the debug firmware and try to export the logs when Deco turned red again.

Thank you very much.
