Hi

1.7.4 was released around January. Did you upgrade to 1.7.4 just two days ago?
It is recommended that you downgrade all Decos (not only main Deco) to 1.7.2 to see if the problem occurs again.
Please help collect the following information:
1. The color of the main Deco light when the problem occurs; the frequency of the problem’
2. How to temporarily restore the connection, through reboot or automatic recovery?
3. Purchase time;
4. Internet service provider and modem model.

Warm regards.
