Hi,

My Deco X50-DSL device, which I have been using for a long time without any problems, turned on red after a power outage. After several attempts, I went to the Advanced Settings menu from the mobile application of the device, went to the Quick Settings menu from the window that opened, selected the specific ISP from the window that opened, and entered the PPPoE, username and password, and VLAN value.Then I clicked the Save button and after a few seconds the red light turned into a solid green light and internet access was established.

I hope this method works for those who are experiencing this issue.

Best regards,
