Cat6 Ethernet Cable
The solid red light indicates a failure in the logical handshake between the router and the modem. A faulty or degraded Ethernet cable can cause intermittent physical link drops or packet loss that exceeds the firmware's threshold for a 'connected' state. Replacing the cable ensures a clean physical medium for WAN communication.

Deco Power Supply Adapter (12V/2A)
The electromechanical components inside the power adapter can degrade over time, leading to unstable DC output or voltage ripple. This instability can cause the router's System on a Chip (SoC) or Network Interface Controller to crash during high-load periods, resulting in a persistent disconnected state (red light) while the device remains powered.

Main Deco XE75 Unit
If the status light remains solid red after replacing interconnects and power sources, the internal hardware likely has a corrupted firmware block or a failed PHY chip on the logic board. As these units are non-serviceable at the component level (BGA-mounted components), the entire node assembly must be replaced to restore network functionality.
