Spectrum Router Blinking Red Light: Meaning & Fix
Quick Conclusion
A blinking red light on a Spectrum router typically indicates a severe connectivity failure, such as a loss of signal from the ISP or a hardware malfunction. This is not a routine status and requires immediate troubleshooting to restore service, as it often points to an external network outage or internal device error.
Engineer's Pro-Tip
Spectrum routers, like the Sagemcom models, have a hidden diagnostic mode: press and hold the reset button for 30 seconds until all lights flash, then release to initiate a factory reset that can clear persistent firmware glitches causing the red blink, but this will erase all custom settings.

Pictures of everything would be nice, but sounds like they fucked up and dipped so they wouldn't have to stay there late
