Xfinity Modem Steady Orange Light: Meaning & Fix
Quick Conclusion
A steady orange light on an Xfinity modem (e.g., XB6, XB7, XB8) typically indicates a critical provisioning or connectivity failure, often due to a backend DOCSIS issue or a hardware fault. This is not a routine state and requires immediate troubleshooting to restore service, as it signifies the modem cannot establish a proper connection with the ISP network.
Engineer's Pro-Tip
Xfinity XB7 and XB8 gateways have a thermal throttling mechanism; if placed in an enclosed space or near heat sources, they can overheat and display a steady orange light. Keep them at least 6 inches from walls and ensure proper ventilation to prevent this.

At the end of the day, no matter how much people all across the globe like to suggest that you should use proper discernment when targeting groups, when an-easy-to-label group actually pisses them off, it tends to jump straight to "fuck y'all." Unfortunately (and unshockingly) just the way people are.
