Xfinity Router Flashing Orange Light: Meaning & Fix
Quick Conclusion
A flashing orange light on an Xfinity router (e.g., XB6, XB7, XB8) typically indicates a boot-up or firmware update process, but can also signal a connectivity issue like a DOCSIS provisioning failure or ISP outage. This is not usually a severe hardware failure but requires troubleshooting to restore service.
Engineer's Pro-Tip
Xfinity XB7 and XB8 gateways have thermal throttling that can cause erratic orange lights; keep them at least 6 inches from walls and in a well-ventilated area to prevent overheating during firmware updates.

Read original threadWhy is this happening?
- A backend DOCSIS provisioning failure from Comcast, often triggered by a recent activation or account change.
- The router is actively downloading or applying a firmware update, which can take several minutes.
- A loose or damaged coaxial cable connection disrupting the signal from the ISP.
- A temporary ISP network outage or maintenance affecting your local node.
Step-by-Step Fix Flow
Perform a Full Power Cycle to clear cache and reset connections
Unplug the power cable from the router, wait 60 seconds to fully discharge capacitors and clear cache, then firmly reconnect the coaxial cable to the yellow port labeled 'Cable' before plugging the power back in. Wait 5-10 minutes for the light to stabilize.
