Xfinity Router Steady White Light: Meaning & Fix
Quick Conclusion
For Xfinity gateways (e.g., XB6, XB7, XB8), a steady white light indicates the device is fully booted, online, and operating normally with a stable connection to the ISP network. This is a standard operational state, not an error, but if internet service is unavailable, it may point to an upstream network issue or a problem with the connected devices.
Engineer's Pro-Tip
Xfinity XB7 and XB8 gateways have a hidden diagnostic mode: press and hold the WPS button for 10 seconds until the light blinks orange, then release to run a self-test. The light pattern (e.g., steady white after test) indicates hardware health, which can help isolate issues without a technician visit.

Step-by-Step Fix Flow
Check for ISP Network Outage via Xfinity App
Open the Xfinity xFi app or visit xfinity.com/status to verify if there's a reported service outage in your area. If an outage is confirmed, wait for Xfinity to resolve it; no action is needed on the gateway.
