Check for an Outage

If there is an outage to services, use your mobile device to check if an outage is taking place. The cause could be that Xfinity is available at all or within your region.

Before reconnecting the power cable to your Xfinity modem or router, let it stand alone for at least 30 seconds to one minute.

If it doesn’t, you’re not fixing the issue with the blinking green light; it could be a problem with your ISP, or the modem could become permanently damaged.

Check Xfinity Account & Billing

The router or modem may not function because you’re not up to date with the invoice cycle. If your ISP turns off your service until payment is made. You can look over this information through your Xfinity account and apply the adjustments.
