Troubleshooting
Browser access must be enabled first. Open Xfinity app → Wi-Fi → View Equipment → Advanced Settings → Admin Tool → toggle ON. Then retry 10.0.0.1.
In Xfinity app go to Gateway Settings → Reset Admin Password to restore the default.
Use IP Passthrough (Firewall → IPv4) instead - preserves xFi parental controls while solving double-NAT.
