Hi there @user_ec3a7c, thank you for visiting our Xfinity Community Forums for assistance with your service. I do realize it has been a couple of days we appreciate you using our resources like the Xfinity app or the Status Center to check for interruptions in the area and the status of your device/connection. If you are still having issues feel free to send us a direct message with your full name and service address and we can look further into this.

• Click the "New message" (pencil and paper) icon
• Type "Xfinity Support" in the "To:" line and select "Xfinity Support" from the drop-down list which appears. The "Xfinity Support" graphic replaces the "To:" line
