Introduction
If you’re having problems with your XFINITY Home service, it might be due to Internet connection trouble. To fix it, get started with the basic information here.
If you haven’t already checked for reported outages, be sure to do that before trying any fixes yourself.
Power outage
Your system's primary power supply has a battery back up - so you're connected, even in a power outage.
However, if your cable service is out, your high-speed Internet service will be out as well, and this will affect your home system.
System and zone trouble
System and zone trouble appears in the upper right of the subscriber portal and touch screen. It displays when:
- There is a connectivity (cellular, broadband, etc.) or power problem with the touch screen.
- A sensor is inoperable (for example, due to a battery failure).
- A sensor is being tampered with (such as the cover being opened).
What the specific messages mean:
No cell signal
No WiFi signal
No connectivity
Alerts
Power failure
Critical sensor failure
Multiple troubles
Troubleshoot Internet connectivity
Check the power, connections, and installation status
- Make sure the plugs for the devices haven’t come loose, the outlets are working, and a fuse hasn’t blown.
- Check that all the connections are secure.
- Confirm that your account is up to date on payments. Late payments can cause an interruption of service.
- If you were recently installing software, make sure the installation successfully finished.
- If you’ve recently changed or upgraded your firewall and/or antivirus software, disable them. If this resolves the issue, contact the software manufacture.
- If you upgraded to Windows XP, make sure the Windows firewall isn't running. If it is, disable it.
Reset your cable modem
Press the reset button for five seconds. If it doesn't have a reset button, try rebooting it.
Reboot your cable modem
This will temporarily shut down your cable modem in order to restore its functionality.
- Shut down your computer.
- Turn off your modem and unplug it from the power outlet.
- Turn off the wireless router by pressing the power button in the back.
- Plug the modem in and turn it on. Wait two minutes until it’s completely restarted before moving on to Step 5.
- Turn on the wireless router. Wait two minutes until it's completely restarted before moving on to Step 6.
- Turn on the computer.
