4 ways to fix Comcast status code 221

The Comcast status code 221 means your cable box isn’t connecting to the Internet. You can try a few things to fix this error.

  • First, check for any wider network outages.
  • Examine the cable connection to the box.
  • Reset the box to clear temporary issues.
  • As a last resort, replacing the box may fix the error if other methods do not work.

Here are detailed troubleshooting steps to fix Comcast status code 221 and get your device working again.

1. Check for network outages in your area

Network outages occur when problems impact the internet service for an entire area served by the provider.

During an outage, the network disruption prevents your Comcast cable box from connecting reliably, resulting in error code 221.


  • Contact the Internet Service Provider by phone or website to see if they report any current outages in your local region. Provide your address so you can check your specific location.
  • Check Comcast’s website, online forums, or the provider’s social media for status updates on service problems. Other users may also report outages.
  • If an outage occurs, you will likely need to wait for repairs before the issue can be fixed.

2. Check if the Comcast cable outlet is active

If no network outages are reported, the issue could be with the specific cable connection to your box.

The outlets and cables in your house must work properly for the Comcast box to connect to the internet through the cable line. If any are damaged, status code 221 will occur.


  • Move your cable box to a different outlet location to see if the error disappears. This will help you determine if the issue affects just one outlet.
  • Try connecting another working cable box to the outlet. If the cable still doesn’t work, a technician may need to repair or replace it.
  • Switch to new cables and see if the error code disappears.

3. Reset the cable box

If the network and cable connection seem fine, the issue may lie with the cable box itself.

Resetting this equipment can sometimes address minor glitches or software problems. Clearing out temporary data may allow the box to connect again properly.

Restart from your online account:

If your provider is Comcast Xfinity, you can perform a restart from their online portal using the following steps:                           

  • Access the Comcast Xfinity customer portal and sign into your account.
  • Locate the Support or Troubleshooting section of the site.
  • Select the option to do a System Refresh. This will restart all boxes connected to your account.
  • Alternatively, choose Restart a Single TV Box and pick the box you want to restart.
  • Follow all on-screen instructions until the refresh or restart is fully completed.
  • Check if the issue has been resolved after the restart process is finished.

Use the power button:

If you can’t access the portal, try a power reset with the power button. Follow these steps:

  • Press and hold the button down for 10 full seconds without releasing it. This ensures the box fully powers off.
  • Only let go of the button after 10 seconds.
  • Wait at least 2 minutes before pressing the power button to turn the box back on.
  • The box will take some time to restart and reconnect once powered on fully.

Disconnect the power source:

If the above does not fix the issue, try unplugging the cable box completely from power. Use these steps:

  • Locate where the power cord is connected to the back of the cable box.
  • Gently disconnect the cord from the port on the box by removing it fully.
  • Ensure the power cord’s other end is removed from the wall outlet.
  • Leave the cable box without any power connection for 10 minutes.
  • After 10 minutes, securely reconnect the power cord to the cable box and wall outlet.

4. Visit a local service center or request a replacement

If resetting the Comcast cable box does not solve the status code 221 issue, a hardware problem may prevent a stable connection. In this case, the box itself needs repair or replacement.


  • Contact Comcast Xfinity support to learn the location of the nearest local center for assistance. Then, take the malfunctioning box to the center for examination.
  • Alternatively, visit the nearest Comcast help center and ask your provider to send a replacement box. Provide your account details and describe the troubleshooting methods you have already tried.

The replacement box will connect properly if the issue lies within the original box’s internal components.

If the new box has error code 221, you need a service technician to examine your cable connections.
