Hello! My S33 modem just up and quit after about a year. When I rebooted it, solid Amber then blinking green for several times then no light. I’ve tried many times but it’s always the same. No xfinity outages in the area. Any ideas?

Please try the following steps to troubleshoot the issue:

  1. Change the power outlet to make sure it’s functioning properly.
  2. Use an alternate power cord to rule out any issues with the original one.
  3. If the issue still persists, try performing a factory reset.

To check the Ethernet port status, you can connect the modem directly to a computer and check the IP address without the coaxial cable connected.

To check the IP address on a Windows computer, please follow these steps:

  1. Press the Windows button + the letter R on your keyboard to open the "Run" command box.
  2. In the box, type "CMD" and press Enter.
  3. A black screen will appear. Type "ipconfig" and press Enter.
  4. Under the category 'Ethernet adapter Ethernet,' you’ll find the IPv4 address.

To check the IP address on a Mac:

  1. Click on the Apple menu.
  2. Then, select System Preferences or System Settings.
  3. Navigate to Networks and click on the Ethernet option to view the IP address.
  4. If you're using an adapter, you’ll see an option for USB under Networks.

If the IP address starts with 169.254.., or if the media state shows 'disconnected' or the category is blank, there could be an issue with the port itself.
