My SB6183 modem is working and the ISP confirms I have connection from their side but I am getting no indication via lights that the Ethernet connection is working.  How can I confirm if the Ethernet port is damaged or not?

Please try changing the Ethernet cable, and consider swapping the ends to see if that helps.

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.
