SBG7600AC2 Ethernet Ports not working

Question

As the subject says, the Ethernet ports on this device aren’t working.

The WiFi network still works; I’ve done a factory reset and I’ve disabled and re-enabled the ports on it as well. No device I plug into any of the ports works, and the client list doesn’t recognize anything being plugged into it either.

I’ve been fighting with it for the last couple of days, and I really just want this thing replaced.

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:

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

To check the IP address on a Mac:

Click on the Apple menu.
Then, select System Preferences or System Settings.
Navigate to Networks and click on the Ethernet option to view the IP address.
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.
