I recently had a power outage do to an animal getting on the power lines. While all my appliances got power, my modem only had the online light on blue solid and no wifi light. I called my ISP thinking it might need to be re provisioned and they couldn't detect the device. I tried resetting it, restarting it, connecting on different ports and nothing.I cant access the gateway via ethernet. I think it might be fried and need a new one if not please let me know what I can do

Try plugging the gateway into a different power outlet, and use an alternate power cord if available.
If the network names still aren’t broadcasting, the next step is to check whether the Ethernet ports are functioning properly.

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.
