Modem has been working well, today though I cannot connect to the internet. Power icon is green, the second is flashing green, the other 2 are dark. Have rebooted multiple times, no change. Wondering what else I can do.

Could you please let us know the name of your internet service provider and the speed plan you’ve subscribed to?

Based on the LED light status you described, it appears that the modem is not receiving a signal from your internet service provider. This could indicate a service issue or a problem with the physical connection, such as the coaxial cable or signal distribution.

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.
