Troubleshooting Ethernet Connection Issues with My New Router

Sounds like you might need to check a few settings. Make sure the modem's DHCP server is configured properly. If the modem has DHCP enabled, turn it off on the router's side to avoid conflicts. Plug your laptop into the router and check for what IP address it receives using the command 'ipconfig /all'. If you don't see an IP, you'll need to troubleshoot some more. Windows also has tools to help with Ethernet connection problems, so don't forget to check those out.

What brand and model are you using for both the modem and the router? This can make a difference in troubleshooting since different devices have their own configurations. For example, are you using a Spectrum modem with an Asus router? Knowing the exact models can help in pinpointing issues.

I’d suggest resetting the router to its factory settings. There’s usually a small reset button on the device. Also, have your Spectrum support number handy in case you need to call them for help. The MAC address on the modem is linked to your rental, so your configurations should update automatically, but if not they can push the settings to your new router.

It sounds like your modem should be fine since your laptop works when connected directly. First, double-check that the Ethernet cable is plugged into the WAN port on your router, not a LAN port. I recommend unplugging both your modem and router for about 5 minutes. After that, plug the modem in first, wait for it to fully start up, and then power on the router. Sometimes modems lock onto the MAC address of the first device connected and need a full reset to release it. If you still have issues, you might want to call your ISP for help; it could be a provisioning problem with your new router.

Since it still says the same thing on a brand new router, have you reset the modem? Sometimes that’s overlooked. If it’s working with your laptop, the routing settings of your modem might be blocking communication with the router. You should check if the modem is in bridge mode so that your router can properly receive an IP address.
