Could you please let us know if there were any lights on the Ethernet port when the ports were connected?

Please try accessing the web interface by using http://192.168.0.1 on the any device connected via Wi-Fi. 

After logging in, go to Gateway > Hardware > Ethernet. There, you’ll find an option to toggle the port by disabling it and then enabling it again. 

Then, I would suggest you to check if the ethernet connection works. 

If still persists then I would recommend performing a factory reset on the device. This will restore the gateway to its default settings. 

Hi ,

Thanks for the response

Connected with the customer support team and tried these options with no luck.

A replacement request has been placed.
