Hi  @wepeyes ,

It seems your WAN/LAN1 settings is not correct so it can't work properly. Click "Connect" on the page(your screenshot) won't help.

Please go to Settings-->Wired Network-->Internet

Find WAN/LAN1 settings option here. 

The WAN/LAN1 settings depends on your Internet service provider. Default is Dynamic IP.

  Hi @wepeyes,

You may try connect a computer to the Modem directly with EThernet cable, and check if you can receive Internet from it.

If the Internet is working with Ethernet connection to the Modem, please find the IP address of your computer. This IP comes from modem and it can help us detect what we need to do on the router.
