[NR5101] Why can't I access the Internet with the Ethernet WAN port?

Zyxel_Kay

Background

Some users may experience difficulties accessing the internet through the Ethernet WAN port on the Zyxel NR5101. This issue often arises because the LAN1/WAN port is configured as a LAN port by default.

Solution

1. Check Port Configuration: Ensure the LAN1/WAN port on the NR5101 is set to WAN mode. By default, it's set as a LAN port, which won't allow internet access if connected as a WAN.
2. Enable WAN Port:
   • Navigate to Network Setting > Broadband > Ethernet WAN
   • Switch the port configuration from LAN to WAN.
     
3. Verify Connectivity: After enabling the WAN port, check if the internet connection is established.
