Only connect a regular Ethernet cable to an ETH port. Using any other type of cable or another port (for example, the RS232 port) might severely damage the device.
First solution: Check if the router is able to connect to a different device
Try to connect your phone or laptop to the internet to check if your router is active. If the other device does not connect either, then ask your IT department to resolve your router's connection problem.
Second solution: Replace the Ethernet cable
If the router is connecting properly to a different device, try replacing the Ethernet cable that is connected to the terminal.
Third solution: Check if there is a firewall active on your router
Use dynamic IP addresses on the local network. If not, use a DHCP server to define static IP addresses to ensure unique IP addresses and avoid unexpected issues.
