Wired connection, avoid assigning the IP address manually as:
- IP address: 169.254.xxx. yyy
- Subnet mask: 255.255.0.0.
Such an IP address will cause conflict with the WiFi network of WACS5 (or WACS57) Center and Station, resulting in Center’s disabled Ethernet port. To restore the disabled Ethernet port, restore your WAC5 Center to its factory settings.
