Possible causes

Troubleshooting steps

  1. Check whether the device is configured for DHCP. If so, confirm a DHCP/BOOTP server is available on the connected LAN.
  2. Check for a duplicate IP address. Resolve the conflict before assigning the address again.
  3. If the network does not provide DHCP, configure an appropriate static IP address using WinDiscovery.
  4. After network changes, reboot the device and run discovery again.
