You can perform a connection test with devices in the network to check whether the machine is properly connected to the network.
The IP address of the machine and the MAC address information are needed to use Remote UI and configure the firewall settings. Check these current settings.
The IP address of the machine and the MAC address information are needed to use Remote UI and configure the firewall settings. Check these current settings.
NOTE
If the IP address is displayed as "0.0.0.0" or "Could not retrieve.", it is not correctly configured. Set the IP address again.
Connecting the machine to a switching hub, for example, may prevent connection to the network even when the IP address is correctly configured. In this case, set a wait time until the machine starts communicating and try connecting again. [Waiting Time for Connection at Startup]
You can check the network settings by printing the network settings list. Printing the Registration Information and Settings
