When setting up the connection between the print server and your LAN, please first set up the "wireless connection" of the print server, and then set up the "wired connection" with your LAN (wired connection to your router or switch). In this way, even when the print server is disconnected from the "wired connection" of your LAN, the "wireless connection can still communicate with your work network (LAN) and can be used normally.

Otherwise, if you first wired the server to your LAN (connect your router or switch), and set up "wired connection", and then set up "wireless connection". When the server is disconnected from the "wired connection" of your LAN, the "wireless connection" between the server and your working network will be unable to communicate and unavailable.

So please first set up the "wireless connection" between the server and your LAN (if you don't need wireless connection, you can directly set up wired connection), and then set up the "wired connection" between the server and your LAN.

When setting "unable to connect", please make sure that the lan1 or lan2 port of the server is not connected to any device“ After wireless connection is set, lan1 and lan2 ports can be connected to any device without affecting the use of wireless connection.

If you accidentally make the wrong setting, please insert into the "RST" hole by the needle (or similar object) , long press for 5 ~ 10 seconds, and release when the "sys" light flashes, the server will return to the factory settings. You can make the correct settings again on the server.

Thank you.
