Firmware for NAS542

4yawbontva

I want to upgrade the firmware but the NAS tells me the connection to the server is hanging.  You’ve shut down the FTP site and the Download Library doesn’t show my device.  How can I get the latest firmware?  If I try to connect from the NAS the connection hangs and none of the sites here have any useful information.

Hi @4yawbontva

The firmware of the NAS542 can download on the FTP server
ftp://ftp2.zyxel.com/NAS542/firmware/521ABAG9C0.zip
You can use FTP client to download it.
Or you can upgrade on the NAS web GUI, go to Control Panel >System > FW Upgrade >Latest Firmware Check to upgrade it.
