8.3.4 Firmware

The Zyxel Device stores an AP firmware in order to manage supported APs. This screen allows the Zyxel
Device to check for and download new AP firmware when it becomes available on the firmware server.
All APs managed by the Zyxel Device must have the same firmware version as the AP firmware on the
Zyxel Device.
When an AP connects to the Zyxel Device wireless controller, the Zyxel Device will check if the AP has
the same firmware version as the AP firmware on the Zyxel Device. If yes, then the Zyxel Device can
manage it. If no, then the AP must upgrade (or downgrade) its firmware to be the same version as the
AP firmware on the Zyxel Device (and reboot).
The Zyxel Device should always have the latest AP firmware so that:
• APs don't have to downgrade firmware in order to be managed
• All new APs are supported.
Use Check to see if the Zyxel Device has the latest AP firmware. Use Apply to have the Zyxel Device
download the latest AP firmware (see More Details for more information on the firmware) from the
firmware server. If the Zyxel Device does not have enough space for the latest AP firmware, then the
Zyxel Device will delete an existing firmware that no AP is using before downloading the new AP
firmware.
