9.3.4 Firmware

The ZyWALL/USG stores an AP firmware in order to manage supported APs. This screen allows the
ZyWALL/USG to check for and download new AP firmware when it becomes available on the
firmware server. All APs managed by the ZyWALL/USG must have the same firmware version as the
AP fimware on the ZyWALL/USG.
When an AP connects to the ZyWALL/USG wireless controller, the ZyWALL/USG will check if the AP
has the same firmware version as the AP fimware on the ZyWALL/USG. If yes, then the ZyWALL/
USG 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 ZyWALL/USG (and reboot).
The ZyWALL/USG 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 ZyWALL/USG has the latest AP firmware. Use Apply to have the ZyWALL/
USG download the latest AP firmware (see More Details for more information on the firmware)
from the firmware server. If the ZyWALL/USG does not have enough space for the latest AP
firmware, then the ZyWALL/USG will delete an existing firmware that no AP is using before
downloading the new AP firmware.

DESCRIPTION
This function is enabled by default and the disassociation priority is always Signal
Strength when you set Mode to By Smart Classroom.
Select this option to disassociate wireless clients connected to the AP when it becomes
overloaded. If you do not enable this option, then the AP simply delays the connection
until it can afford the bandwidth it requires, or it transfers the connection to another AP
within its broadcast radius.
The disassociation priority is determined automatically by the ZyWALL/USG and is as
follows:
• Idle Timeout - Devices that have been idle the longest will be disassociated first. If
none of the connected devices are idle, then the priority shifts to Signal Strength.
• Signal Strength - Devices with the weakest signal strength will be disassociated
first.
Note: If you enable this function, you should ensure that there are multiple APs within the
broadcast radius that can accept any rejected or kicked wireless clients; otherwise,
a wireless client attempting to connect to an overloaded AP will be kicked
continuously and never be allowed to connect.
