Select the operating mode for radio 1 or radio 2.
AP Mode means the AP can receive connections from wireless clients and pass their data traffic through to the Zyxel Device to be managed (or subsequently passed on to an upstream gateway for managing).
MON Mode means the AP monitors the broadcast area for other APs, then passes their information on to the Zyxel Device where it can be determined if those APs are friendly or rogue. If an AP is set to this mode it cannot receive connections from wireless clients.
Root AP means the radio acts as an AP and also supports the wireless connections with other APs (in repeater mode) to form a ZyMesh to extend its wireless network.
Repeater AP means the radio can establish a wireless connection with other APs (in either root AP or repeater mode).
*To prevent bridge loops, do NOT set both radios on a managed AP to Repeater AP mode.
*The root AP and repeater AP(s) in a ZyMesh must use the same country code and AP radio profile settings in order to communicate with each other.
*Ensure you restart the managed AP after you change its operating mode.

Load Balancing Setting
 
Enable Load Balancing
Select this to enable load balancing on the Zyxel Device.
Use this section to configure wireless network traffic load balancing between the managed APs in this group.
*Load balancing is not supported on the radio which is working in root AP or repeater AP mode.
Mode
Select a mode by which load balancing is carried out.
Select By Station Number to balance network traffic based on the number of specified stations connected to an AP.
Select By Traffic Level to balance network traffic based on the volume generated by the stations connected to an AP.
Select By Smart Classroom to balance network traffic based on the number of specified stations connected to an AP. The AP ignores association request and authentication request packets from any new station when the maximum number of stations is reached.
If you select By Station Number or By Traffic Level, once the threshold is crossed (either the maximum station numbers or with network traffic), the AP delays association request and authentication request packets from any new station that attempts to make a connection. This allows the station to automatically attempt to connect to another, less burdened AP if one is available.
Max Station Number
Enter the threshold number of stations at which an AP begins load balancing its connections.
Traffic Level
Select the threshold traffic level at which the AP begins load balancing its connections (Low, Medium, High).
The maximum bandwidth allowed for each level is:
Low - 11 Mbps,
Medium - 23 Mbps
High - 35M bps
Disassociate station when overloaded
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 Zyxel Device 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.
*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.

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.

RTLS Overview
Ekahau RTLS (Real Time Location Service) tracks battery-powered Wi-Fi tags attached to APs managed by the Zyxel Device to create maps, alerts, and reports.
The Ekahau RTLS Controller is the centerpiece of the RTLS system. This server software runs on a Windows computer to track and locate Ekahau tags from Wi-Fi signal strength measurements. Use the Zyxel Device with the Ekahau RTLS system to take signal strength measurements at the APs (Integrated Approach / Blink Mode).
Before You Begin
You need:
At least three APs managed by the Zyxel Device (the more APs the better since it increases the amount of information the Ekahau RTLS Controller has for calculating the location of the tags)
IP addresses for the Ekahau Wi-Fi tags
A dedicated RTLS SSID is recommended
Ekahau RTLS Controller in blink mode with TZSP Updater enabled
Security policies to allow RTLS traffic if the Zyxel Device security policy control is enabled or the Ekahau RTLS Controller is behind a firewall.
For example, if the Ekahau RTLS Controller is behind a firewall, open ports 8550, 8553, and 8569 to allow traffic the APs send to reach the Ekahau RTLS Controller.
The following table lists default port numbers and types of packets RTLS uses.
