Label
Description
Activate
To turn on an entry, select Activate. To turn off an entry, select it and click Inactivate.
SSID
Enter the SSID name for this profile. This is the name visible on the network to wireless clients. Enter up to 32 characters, spaces and underscores are allowed.
Band Mode
This shows the wireless band which this wireless network uses. 2.4 GHz is the frequency used by IEEE 802.11b/g/n/ax wireless clients. 5 GHz is the frequency used by IEEE 802.11ax/ac/a/n wireless clients.
QoS
Select a Quality of Service (QoS) access category to associate with this SSID. Access categories minimize the delay of data packets across a wireless network. Certain categories, such as video or voice, are given a higher priority due to the time sensitive nature of their data packets.
QoS access categories are as follows:
disable: Turns off QoS for this SSID. All data packets are treated equally and not tagged with access categories.
WMM: Enables automatic tagging of data packets. The Zyxel Device assigns access categories to the SSID by examining data as it passes through it and making a best guess effort. If something looks like video traffic, for instance, it is tagged as such.
WMM_VOICE: All wireless traffic to the SSID is tagged as voice data. This is recommended if an SSID is used for activities like placing and receiving VoIP phone calls.
WMM_VIDEO: All wireless traffic to the SSID is tagged as video data. This is recommended for activities like video conferencing.
WMM_BEST_EFFORT: All wireless traffic to the SSID is tagged as “best effort,” meaning the data travels the best route it can without displacing higher priority traffic. This is good for activities that do not require the best bandwidth throughput, such as surfing the Internet.
WMM_BACKGROUND: All wireless traffic to the SSID is tagged as low priority or “background traffic”, meaning all other access categories take precedence over this one. If traffic from an SSID does not have strict throughput requirements, then this access category is recommended. For example, an SSID that only has network printers connected to it.
Outgoing Interface
Select the outgoing interface that the wireless network uses to transmit packets.
Authentication Settings
 
Security Mode
Select a security mode from the list: open, wep, wpa2, or wpa2-mix.
802.1x
Select this to enable 802.1x secure authentication with a RADIUS server.
Auth. Method
This field is available only when you select the RADIUS Server Type to Internal.
Select an authentication method if you have created any on the Configuration > Object > Auth. Method screen.
Reauthentication Timer
Enter the interval (in seconds) between authentication requests. Enter a 0 for unlimited requests.
PSK
Select this option to use a Pre-Shared Key with WPA encryption.
Pre-Shared Key
Enter a pre-shared key of between 8 and 63 case-sensitive ASCII characters (including spaces and symbols) or 64 hexadecimal characters.
Cipher Type
Select an encryption cipher type from the list.
auto - This automatically chooses the best available cipher based on the cipher in use by the wireless client that is attempting to make a connection.
aes - This is the Advanced Encryption Standard encryption method. It is a more recent development over TKIP and considerably more robust. Not all wireless clients may support this.
Idle Timeout
Enter the idle interval (in seconds) that a client can be idle before authentication is discontinued.
Group Key Update Timer
Enter the interval (in seconds) at which the AP updates the group WPA encryption key.
Pre-Authentication
This field is available only when you set Security Mode to wpa2 or wpa2-mix and enable 802.1x authentication.
Enable or Disable pre-authentication to allow the AP to send authentication information to other APs on the network, allowing connected wireless clients to switch APs without having to re-authenticate their network connection.
Management Frame Protection
This field is available only when you select wpa2 in the Security Mode field and set Cipher Type to aes.
Data frames in 802.11 WLANs can be encrypted and authenticated with WEP, WPA or WPA2. But 802.11 management frames, such as beacon/probe response, association request, association response, de-authentication and disassociation are always unauthenticated and unencrypted. IEEE 802.11w Protected Management Frames allows APs to use the existing security mechanisms (encryption and authentication methods defined in IEEE 802.11i WPA/WPA2) to protect management frames. This helps prevent wireless DoS attacks.
Select the check box to enable management frame protection (MFP) to add security to 802.11 management frames.
Select Optional if you do not require the wireless clients to support MFP. Management frames will be encrypted if the clients support MFP.
Select Required and wireless clients must support MFP in order to join the Zyxel Device’s wireless network.
Hidden SSID
Select this if you want to “hide” your SSID from wireless clients. This tells any wireless clients in the vicinity of the AP using this SSID profile not to display its SSID name as a potential connection. Not all wireless clients respect this flag and display it anyway.
When a SSID is “hidden” and a wireless client cannot see it, the only way you can connect to the SSID is by manually entering the SSID name in your wireless connection setup screen(s) (these vary by client, client connectivity software, and operating system).
Enable Intra-BSS Traffic Blocking
Select this option to prevent crossover traffic from within the same SSID on the Zyxel Device.
Enable U-APSD
Select this option to enable Unscheduled Automatic Power Save Delivery (U-APSD), which is also known as WMM-Power Save. This helps increase battery life for battery-powered wireless clients connected to the Zyxel Device using this SSID profile.
Enable ARP Proxy
The Address Resolution Protocol (ARP) is a protocol for mapping an IP address to a MAC address. An ARP broadcast is sent to all devices on the same Ethernet network to request the MAC address of a target IP address.
Select this option to allow the Zyxel Device to answer ARP requests for an IP address on behalf of a client associated with this SSID. This can reduce broadcast traffic and improve network performance.
802.11k/v Assisted Roaming
Select this option to enable IEEE 802.11k/v assisted roaming on the Zyxel Device. When the connected clients request 802.11k neighbor lists, the Zyxel Device will response with a list of neighbor APs that can be candidates for roaming.
Schedule SSID
Select this option and set whether the SSID is enabled or disabled on each day of the week. You also need to select the hour and minute (in 24-hour format) to specify the time period of each day during which the SSID is enabled/enabled.

Click this to hide or show the Advanced Settings in this window.
2.4GHz General Settings
 
802.11 Band
Select how to let wireless clients connect to the AP.
11b/g: allows either IEEE 802.11b or IEEE 802.11g compliant WLAN devices to associate with the AP. The AP adjusts the transmission rate automatically according to the wireless standard supported by the wireless devices.
11b/g/n: allows IEEE802.11b, IEEE802.11g and IEEE802.11n compliant WLAN devices to associate with the AP. The transmission rate of your AP might be reduced.
Channel Width
Select the wireless channel bandwidth you want the AP to use.
A standard 20 MHz channel offers transfer speeds of up to 144Mbps (2.4GHz) or 217Mbps (5GHZ) whereas a 40MHz channel uses two standard channels and offers speeds of up to 300Mbps (2.4GHz) or 450Mbps (5GHZ).
40 MHz (channel bonding or dual channel) bonds two adjacent radio channels to increase throughput. Because not all devices support all channels, select 20/40MHz to allow the AP to adjust the channel bandwidth automatically.
Select 20MHz if you want to lessen radio interference with other wireless devices in your neighborhood or the wireless clients do not support channel bonding.
*If the environment has poor signal-to-noise (SNR), the Zyxel Device will switch to a lower bandwidth.
Channel Selection
Select the wireless channel which this radio profile should use.
It is recommended that you choose the channel least in use by other APs in the region where this profile will be implemented. This will reduce the amount of interference between wireless clients and the AP to which this profile is assigned.
Select DCS to have the AP automatically select the radio channel upon which it broadcasts by scanning the area around it and determining what channels are currently being used by other devices.
*If you change the country code later, Channel Selection is set to Manual automatically.
Select Manual and specify the channels the AP uses.
Output Power
Enter the maximum output power of the Zyxel Device. If there is a high density of APs in an area, decrease the output power of the Zyxel Device to reduce interference with other APs. Reducing the output power also reduces the Zyxel Device’s effective broadcast radius.
 
Enable DCS Client Aware
This field is available when you set Channel Selection to DCS.
Select this to have the AP wait until all connected clients have disconnected before switching channels.
If you disable this then the AP switches channels immediately regardless of any client connections. In this instance, clients that are connected to the AP when it switches channels are dropped.
2.4 GHz Channel Selection Method
This field is available when you set Channel Selection to DCS.
Select auto to have the AP search for available channels automatically in the 2.4 GHz band. The available channels vary depending on what you select in the 2.4 GHz Channel Deployment field.
Select manual and specify the channels the AP uses in the 2.4 GHz band.
Channel ID
This field is available only when you set Channel Selection to DCS and set 2.4 GHz Channel Selection Method to manual.
Select the check boxes of the channels that you want the AP to use.
2.4 GHz Channel Deployment
This field is available only when you set Channel Selection to DCS and set 2.4 GHz Channel Selection Method to auto.
Select Three-Channel Deployment to limit channel switching to channels 1,6, and 11, the three channels that are sufficiently attenuated to have almost no impact on one another. In other words, this allows you to minimize channel interference by limiting channel-hopping to these three “safe” channels.
Select Four-Channel Deployment to limit channel switching to four channels. Depending on the country domain, if the only allowable channels are 1-11 then the Zyxel Device uses channels 1, 4, 7, 11 in this configuration; otherwise, the Zyxel Device uses channels 1, 5, 9, 13 in this configuration. Four channel deployment expands your pool of possible channels while keeping the channel interference to a minimum.
Time Interval
Select this option to have the Zyxel Device survey the other APs within its broadcast radius at the end of the specified time interval.
DCS Time Interval
This field is available when you set Channel Selection to DCS.
Enter a number of minutes. This regulates how often the AP surveys the other APs within its broadcast radius. If the channel on which it is currently broadcasting suddenly comes into use by another AP, the AP will then dynamically select the next available clean channel or a channel with lower interference.
Schedule
Select this option to have the Zyxel Device survey the other APs within its broadcast radius at a specific time on selected days of the week.
Start Time
Specify the time of the day (in 24-hour format) to have the Zyxel Device use DCS to automatically scan and find a less-used channel.
Week Days
Select each day of the week to have the Zyxel Device use DCS to automatically scan and find a less-used channel.
Advanced Settings
 
Guard Interval
This field is available only when the channel width is 20/40MHz or 20/40/80MHz.
Set the guard interval for this radio profile to either Short or Long.
The guard interval is the gap introduced between data transmission from users in order to reduce interference. Reducing the interval increases data transfer rates but also increases interference. Increasing the interval reduces data transfer rates but also reduces interference.
Enable A-MPDU Aggregation
Select this to enable A-MPDU aggregation.
Message Protocol Data Unit (MPDU) aggregation collects Ethernet frames along with their 802.11n headers and wraps them in a 802.11n MAC header. This method is useful for increasing bandwidth throughput in environments that are prone to high error rates.
A-MPDU Limit
Enter the maximum frame size to be aggregated.
A-MPDU Subframe
Enter the maximum number of frames to be aggregated each time.
Enable A-MSDU Aggregation
Select this to enable A-MSDU aggregation.
Mac Service Data Unit (MSDU) aggregation collects Ethernet frames without any of their 802.11n headers and wraps the header-less payload in a single 802.11n MAC header. This method is useful for increasing bandwidth throughput. It is also more efficient than A-MPDU except in environments that are prone to high error rates.
A-MSDU Limit
Enter the maximum frame size to be aggregated.
RTS/CTS Threshold
Use RTS/CTS to reduce data collisions on the wireless network if you have wireless clients that are associated with the same AP but out of range of one another. When enabled, a wireless client sends an RTS (Request To Send) and then waits for a CTS (Clear To Send) before it transmits. This stops wireless clients from transmitting packets at the same time (and causing data collisions).
A wireless client sends an RTS for all packets larger than the number (of bytes) that you enter here. Set the RTS/CTS equal to or higher than the fragmentation threshold to turn RTS/CTS off.
Beacon Interval
When a wirelessly networked device sends a beacon, it includes with it a beacon interval. This specifies the time period before the device sends the beacon again. The interval tells receiving devices on the network how long they can wait in low-power mode before waking up to handle the beacon. A high value helps save current consumption of the access point.
DTIM
Delivery Traffic Indication Message (DTIM) is the time period after which broadcast and multicast packets are transmitted to mobile clients in the Active Power Management mode. A high DTIM value can cause clients to lose connectivity with the network. This value can be set from 1 to 255.
Enable Signal Threshold
 
Select the check box to use the signal threshold to ensure wireless clients receive good throughput. This allows only wireless clients with a strong signal to connect to the AP.
Clear the check box to not require wireless clients to have a minimum signal strength to connect to the AP.
Station Signal Threshold
Set a minimum client signal strength. A wireless client is allowed to connect to the AP only when its signal strength is stronger than the specified threshold.
-20 dBm is the strongest signal you can require and -76 is the weakest.
Disassociate Station Threshold
Set a minimum kick-off signal strength. When a wireless client’s signal strength is lower than the specified threshold, the Zyxel Device disconnects the wireless client from the AP.
-20 dBm is the strongest signal you can require and -90 is the weakest.
Allow Station Connection after Multiple Retries
Select this option to allow a wireless client to try to associate with the AP again after it is disconnected due to weak signal strength.
Station Retry Count
Set the maximum number of times a wireless client can attempt to re-connect to the AP.
Allow 802.11n/ac stations only
Only select this if you want to deny 802.11b/g/n clients access to the radio.
Multicast Settings
Use this section to set a transmission mode and maximum rate for multicast traffic.
Transmission Mode
Set how the AP handles multicast traffic.
Select Multicast to Unicast to broadcast wireless multicast traffic to all of the wireless clients as unicast traffic. Unicast traffic dynamically changes the data rate based on the application’s bandwidth requirements. The retransmit mechanism of unicast traffic provides more reliable transmission of the multicast traffic, although it also produces duplicate packets.
Select Fixed Multicast Rate to send wireless multicast traffic at a single data rate. You must know the multicast application’s bandwidth requirements and set it in the following field.
Multicast Rate (Mbps)
If you set the multicast transmission mode to fixed multicast rate, set the data rate for multicast traffic here. For example, to deploy 4 Mbps video, select a fixed multicast rate higher than 4 Mbps.
5GHz General Settings
 
802.11 Band
Select how to let wireless clients connect to the AP.
11a: allows only IEEE 802.11a compliant WLAN devices to associate with the Zyxel Device.
11a/n: allows both IEEE802.11n and IEEE802.11a compliant WLAN devices to associate with the Zyxel Device.
11ac: allows IEEE802.11n, IEEE802.11a, and IEEE802.11ac compliant WLAN devices to associate with the Zyxel Device. If the WLAN device isn’t compatible with 802.11ac, the Zyxel Device will communicate with the WLAN device using 802.11n, and so on.

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.

Enter the threshold number of stations at which an AP begins load balancing its connections.
Disassociate station when overloaded
This function is enabled by default and the disassociation priority is always Signal Strength when you set Mode to By Station Number.
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.
Radio 1/2 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

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.
