CHAPTER 1

Introducing the ZyXEL Device

This chapter introduces the main applications and features of the ZyXEL Device. It also introduces the ways you can manage the ZyXEL Device.

1.1 Introducing the ZyXEL Device

Your ZyXEL Device extends the range of your existing wired network without additional wiring, providing easy network access to mobile users.
It is highly versatile, supporting multiple BSSIDs simultaneously (eight in the NWA-3160 and NWA-3163, four in the NWA-3165). The Quality of Service (QoS) features allow you to prioritize time-sensitive or highly important applications such as VoIP.
Multiple security profiles allow you to easily assign different types of security to groups of users. The ZyXEL Device controls network access with MAC address filtering, rogue AP detection (NWA-3160 and NWA-3163 only), layer 2 isolation and an internal authentication server. It also provides a high level of network traffic security, supporting IEEE 802.1x, Wi-Fi Protected Access (WPA), WPA2 and WEP data encryption.
Your ZyXEL Device is easy to install, configure and use. The embedded Web-based configurator enables simple, straightforward management and maintenance.
See the Quick Start Guide for instructions on how to make hardware connections.
At the time of writing, this User’s Guide covers the following models.

The ZyXEL Device can be configured to use the following WLAN operating modes
1 AP 2 Bridge/Repeater (NWA-3160 and NWA-3163 only) 3 AP+Bridge (NWA-3160 and NWA-3163 only) 4 MBSSID
Applications for each operating mode are shown below.
ZyXEL NWA-3160 Series User’s Guide

Chapter 1 Introducing the ZyXEL Device
" A different channel should be configured for each WLAN interface to reduce the
effects of radio interference.
1.2.1 Access Point
The ZyXEL Device is an ideal access solution for wireless Internet connection. A typical Internet access application for your ZyXEL Device is shown as follows. Stations A, B and C can access the wired network through the ZyXEL Devices.
Figure 1 Access Point Application
1.2.2 Bridge / Repeater (NWA-3160 and NWA-3163 Only)
The ZyXEL Device can act as a wireless network bridge and establish wireless links with other APs. In the figure below, the two ZyXEL Devices (A and B) are connected to independent wired networks and have a bridge connection (A can communicate with B) at the same time. A ZyXEL Device in repeater mode (C) has no Ethernet connection. When the ZyXEL Device is in bridge mode, you should enable STP to prevent bridge loops.
When the ZyXEL Device is in Bridge / Repeater mode, security between APs (the Wireless Distribution System or WDS) is independent of the security between the wireless stations and the AP. If you do not enable WDS security, traffic between APs is not encrypted. When WDS security is enabled, both APs must use the same pre-shared key. See Section 8.7.3 on page 116 for more details.
Once the security settings of peer sides match one another, the connection between devices is made.
At the time of writing, WDS security is compatible with other ZyXEL access points only. Refer to your other access point’s documentation for details.

Page 34
Chapter 1 Introducing the ZyXEL Device
In the figure below, A and B use X as an AP to access the wired network, while X and Y communicate in bridge mode.
When the ZyXEL Device is in AP + Bridge mode, security between APs (the Wireless Distribution System or WDS) is independent of the security between the wireless stations and the AP. If you do not enable WDS security, traffic between APs is not encrypted. When WDS security is enabled, both APs must use the same pre-shared key. See Section 8.7.4 on page 120 for more details.
Unless specified, the term “security settings” refers to the traffic between the wireless stations and the ZyXEL Device.
Figure 4 AP+Bridge Application
1.2.4 MBSSID
A BSS (Basic Service Set) is the set of devices forming a single wireless network (usually an access point and one or more wireless clients). An SSID (Service Set IDentifier) is the name of a BSS. In MBSSID (Multiple BSS) mode, the ZyXEL Device provides multiple virtual APs, each forming its own BSS and using its own individual SSID profile.
You can configure up to sixteen SSID profiles, and have up to eight active at any one time.
You can assign different wireless and security settings to each SSID profile. This allows you to compartmentalize groups of users, set varying access privileges, and prioritize network traffic to and from certain BSSs.
To the wireless clients in the network, each SSID appears to be a different access point. As in any wireless network, clients can associate only with the SSIDs for which they have the correct security settings.

Chapter 1 Introducing the ZyXEL Device
For example, you might want to set up a wireless network in your office where Internet telephony (Voice over IP, or VoIP) users have priority. You also want a regular wireless network for standard users, as well as a ‘guest’ wireless network for visitors. In the following figure, VoIP_SSID users have Quality of Service (QoS) priority, SSID03 is the wireless network for standard users, and Guest_SSID is the wireless network for guest users. In this example, the guest user is forbidden access to the wired LAN behind the AP and can access only the Internet.
Figure 5 Multiple BSSs
1.2.5 Pre-Configured SSID Profiles
The ZyXEL Device has two pre-configured SSID profiles.
1 VoIP_SSID. This profile is intended for use by wireless clients requiring the highest
QoS (Quality of Service) level for VoIP (Voice over IP) telephony and other applications requiring low latency. The QoS level of this profile is not user-configurable. See Chapter
8 on page 103 for more information on QoS.
2 Guest_SSID. This profile is intended for use by visitors and others who require access
to certain resources on the network (an Internet gateway or a network printer, for example) but must not have access to the rest of the network. Layer 2 isolation is enabled (see Section 11.1 on page 145), and QoS is set to NONE. Intra-BSS traffic blocking is also enabled (see Section 8.1.1 on page 103). These fields are all user-configurable.

1.3 CAPWAP (NWA-3160 and NWA-3163 Only)

CAPWAP allows a single access point (the AP controller) to manage up to eight other access points (the managed APs). The managed APs receive all their configuration information from the AP controller. This includes radio configuration (such as the wireless channel to use, permitted data rates, and so on), security profile and SSID profile information. The managed APs’ web configurators are disabled, and they are managed entirely by the AP controller.
At the time of writing, the NWA-3160 is the only ZyXEL AP model that can be a CAPWAP controller.
At the time of writing, the following ZyXEL AP models can be CAPWAP managed APs:
•NWA-3160
•NWA-3163
•NWA-3500
•NWA-3550

1.4 Ways to Manage the ZyXEL Device

Use any of the following methods to manage the ZyXEL Device.
• Web Configurator. This is recommended for everyday management of the ZyXEL Device using a (supported) web browser.
• Command Line Interface. Line commands are mostly used for troubleshooting by service engineers.
• SMT (NWA-3165 only). System Management Terminal is a text-based configuration menu that you can use to configure your device. Use Telnet to access the SMT.
• FTP for firmware upgrades and configuration backup and restore.
• SNMP. The device can be monitored by an SNMP manager. See the SNMP chapter in this User’s Guide.

1.5 Good Habits for Managing the ZyXEL Device

Do the following things regularly to make the ZyXEL Device more secure and to manage it more effectively.
• Change the password often. Use a password that’s not easy to guess and that consists of different types of characters, such as numbers and letters.
• Write down the password and put it in a safe place.
• Back up the configuration (and make sure you know how to restore it). Restoring an earlier working configuration may be useful if the device becomes unstable or even crashes. If you forget your password, you will have to reset the ZyXEL Device to its factory default settings. If you backed up an earlier configuration file, you won’t have to totally re-configure the ZyXEL Device; you can simply restore your last configuration.

CHAPTER 3

Tutorial

This chapter first provides an overview of how to configure the wireless LAN on your ZyXEL Device, and then gives step-by-step guidelines showing how to configure your ZyXEL Device for some example scenarios.

3.1 How to Configure the Wireless LAN

This section shows how to choose which wireless operating mode you should use on the ZyXEL Device, and the steps you should take to set up the wireless LAN in each wireless mode. See Section 3.1.3 on page 48 for links to more information on each step.
" This section describes how to use the ZyXEL Device in standalone mode. For
information on using the ZyXEL Device in a CAPWAP network, see Chapter 5 on
page 77 and Chapter 6 on page 81.
3.1.1 Choosing the Wireless Mode
•Use Access Point operating mode if you want to allow wireless clients to access your wired network, all using the same security and Quality of Service (QoS) settings. See
Section 1.2.1 on page 32 for details.
•Use Bridge/Repeater operating mode (NWA-3160 and NWA-3163 only) if you want to use the ZyXEL Device to communicate with other access points. See Section 1.2.2 on
page 32 for details.
The ZyXEL Device is a bridge when other APs access your wired Ethernet network through the ZyXEL Device.
The ZyXEL Device is a repeater when it has no Ethernet connection and allows other APs to communicate with one another through the ZyXEL Device.
•Use AP+Bridge operating mode (NWA-3160 and NWA-3163 only) if you want to use the ZyXEL Device as an access point (see above) while also communicating with other access points. See Section 1.2.3 on page 33 for details.
•Use MBSSID operating mode if you want to use the ZyXEL Device as an access point with some groups of users having different security or QoS settings from other groups of users. See Section 1.2.4 on page 34 for details.

3.2 How to Configure Multiple Wireless Networks

In this example, you have been using your ZyXEL Device as an access point for your office network (See your Quick Start Guide for information on how to set up your ZyXEL Device in Access Point mode). Now your network is expanding and you want to make use of the MBSSID feature (see Section 10.1 on page 137) to provide multiple wireless networks. Each wireless network will cater for a different type of user.
You want to make three wireless networks: one standard office wireless network with all the same settings you already have, another wireless network with high Quality of Service (QoS) settings for Voice over IP users, and a guest network that allows visitors to your office to access only the Internet and the network printer.
To do this, you will take the following steps:
1 Change the operating mode from Access Point to MBSSID and reactivate the standard
network.
2 Configure a wireless network for Voice over IP users. 3 Configure a wireless network for guests to your office.
The following figure shows the multiple networks you want to set up. Your ZyXEL Device is marked Z, the main network router is marked A, and your network printer is marked B.
48
ZyXEL NWA-3160 Series User’s Guide
Page 49
Figure 13 Tutorial: Example MBSSID Setup
Chapter 3 Tutorial
The standard network (SSID04) has access to all resources. The VoIP network (VoIP_SSID) has access to all resources and a high Quality of Service (QoS) setting (see Chapter 8 on page
103 for information on QoS). The guest network (Guest_SSID) has access to the Internet and
the network printer only, and a low QoS setting.
To configure these settings, you need to know the MAC (Media Access Control) addresses of the devices you want to allow users of the guest network to access. The following table shows the addresses used in this example.
Table 3 Tutorial: Example Information
Network router (A) MAC address 00:AA:00:AA:00:AA
Network printer (B) MAC address AA:00:AA:00:AA:00
3.2.1 Change the Operating Mode
Log in to the ZyXEL Device (see Section 2.1 on page 41). Click WIRELESS > Wireless. The Wireless screen appears. In this example, the ZyXEL Device is using Access Point operating mode, and is currently set to use the SSID04 profile.

ZyXEL NWA-3160 Series User’s Guide
Page 51
Select the Index box for the entry and click Apply to activate the profile. Your standard wireless network (SSID04) is now accessible to your wireless clients as before. You do not need to configure anything else for your standard network.
3.2.2 Configure the VoIP Network
Next, click WIRELESS > SSID. The following screen displays. Note that the SSID04 SSID profile (the standard network) is using the security01 security profile. You cannot change this security profile without changing the standard network’s parameters, so when you set up security for the VoIP_SSID and Guest_SSID profiles you will need to set different security profiles.

Figure 21 Tutorial: Activate VoIP Profile
Your VoIP wireless network is now ready to use. Any traffic using the VoIP_SSID profile will be given the highest priority across the wireless network.
3.2.3 Configure the Guest Network
When you are setting up the wireless network for guests to your office, your primary concern is to keep your network secure while allowing access to certain resources (such as a network printer, or the Internet). For this reason, the pre-configured Guest_SSID profile has layer-2 isolation and intra-BSS traffic blocking enabled by default. “Layer-2 isolation” means that a client accessing the network via the Guest_SSID profile can access only certain pre-defined devices on the network (see Section 11.1 on page 145), and “intra-BSS traffic blocking” means that the client cannot access other clients on the same wireless network (see Section
8.1.1 on page 103).
Click WIRELESS > SSID. Select Guest_SSID’s entry in the list and click Edit. The following screen appears.
54

• Choose a new SSID for the guest network. In this example, enter Guest_SSID_Example. Note that although the SSID changes, the SSID profile name (Guest_SSID) remains the same as before.
• Select Disable from the Hide Name (SSID) list box. This makes it easier for guests to configure their own computers’ wireless clients to your network’s settings.
• The standard network (SSID04) is already using the security01 profile, and the VoIP network is using the security02 profile (renamed VoIP_Security) so select the security03 profile from the Security field.
• Leave all the other fields at their defaults and click Apply.
3.2.3.1 Set Up Security for the Guest Profile
Now you need to configure the security settings to use on the guest wireless network. Click the Security tab.
You already chose to use the security03 profile for this network, so select security03’s entry in the list and click Edit. The following screen appears.

• Select WPA-PSK in the Security Mode field. WPA-PSK provides strong security that is supported by most wireless clients. Even though your Guest_SSID clients do not have access to sensitive information on the network, you should not leave the network without security. An attacker could still cause damage to the network or intercept unsecured communications.
• Enter the PSK you want to use in your network in the Pre Shared Key field. In this example, the PSK is “ThisismyGuestWPApre-sharedkey”.
• Click Apply. The WIRELESS > Security screen displays. Ensure that the Profile Name for entry 3 displays “Guest_Security” and that the Security Mode is WPA-PSK.

3.2.4 Testing the Wireless Networks
To make sure that the three networks are correctly configured, do the following.
• On a computer with a wireless client, scan for access points. You should see the Guest_SSID network, but not the VoIP_SSID network. If you can see the VoIP_SSID network, go to its SSID Edit screen and make sure Hide Name (SSID) is set to Enable.
Whether or not you see the standard network’s SSID (SSID04) depends on whether “hide SSID” is enabled.

Chapter 3 Tutorial
• Try to access each network using the correct security settings, and then using incorrect security settings, such as the WPA-PSK for another active network. If the behavior is different from expected (for example, if you can access the VoIP wireless network using the security settings for the Guest_SSID wireless network) check that the SSID profile is set to use the correct security profile, and that the settings of the security profile are correct.
• Access the Guest_SSID network and try to access other resources than those specified in the Layer 2 Isolation (l2isolation01) profile screen.
You can use the ping utility to do this. Click Start > Run... and enter “cmd” in the Open: field. Click OK. At the c:\> prompt, enter “ping 192.168.1.10” (substitute the IP address of a real device on your network that is not on the layer 2 isolation list). If you receive a reply, check the settings in the WIRELESS > Layer-2 Isolation > Edit screen, and ensure that the correct layer 2 isolation profile is enabled in the Guest_SSID profile screen.

3.3 How to Set Up and Use Rogue AP Detection

This example shows you how to configure the rogue AP detection feature on the ZyXEL Device.
" This feature is available on the NWA-3160 and NWA-3163 only.
A rogue AP is a wireless access point operating in a network’s coverage area that is not a sanctioned part of that network. The example also shows how to set the ZyXEL Device to send out e-mail alerts whenever it detects a rogue wireless access point. See Chapter 13 on page 157 for background information on the rogue AP function and security considerations.
In this example, you want to ensure that your company’s data is not accessible to an attacker gaining entry to your wireless network through a rogue AP.
Your wireless network operates in an office building. It consists of four access points (all ZyXEL Devices) and a variable number of wireless clients. You also know that the coffee shop on the ground floor has a wireless network consisting of a single access point, which can be detected and accessed from your floor of the building. There are no other static wireless networks in your coverage area.
The following diagram shows the wireless networks in your area. Your access points are marked A, B, C and D. You also have a network mail/file server, marked E, and a computer, marked F, connected to the wired network. The coffee shop’s access point is marked 1.

Figure 28 Tutorial: Wireless Network Example
Chapter 3 Tutorial
In the figure, the solid circle represents the range of your wireless network, and the dashed circle represents the extent of the coffee shop’s wireless network. Note that the two networks overlap. This means that one or more of your APs can detect the AP (1) in the other wireless network.
When configuring the rogue AP feature on your ZyXEL Devices in this example, you will need to use the information in the following table. You need the IP addresses of your APs to access their Web configurators, and you need the MAC address of each AP to configure the friendly AP list. You need the IP address of the mail server to set up e-mail alerts.
Table 4 Tutorial: Rogue AP Example Information

Chapter 3 Tutorial
" The ZyXEL Device can detect the MAC addresses of APs automatically.
However, it is more secure to obtain the correct MAC addresses from another source and add them to the friendly AP list manually. For example, an attacker’s AP mimicking the correct SSID could be placed on the friendly AP list by accident, if selected from the list of auto-detected APs. In this example you have spoken to the coffee shop’s owner, who has told you the correct MAC address of his AP.
In this example, you will do the following things.
1 Set up and save a friendly AP list. 2 Activate periodic Rogue AP Detection. 3 Set up e-mail alerts. 4 Configure your other access points. 5 Test the setup.
3.3.1 Set Up and Save a Friendly AP list
Take the following steps to set up and save a list of access points you want to allow in your network’s coverage area.
1 On a computer connected to the wired network (F in the previous figure), open your
Internet browser and enter the URL of access point A (192.168.1.1). Login to the Web configurator and click ROGUE AP > Friendly AP. The following screen displays.
Figure 29 Tutorial: Friendly AP (Before Data Entry)

Chapter 3 Tutorial
•In the Send Immediate Alert section, select the events you want to trigger immediate e­mails. Ensure that Rogue AP is selected.
• Click Apply.
3.3.4 Configure Your Other Access Points
Access point A is now configured to do the following.
• Scan for access points in its coverage area every ten minutes.
• Recognize friendly access points from a list.
• Send immediate alerts to your email account if it detects an access point not on the list.
Now you need to configure the other wireless access points on your network to do the same things.
For each access point, take the following steps.
1 From a computer on the wired network, enter the access point’s IP address and login to
its Web configurator. See Table 4 on page 59 for the example IP addresses.
2 Import the friendly AP list. Click ROGUE AP > Configuration > Browse.... Find the
“Flist” file where you previously saved it on the network and click Open.
3 Click Import. Check the ROGUE AP > Friendly AP screen to ensure that the friendly
AP list has been correctly uploaded.
4 Activate periodic rogue AP detection. See Section 3.3.2 on page 62. 5 Set up e-mail logs as in Section 3.3.3 on page 63, but change the Mail Subject field so
you can tell which AP the alerts come from (“ALERT_Access_Point_B”, etc.)
3.3.5 Test the Setup
Next, test your setup to ensure it is correctly configured.
• Log into each AP’s Web configurator and click ROGUE AP > Rogue AP. Click Refresh. If any of the MAC addresses from Table 5 on page 60 appear in the list, the friendly AP function may be incorrectly configured - check the ROGUE AP > Friendly AP screen.
If any entries appear in the rogue AP list that are not in Table 5 on page 60, write down the AP’s MAC address for future reference and check your e-mail inbox. If you have received a rogue AP alert, email alerts are correctly configured on that ZyXEL Device.
• If you have another access point that is not used in your network, make a note of its MAC address and set it up next to each of your ZyXEL Devices in turn while the network is running.
Either wait for at least ten minutes (to ensure the ZyXEL Device performs a scan in that time) or login to the ZyXEL Device’s Web configurator and click ROGUE AP > Rogue AP > Refresh to have the ZyXEL Device perform a scan immediately.
• Check the ROGUE AP > Rogue AP screen. You should see an entry in the list with the same MAC address as your “rogue” AP.
• Check the LOGS > View Logs screen. You should see a Rogue AP Detection entry in red text, including the MAC address of your “rogue” AP.
• Check your e-mail. You should have received at least one e-mail alert (your other ZyXEL Devices may also have sent alerts, depending on their proximity and the output power of your “rogue” AP).

3.4 Using Multiple MAC Filters and L-2 Isolation Profiles

This example shows you how to allow certain users to access only specific parts of your network. You can do this by using multiple MAC filters and layer-2 isolation profiles.
3.4.1 Scenario
In this example, you run a company network in which certain employees must wirelessly access secure file servers containing valuable proprietary data.
You have two secure servers (1 and 2 in the following figure). Wireless user “Alice” (A) needs to access server 1 (but should not access server 2) and wireless user “Bob” (B) needs to access server 2 (but should not access server 1). Your ZyXEL Device is marked Z. C is a workstation on your wired network, D is your main network switch, and E is the security gateway you use to connect to the Internet.
Figure 36 Tutorial: Example Network
3.4.2 Your Requirements
1 You want to set up a wireless network to allow only Alice to access Server 1 and the
Internet.
2 You want to set up a second wireless network to allow only Bob to access Server 2 and
the Internet.
3.4.3 Setup
In this example, you have already set up the ZyXEL Device in MBSSID mode (see Chapter 10
on page 137). It uses two SSID profiles simultaneously. You have configured each SSID
profile as shown in the following table.
Table 6 Tutorial: SSID Profile Security Settings

Intra-BSS traffic blocking
Each SSID profile already uses a different pre-shared key.
In this example, you will configure access limitations for each SSID profile. To do this, you will take the following steps.
1 Configure the SERVER_1 network’s SSID profile to use specific MAC filter and layer-2
2 Configure the SERVER_1 network’s MAC filter profile. 3 Configure the SERVER_1 network’s layer-2 isolation profile. 4 Repeat steps 1 ~ 3 for the SERVER_2 network. 5 Check your settings and test the configuration.
To configure layer-2 isolation, you need to know the MAC addresses of the devices on your network, which are as follows.

USER MAC ADDRESS
Alice 11:22:33:44:55:66
Bob 22:33:44:55:66:77
3.4.4 Configure the SERVER_1 Network
First, you will set up the SERVER_1 network which allows Alice to access secure server 1 via the network switch.
You will configure the MAC filter to restrict access to Alice alone, and then configure layer-2 isolation to allow her to access only the network router, the file server and the Internet security gateway.
Take the following steps to configure the SERVER_1 network.
1 Log into the ZyXEL Device’s Web Configurator and click WIRELESS > SSID. The
following screen displays, showing the SSID profiles you already configured.

Management Mode

This chapter discusses the MGNT MODE (Management Mode) screen (NWA-3160 and NWA-3163 only). This screen determines whether the ZyXEL Device is used in its default, standalone mode, or as part of a CAPWAP (Control And Provisioning of Wireless Access Points) network.

5.1 About CAPWAP

The NWA-3160 and NWA-3163 support CAPWAP (Control And Provisioning of Wireless Access Points). This is ZyXEL’s implementation of the IETF’s (Internet Engineering Task Force) CAPWAP protocol (RFC 4118).
The CAPWAP dataflow is protected by DTLS (Datagram Transport Layer Security).
The following figure illustrates a CAPWAP wireless network. You (U) configure the AP controller (C), which then automatically updates the configurations of the managed APs (M1 ~ M4).
Figure 44 CAPWAP Network Example
U
C
5.1.1 CAPWAP Discovery and Management
M1 M2 M3 M4
DHCP SERVER
The link between CAPWAP-enabled access points proceeds as follows:
1 An AP in managed AP mode joins a wired network (receives a dynamic IP address).
ZyXEL NWA-3160 Series User’s Guide
77
Page 78
Chapter 5 Management Mode
2 The AP sends out a management request, looking for an AP in CAPWAP AP controller
mode.
3 If there is an AP controller on the network, it receives the management request. If the AP
controller is in Manual mode (see Section 6.3.3 on page 89) it adds the details of the AP to its Unmanaged Access Points list (see Section 6.3.1 on page 86), and you decide which available APs to manage. If the AP is in Always Accept mode, it automatically adds the AP to its Managed Access Points list and provides the managed AP with default configuration information, as well as securely transmitting the DTLS (Datagram Transport Layer Security) pre-shared key. The managed AP is ready for association with wireless clients.
5.1.2 CAPWAP and DHCP
CAPWAP managed APs must be DHCP clients, supplied with an IP address by a DHCP server on your network.
Furthermore, the AP controller must have a static IP address; it cannot be a DHCP client.
5.1.3 CAPWAP and IP Subnets
By default, CAPWAP works only between devices with IP addresses in the same subnet (see the appendices for information on IP addresses and subnetting).
However, you can configure CAPWAP to operate between devices with IP addresses in different subnets by doing the following.
• Activate DHCP option 43 on your network’s DHCP server.
• Configure DHCP option 43 with the IP address of the CAPWAP AP controller on your network.
DHCP Option 43 allows the CAPWAP management request (from the AP in managed AP mode) to reach the AP controller in a different subnet, as shown in the following figure.

5.1.4 Notes on CAPWAP
This section lists some additional features of ZyXEL’s implementation of the CAPWAP protocol.
• When the ZyXEL Device is in AP controller mode and uses its internal RADIUS server (see Chapter 15 on page 175), managed APs also use the ZyXEL Device’s authentication server to authenticate wireless clients.
• Only one AP controller can exist in any single broadcast domain.
• If a managed AP’s link to the AP controller is broken, the managed AP continues to use the wireless settings with which it was last provided.

5.2 The Management Mode Screen

Use this screen to configure the ZyXEL Device as a CAPWAP controller (NWA-3160 only) or managed AP, or to use it in its default standalone mode.

management AP. If you do not have an AP controller on your network and want to return the
ZyXEL Device to standalone mode, you must use its physical RESET button. All settings are returned to their default values.
Note: When you set the ZyXEL Device to Managed AP
mode, it becomes a DHCP client. To discover its new IP address, check the DHCP server on your network. If your network has no DHCP server, the ZyXEL Device’s IP address remains the same. You can also check the Controller > AP Lists screen of the AP controller on your network.
Note: If you change the mode in this screen, the ZyXEL
Device restarts. Wait a short while before you attempt to log in again. If you changed the mode to Managed AP, you cannot log in as the web configurator is disabled; you must manage the ZyXEL Device through the management AP on your network.

AP Controller Mode (NWA-3160
Only)
When the ZyXEL Device is an AP controller, it can manage other access points. You configure settings for the AP controller and the managed access points in the AP controller, which then sends the configuration details to the managed APs.
The ZyXEL Device can manage compatible access points only (see Section 1.3 on page 36 for a list of compatible access points). AP controller mode is part of the ZyXEL CAPWAP implementation.
Use the Management Mode screen to set your ZyXEL Device to AP controller mode (see
Section 5.2 on page 79).
