You can set the NWA/WAC to operate in either standalone AP or managed AP mode. When the NWA/
WAC is in standalone AP mode, it can serve as a normal AP, as an RF monitor to search for rouge APs to
help eliminate network threats (if it supports monitor mode and rogue APs detection/containment), or
even as a root AP or a wireless repeater to establish wireless links with other APs in a WDS (Wireless
Distribution System). A WDS is a wireless connection between two or more APs.
Your NWA/WAC’s business-class reliability, SMB features, and centralized wireless management make it
ideally suited for advanced service delivery in mission-critical networks. It uses Multiple BSSID and VLAN
to provide simultaneous independent virtual APs. Additionally, innovations in roaming technology and
QoS features eliminate voice call disruptions.
The NWA/WAC controls network access with Media Access Control (MAC) address filtering, and rogue
Access Point (AP) detection. It also provides a high level of network traffic security, supporting IEEE
802.1x, Wi-Fi Protected Access 2 and Wired Equivalent Privacy (WEP) data encryption.
Your NWA/WAC is easy to install, configure and use. The embedded Web-based configurator enables
simple, straightforward management and maintenance. See the Quick Start Guide for how to make
hardware connections.
1.1.1 Management Mode
The NWA/WAC is a unified AP and can work either in standalone AP mode or in managed AP mode. If
the NWA/WAC and a Zyxel AP controller, such as the NXC2500 or NXC5500, are in the same subnet, it will
be managed by the controller automatically.
An AP controller uses Control And Provisioning of Wireless Access Points (CAPWAP, see RFC 5415) to
discover and configure multiple managed APs.
To set the NWA/WAC to be managed by an AP controller in a different subnet or change between
management modes, use the AC (AP Controller) Discovery screen (see Section 6.4 on page 82).
Table 5 NWA/WAC Management Mode Comparison
MANAGEMENT MODE DEFAULT IP ADDRESS UPLOAD FIRMWARE VIA
Standalone AP
Managed AP Dynamic CAPWAP or FTP
When the NWA/WAC is in standalone AP mode and connects to a DHCP server, it uses the IP address
assigned by the DHCP server. Otherwise, the NWA/WAC uses the default static management IP address
(192.168.1.2). You can use the AC Discovery screen to have the NWA/WAC work as a managed AP.
Dynamic or
Static (192.168.1.2)
Web Configurator or FTP
When the NWA/WAC is in managed AP mode, it acts as a DHCP client and obtains an IP address from
the AP controller. It can be configured ONLY by the AP controller. To change the NWA/WAC back to
standalone AP mode, use the Reset button to restore the default configuration. Alternatively, you need
to check the AP controller for the NWA/WAC’s IP address and use FTP to upload the default
configuration file at conf/system-default.conf to the NWA/WAC and reboot the device.
NWA / WAC Series User’s Guide

1.1.2 MBSSID
A Basic Service Set (BSS) is the set of devices forming a single wireless network (usually an access point
and one or more wireless clients). The Service Set IDentifier (SSID) is the name of a BSS. In Multiple BSS
(MBSSID) mode, the NWA/WAC provides multiple virtual APs, each forming its own BSS and using its own
individual SSID profile.
You can configure multiple SSID profiles, and have all of them 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.
For example, you might want to set up a wireless network in your office where Internet telephony (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 QoS priority, SSID01 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 Land Area Network (LAN) behind the AP and can access
only the Internet.

1.1.3 Dual-Radio
Some of the NWA/WAC models are equipped with dual wireless radios. This means you can configure
two different wireless networks to operate simultaneously.
Note: A different channel should be configured for each WLAN interface to reduce the
effects of radio interference.
You could use the 2.4 GHz band for regular Internet surfing and downloading while using the 5 GHz
band for time sensitive traffic like high-definition video, music, and gaming.
Figure 2 Dual-Radio Application
Chapter 1 Introduction
1.1.4 Root AP
In Root AP mode, the NWA/WAC (Z) can act as the root AP in a wireless network and also allow
repeaters (X and Y) to extend the range of its wireless network at the same time. In the figure below,
both clients A, B and C can access the wired network through the root AP.
NWA / WAC Series User’s Guide
19
Page 20
Figure 3 Root AP Application
Chapter 1 Introduction
On the NWA/WAC in Root AP mode, you can have multiple SSIDs active for regular wireless connections
and one SSID for the connection with a repeater (repeater SSID). Wireless clients can use either SSID to
associate with the NWA/WAC in Root AP mode. A repeater must use the repeater SSID to connect to
the NWA/WAC in Root AP mode.
When the NWA/WAC is in Root AP mode, repeater security between the NWA/WAC and other repeater
is independent of the security between the wireless clients and the AP or repeater. When repeater
security is enabled, both APs and repeaters must use the same pre-shared key. See Section 7.2 on page
85 and Section 12.2 on page 130 for more details.
Unless specified, the term “security settings” refers to the traffic between the wireless clients and the AP.
At the time of writing, repeater security is compatible with the NWA/WAC only.
1.1.5 Repeater
The NWA/WAC can act as a wireless network repeater to extend a root AP’s wireless network range,
and also establish wireless connections with wireless clients.
Using Repeater mode, your NWA/WAC can extend the range of the WLAN. In the figure below, the
NWA/WAC in Repeater mode (Z) has a wireless connection to the NWA/WAC in Root AP mode (X)
which is connected to a wired network and also has a wireless connection to another NWA/WAC in
Repeater mode (Y) at the same time. Z and Y act as repeaters that forward traffic between associated
wireless clients and the wired LAN. Clients A and B access the AP and the wired network behind the AP
through repeaters Z and Y.
NWA / WAC Series User’s Guide
20
Page 21
Figure 4 Repeater Application
Chapter 1 Introduction
When the NWA/WAC is in Repeater mode, repeater security between the NWA/WAC and other
repeater is independent of the security between the wireless clients and the AP or repeater. When
repeater security is enabled, both APs and repeaters must use the same pre-shared key. See Section 7.2
on page 85 and Section 12.2 on page 130 for more details.
Once the security settings of peer sides match one another, the connection between devices is made.
At the time of writing, repeater security is compatible with the NWA/WAC only.
1.2 Ways to Manage the NWA/WAC
You can use the following ways to manage the NWA/WAC.
Web Configurator
The Web Configurator allows easy NWA/WAC setup and management using an Internet browser. This
User’s Guide provides information about the Web Configurator.
Command-Line Interface (CLI)
The CLI allows you to use text-based commands to configure the NWA/WAC. You can access it using
remote management (for example, SSH or Telnet). See the Command Reference Guide for more
information.
File Transfer Protocol (FTP)
This protocol can be used for firmware upgrades and configuration backup and restore.
NWA / WAC Series User’s Guide
21
Page 22
Chapter 1 Introduction
Simple Network Management Protocol (SNMP)
The NWA/WAC can be monitored by an SNMP manager. See the SNMP chapter in this User’s Guide.
1.3 Good Habits for Managing the NWA/WAC
Do the following things regularly to make the NWA/WAC 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 NWA/WAC to its factory default settings. If you backed up an
earlier configuration file, you won’t have to totally re-configure the NWA/WAC; you can simply restore
your last configuration.
1.4 Hardware Connections
See your Quick Start Guide for information on making hardware connections.
1.5 NWA5301-NJ Hardware
1.5.1 110 Punch-Down Block
This section shows you how to use a punch-down tool to seat an 8-wire Ethernet cable to the 110 punchdown block. You can connect a PoE switch to the 110 punch-down block to provide power and
Internet access to the NWA through this connection. An 8-pin Ethernet cable has four pairs of color
coded wires.

1.5.2 Phone Port
Chapter 1 Introduction
Connect a digital telephone to the RJ-45 PHONE port at the bottom of the NWA to forward voice traffic
to/from the telephone switchboard that is connected to the RJ-45 PHONE port on the back of the NWA.
The NWA does not support VoIP (Voice over Internet Protocol) and the PHONE port is NOT for making
calls over the regular networking network (PSTN), either.
1.5.3 Console Port
To use the CLI commands to configure the NWA, connect an RJ-45-to-DB-9 cable to the PHONE port at
the bottom of the NWA.
For local management, you can use a computer with terminal emulation software configured to the
following parameters:
• VT100 terminal emulation

access the NWA/WAC’s web configurator again.
Otherwise, select Static IP when the NWA/WAC is NOT connected to a router or you want to assign it a
fixed IP address. You will need to manually enter:
• the NWA/WAC’s IP address and subnet mask.
• the IP address of the router that helps forward traffic.
• a DNS server's IP address. The Domain Name System (DNS) maps a domain name to an IP address
and vice versa. The DNS server is extremely important because without it, you must know the IP
address of a computer before you can access it.

5.2 What You Need to Know
The following terms and concepts may help as you read through the chapter.
Rogue AP
Rogue APs are wireless access points operating in a network’s coverage area that are not under the
control of the network’s administrators, and can open up holes in a network’s security. See Chapter 11
on page 126 for details.
Friendly AP
Friendly APs are other wireless access points that are detected in your network, as well as any others that
you know are not a threat (those from neighboring networks, for example). See Chapter 11 on page 126
for details.

6.1 Overview
This chapter describes how you can configure the management IP address and VLAN settings of your
NWA/WAC.
The Internet Protocol (IP) address identifies a device on a network. Every networking device (including
computers, servers, routers, printers, etc.) needs an IP address to communicate across the network.
These networking devices are also known as hosts.
Figure 41 IP Setup
CHAPTER 6
Network
The figure above illustrates one possible setup of your NWA/WAC. The gateway IP address is 192.168.1.1
and the managed IP address of the NWA/WAC is 192.168.1.2 (default), but if the NWA/WAC is assigned
an IP address by a DHCP server, the default (192.168.1.2) will not be used. The gateway and the NWA/
WAC must belong in the same IP subnet to be able to communicate with each other.
6.1.1 Management Mode
This discusses using the NWA/WAC in management mode, which determines whether the NWA/WAC is
used in its standalone mode, or as part of a Control And Provisioning of Wireless Access Points (CAPWAP)
network.
About CAPWAP
The NWA/WAC supports CAPWAP. This is Zyxel’s implementation of the CAPWAP protocol (RFC 5415).
The CAPWAP data flow is protected by Datagram Transport Layer Security (DTLS).
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).
NWA / WAC Series User’s Guide
75
Page 76
Chapter 6 Network
Figure 42 CAPWAP Network Example
Note: The NWA/WAC can be a standalone AP (default), or a CAPWAP managed AP.
CAPWAP Discovery and Management
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).
2 The AP sends out a discovery request, looking for a CAPWAP AP controller.
3 If there is an AP controller on the network, it receives the discovery request. If the AP controller is in
Manual mode it adds the details of the AP to its Unmanaged Access Points list, and you decide which
available APs to manage. If the AP controller 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 pre-shared key. The managed AP is ready for association with
wireless clients.
Managed AP Finds the Controller
A managed NWA/WAC can find the controller in one of the following ways:
• Manually specify the controller’s IP address in the Web Configurator’s AC (AP Controller) Discovery
screen.
• Get the controller’s IP address from a DHCP server with the controller’s IP address configured as
option 138.
• Get the controller’s IP address from a DNS server SRV (Service) record.
NWA / WAC Series User’s Guide
76
Page 77
Chapter 6 Network
• Broadcasting to discover the controller within the broadcast domain.
Note: The AP controller needs to have a static IP address. If it is a DHCP client, set the DHCP
server to reserve an IP address for the AP controller.
CAPWAP and IP Subnets
By default, CAPWAP works only between devices with IP addresses in the same subnet.
However, you can configure CAPWAP to operate between devices with IP addresses in different
subnets by doing the following.
• Activate DHCP. Your network’s DHCP server must support option 138 defined in RFC 5415.
• Configure DHCP option 138 with the IP address of the CAPWAP AP controller on your network.
DHCP Option 138 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.
Figure 43 CAPWAP and DHCP Option 138
Notes on CAPWAP
This section lists some additional features of Zyxel’s implementation of the CAPWAP protocol.
• When the AP controller uses its internal Remote Authentication Dial In User Service (RADIUS) server,
managed APs also use the AP controller’s authentication server to authenticate wireless clients.
• 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.
6.1.2 What You Can Do in this Chapter
• The IP Setting screen (Section 6.2 on page 78) configures the NWA/WAC’s LAN IP address.
• The VLAN screen (Section 6.3 on page 79) configures the NWA/WAC’s VLAN settings.
• The AC (AP Controller) Discovery screen (Section 6.3 on page 79) configures the NWA/WAC’s AP
Controller settings.

A Virtual Local Area Network (VLAN) allows a physical network to be partitioned into multiple logical
networks. Devices on a logical network belong to one group. A device can belong to more than one
group. With VLAN, a device cannot directly talk to or hear from devices that are not in the same
group(s); the traffic must first go through a router.
VLAN also increases network performance by limiting broadcasts to a smaller and more manageable
logical broadcast domain. In traditional switched environments, all broadcast packets go to each and
every individual port. With VLAN, all broadcasts are confined to a specific broadcast domain.
IEEE 802.1Q Tag
The IEEE 802.1Q standard defines an explicit VLAN tag in the MAC header to identify the VLAN
membership of a frame across bridges. A VLAN tag includes the 12-bit VLAN ID and 3-bit user priority.
The VLAN ID associates a frame with a specific VLAN and provides the information that devices need to
process the frame across the network.
Use this screen to configure the VLAN settings for your NWA/WAC. To access this screen, click
Configuration > Network > VLAN.
The screen varies depending on whether the NWA/WAC has an extra Ethernet port (except the uplink
port).

6.4 AC (AP Controller) Discovery
This section discusses how to configure the NWA/WAC’s AC (AP Controller) Discovery settings. You can
have the NWA/WAC managed by an AP controller on your network. When you do this, the NWA/WAC
can be configured ONLY by the AP controller. See Section 6.1.1 on page 75 for more information on
management mode and AP Controller.
Note: The AC (AP Controller) Discovery settings are not available in all NWA/WACs. See
Section 1.1 on page 13 for more information.
If you want to return the NWA/WAC to standalone AP mode, you can do one of the two following
options:
• Press the Reset button.
• Check the AP controller for the NWA/WAC’s IP address and use FTP to upload the default
configuration file to the NWA/WAC. You can get the configuration file at conf/system-default.conf.
You must reboot the device after uploading the configuration file.

7.1 Overview
This chapter discusses how to configure the wireless network settings in your NWA/WAC.
The following figure provides an example of a wireless network.
Figure 49 Example of a Wireless Network
CHAPTER 7
Wireless
The wireless network is the part in the blue circle. In this wireless network, devices A and B are called
wireless clients. The wireless clients use the access point (AP) to interact with other devices (such as the
printer) or with the Internet. Your NWA/WAC is the AP.
7.1.1 What You Can Do in this Chapter
• The AP Management screen (Section 7.2 on page 85) manages the NWA/WAC’s general wireless
settings.
• The Rogue AP screen (Section 7.3 on page 88) allows you to assign APs either to the rogue AP list or
the friendly AP list.
• The Load Balancing screen (Section 7.4 on page 91) configures network traffic load balancing
between the APs and the NWA/WAC.
• The DCS screen (Section 7.5 on page 94) configures dynamic radio channel selection.

7.1.2 What You Need to Know
The following terms and concepts may help as you read this chapter.
Station / Wireless Client
A station or wireless client is any wireless-capable device that can connect to an AP using a wireless
signal.
Dynamic Channel Selection (DCS)
Dynamic Channel Selection (DCS) is a feature that allows an AP to 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.
Load Balancing (Wireless)
Wireless load balancing is the process where you limit the number of connections allowed on an wireless
access point (AP) or you limit the amount of wireless traffic transmitted and received on it so the AP
does not become 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 NWA/WAC and is as follows:
• Idle Timeout - Devices that have been idle the longest will be kicked 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 kicked 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 disassociated permanently and never be allowed to
connect.

Chapter 7 Wireless
7.4.1 Disassociating and Delaying Connections
When your AP becomes overloaded, there are two basic responses it can take. The first one is to
“delay” a client connection. This means that the AP withholds the connection until the data transfer
throughput is lowered or the client connection is picked up by another AP. If the client is picked up by
another AP then the original AP cannot resume the connection.
For example, here the AP has a balanced bandwidth allotment of 6 Mbps. If laptop R connects and it
pushes the AP over its allotment, say to 7 Mbps, then the AP delays the red laptop’s connection until it
can afford the bandwidth or the laptop is picked up by a different AP with bandwidth to spare.
Figure 55 Delaying a Connection
The second response your AP can take is to kick the connections that are pushing it over its balanced
bandwidth allotment.
Figure 56 Kicking a Connection
NWA / WAC Series User’s Guide
93
Page 94
Connections are kicked based on either idle timeout or signal strength. The NWA/WAC first looks to see
which devices have been idle the longest, then starts kicking them in order of highest idle time. If no
connections are idle, the next criteria the NWA/WAC analyzes is signal strength. Devices with the
weakest signal strength are kicked first.

7.6 Technical Reference
The following section contains additional technical information about the features described in this
chapter.
Dynamic Channel Selection
When numerous APs broadcast within a given area, they introduce the possibility of heightened radio
interference, especially if some or all of them are broadcasting on the same radio channel. If the
interference becomes too great, then the network administrator must open his AP configuration options
and manually change the channel to one that no other AP is using (or at least a channel that has a
lower level of interference) in order to give the connected stations a minimum degree of interference.
Dynamic channel selection frees the network administrator from this task by letting the AP do it
automatically. The AP can scan the area around it looking for the channel with the least amount of
interference.
In the 2.4 GHz spectrum, each channel from 1 to 13 is broken up into discrete 22 MHz segments that are
spaced 5 MHz apart. Channel 1 is centered on 2.412 GHz while channel 13 is centered on 2.472 GHz.
NWA / WAC Series User’s Guide
94
Page 95
Chapter 7 Wireless
Figure 58 An Example Three-Channel Deployment
Three channels are situated in such a way as to create almost no interference with one another if used
exclusively: 1, 6 and 11. When an AP broadcasts on any of these three channels, it should not interfere
with neighboring APs as long as they are also limited to same trio.
Figure 59 An Example Four-Channel Deployment
However, some regions require the use of other channels and often use a safety scheme with the
following four channels: 1, 4, 7 and 11. While they are situated sufficiently close to both each other and
the three so-called “safe” channels (1,6 and 11) that interference becomes inevitable, the severity of it is
dependent upon other factors: proximity to the affected AP, signal strength, activity, and so on.
Finally, there is an alternative four channel scheme for ETSI, consisting of channels 1, 5, 9, 13. This offers
significantly less overlap that the other one.
Figure 60 An Alternative Four-Channel Deployment
Load Balancing
Because there is a hard upper limit on an AP’s wireless bandwidth, load balancing can be crucial in
areas crowded with wireless users. Rather than let every user connect and subsequently dilute the
NWA / WAC Series User’s Guide
95
Page 96
Chapter 7 Wireless
available bandwidth to the point where each connecting device receives a meager trickle, the load
balanced AP instead limits the incoming connections as a means to maintain bandwidth integrity.
There are three kinds of wireless load balancing available on the NWA/WAC:
Load balancing by station number limits the number of devices allowed to connect to your AP. If you
know exactly how many stations you want to let connect, choose this option.
For example, if your company’s graphic design team has their own AP and they have 10 computers,
you can load balance for 10. Later, if someone from the sales department visits the graphic design
team’s offices for a meeting and he tries to access the network, his computer’s connection is delayed,
giving it the opportunity to connect to a different, neighboring AP. If he still connects to the AP
regardless of the delay, then the AP may boot other people who are already connected in order to
associate with the new connection.
Load balancing by smart classroom also limits the number of devices allowed to connect to your AP.
But any new connections will be just rejected when the AP is overloaded.
Load balancing by traffic level limits the number of connections to the AP based on maximum
bandwidth available. If you are uncertain as to the exact number of wireless connections you will have
then choose this option. By setting a maximum bandwidth cap, you allow any number of devices to
connect as long as their total bandwidth usage does not exceed the configured bandwidth cap
associated with this setting. Once the cap is hit, any new connections are rejected or delayed provided
that there are other APs in range.
Imagine a coffee shop in a crowded business district that offers free wireless connectivity to its
customers. The coffee shop owner can’t possibly know how many connections his AP will have at any
given moment. As such, he decides to put a limit on the bandwidth that is available to his customers but
not on the actual number of connections he allows. This means anyone can connect to his wireless
network as long as the AP has the bandwidth to spare. If too many people connect and the AP hits its
bandwidth cap then all new connections must basically wait for their turn or get shunted to the nearest
identical AP.

8.1 Overview
Use this screen to configure the Bluetooth advertising settings for the NWA/WAC that supports Bluetooth
Low Energy (BLE). Bluetooth Low Energy, which is also known as Bluetooth Smart, transmits less data over
a shorter distance and consumes less power than classic Bluetooth.
8.1.1 What You Need To Know
iBeacon is Apple’s communication protocol on top of Bluetooth Low Energy wireless technology.
Beacons (Bluetooth radio transmitters) or BLE enabled devices broadcast packets to every device
around it to announce their presence. Advertising packets contain their iBeacon ID which mainly
consists of the UUID, major number, minor number and TX (transmit) power. The ID is used to distinguish
beacons in your network.
CHAPTER 8
Bluetooth
The universally unique identifier (UUID) is a 128-bit (16-byte) number which can be used to identify a
service, a device, a manufacturer or an owner. The 2-byte major number is to identify and distinguish a
group, and the 2-byte minor number is to identify and distinguish an individual.
For example, you can set all the beacons in one network to share the same UUID, the beacons in a
particular room to use the same major number, and each beacon in the room can have its own minor
number.
NETWORK A
ROOM X ROOM Y
BEACON 1 BEACON 2 BEACON 3
