1.1 Overview

This User’s Guide covers the models listed below:
• NWA50AX
• NWA90AX
• NWA55AXE
The Zyxel Device can be managed in one of the following methods: remote management through Nebula Control Center (NCC) or local management in Standalone Mode. The Zyxel Device runs in standalone mode by default, but it is recommended to use NCC management if it is available for your device. For more information about Access Point (AP) management, see Section 2.1 on page 20.
Use the Zyxel Device to set up a wireless network with other IEEE 802.11a/b/g/n/ac/ax compatible devices in either 2.4 GHz and 5 GHz networks or both at the same time.
CHAPTER 1

Introduction

When two or more APs are interconnected, this network is called a Wireless Distribution System (WDS). See Section 1.2.2 on page 14 for more information on root and repeater APs and how to set them up.
The screens you see in the web configurator may be different depending on the Zyxel Device model you’re using.

1.2 Zyxel Device Roles

This section describes some of the different roles that your Zyxel Device can take up within a network. Not all roles are supported by all models (see Section 1.4 on page 18). The Zyxel Device can serve as a:
Access Point (AP) - This is used to allow wireless clients to connect to the Internet.
Radio Frequency (RF) monitor - An RF monitor searches for rogue APs to help eliminate network
threats if it supports rogue APs detection/containment. An RF monitor cannot simultaneously act as an AP.
Root AP - A root AP connects to the gateway or switch through a wired Ethernet connection and
has wireless repeaters connected to it to extend its range.
Wireless repeater - A wireless repeater wirelessly connects to a root AP and extends the network’s
wireless range.
If a client (D) tries to set up his own AP (R) with weak security settings, the network becomes exposed to threats. The RF monitor (M) scans the area to detect all APs, which can help the network administrator discover these rogue APs.

Chapter 1 Introduction
Figure 1 Zyxel Device Application in a Network
The following figure shows you how to create a secure Wireless Distribution System (WDS). The root AP (Y) is connected to a network with Internet access and has wireless repeaters (X and Z) connected to it to expand the wireless network’s range. Clients (A and B) can access the wired network through the wireless repeaters (X and Z) and/or root AP.
Figure 2 Wireless Distribution System Network Example
The following figure shows an example of a wireless bridge network. The root AP (Y) is connected to a network with Internet access and has a wireless repeater (X) connected to it to expand the wireless network’s range. Clients (A and B) are connected to the wired network through the gateway (G). They can access the wired network through the wireless repeater and/or root AP.
NWA50AX/NWA90AX/NWA55AXE Series User’s Guide

Chapter 1 Introduction
Figure 3 Wireless Bridge Network Example
1.2.1 Root AP
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 Zyxel Device in Root AP mode. A repeater must use the repeater SSID to connect to the Zyxel Device in Root AP mode.
When the Zyxel Device is in Root AP mode, repeater security between the Zyxel Device and other repeaters 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
10.2 on page 77 and Section 13.2 on page 128 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 Zyxel Device only.
1.2.2 Wireless Repeater
Using Repeater mode, your Zyxel Device can extend the range of the WLAN. In the figure below, the Zyxel Device in Repeater mode (Z) has a wireless connection to the Zyxel Device in Root AP mode (X) which is connected to a wired network and also has a wireless connection to another Zyxel Device 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.

Figure 4 Repeater Application
Chapter 1 Introduction
When the Zyxel Device is in Repeater mode, repeater security between the Zyxel Device 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
10.2 on page 77 and Section 13.2 on page 128 for more details.
For NCC managed devices, you only need to enable AP Smart Mesh to automatically create wireless links between APs. See the NCC User’s Guide for more details.
To set up a WDS in standalone mode APs, do the following steps. You should already have the root AP set up (see the Quick Start Guide for hardware connections).
1 Go to Configuration > Object > WDS Profile in your root AP Web Configurator and click Add.
2 Enter a profile name, an SSID for the WDS, and a pre-shared key.
3 Do steps 1 and 2 for the wireless repeater using the same SSID and pre-shared key.
4 Once the security settings of peer sides match one another, the connection between the root and
repeater Zyxel Devices is made.
Note: Frequency bands 5250-5350 MHz and 5470-5725 MHz are not supported in Repeater
mode.
1.2.3 Radio Frequency (RF) Monitor
The Zyxel Device can be set to work as an RF monitor to discover nearby Access Points. The information it obtains from other APs is used to tag possible rogue APs.
The models that do not support MON Mode support Rogue AP Detection (see Section 10.3 on page 82). Rogue AP Detection allows the AP to scan all channels similar to MON Mode except that the Zyxel
NWA50AX/NWA90AX/NWA55AXE Series User’s Guide

Chapter 1 Introduction
Device still works as an AP while it scans the environment for wireless signals. To see which Zyxel Devices support the RF Monitor feature, see Section 1.4 on page 18.

1.3 Sample Feature Applications

This section describes some possible scenarios and topologies that you can set up using your Zyxel Device.
1.3.1 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 Zyxel Device 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 WiFi clients in the network, each SSID appears to be a different access point. As in any WiFi 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 WiFi network in your office where Internet telephony (VoIP) users have priority. You also want a regular WiFi network for standard users, as well as a ‘guest’ WiFi network for visitors. In the following figure, VoIP_SSID users have QoS priority, SSID01 is the WiFi network for standard users, and Guest_SSID is the WiFi network for guest users. In this example, the guest user is forbidden access to the wired Local Area Network (LAN) behind the AP and can access only the Internet.

1.3.2 Dual-Radio
Some of the Zyxel Device 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.

2.1 Management Mode

The Zyxel Device is a unified AP and can be managed by the NCC or work as a standalone device. We recommend you use NCC to manage multiple APs (see the NCC User’s Guide).
Note: Not all models can be managed by NCC or an AC. See Section 1.4 on page 18 to
check whether your product supports these.
The following table shows the default IP addresses and firmware upload methods for different management modes.

CHAPTER 2

AP Management

Built-in Web Configurator
When the Zyxel Device is in standalone mode and connects to a DHCP server, it uses the IP address assigned by the DHCP server. Otherwise, the Zyxel Device uses the default static management IP address (192.168.1.2). You can use the NCC Discovery screen to allow the Zyxel Device to be managed by the NCC.
When the Zyxel Device is managed by the NCC, it acts as a DHCP client and obtains an IP address from the NCC. It can be configured ONLY by the NCC. To change the Zyxel Device back to standalone mode, use the Reset button to restore the default configuration. Alternatively, you need to check the NCC for the Zyxel Device’s IP address and use FTP to upload the default configuration file at conf/ system-default.conf to the Zyxel Device and reboot the device.
2.1.1 Standalone
When working in standalone mode, the Zyxel Device is configured mainly with its built-in Web Configurator. You can only connect to and set up one Zyxel Device at a time in this mode.
See Chapter 5 on page 43 for detailed information about the standalone Web Configurator screens.
2.1.2 Nebula Control Center
In this mode, which is also called cloud mode, you can manage and monitor the Zyxel Device through the Zyxel Nebula cloud-based network management system. This means you can manage devices remotely without the need of connecting to each device directly. It offers many features to better manage and monitor not just the Zyxel Device, but your network as a whole, including supported switches and gateways. Your network can also be managed through your smartphone using the Nebula Mobile app. See Section on page 196 for an example NCC managed network topology.
NWA50AX/NWA90AX/NWA55AXE Series User’s Guide

See the NCC (Nebula Control Center) User’s Guide for how to configure Nebula managed devices. See
Chapter 23 on page 199 if you want to change the Zyxel Device’s VLAN setting or manually set its IP
address.
Note: Make sure your network firewall allows TCP ports 443, 4335, and 6667 as well as UDP port
123 so the device can connect to and sync with the NCC.

2.2 Switching Management Modes

The Zyxel Device is in standalone mode by default, with NCC discovery enabled.
Standalone-to-NCC
Register the Zyxel Device at the NCC website and then turn on the Zyxel Device. Make sure that NCC Discovery is enabled (see Section 9.4 on page 74). The NCC manages the Zyxel Device automatically
when it is discovered.
NCC-to-Standalone
Unregister the Zyxel Device from the NCC organization/site. Reset the Zyxel Device to factory defaults (see Section 25.6 on page 215).

2.3 Zyxel One Network (ZON) Utility

ZON Utility is a program designed to help you deploy and manage a network more efficiently. It detects devices automatically and allows you to do basic settings on devices in the network without having to be near it.
The ZON Utility issues requests via Zyxel Discovery Protocol (ZDP) and in response to the query, the device responds back with basic information including IP address, firmware version, location, system and model name in the same broadcast domain. The information is then displayed in the ZON Utility screen and you can perform tasks like basic configuration of the devices and batch firmware upgrade in it. You can download the ZON Utility at www.zyxel.com and install it on your computer (Windows operating system).

2.4 Ways to Access the Zyxel Device

You can use the following ways to configure the Zyxel Device.
NWA50AX/NWA90AX/NWA55AXE Series User’s Guide
26
Chapter 2 AP Management
Web Configurator
The Web Configurator allows easy Zyxel Device setup and management using an Internet browser. If your Zyxel Device is managed by the NCC or an AC, use this only for troubleshooting if you cannot connect to the Internet. This User’s Guide provides information about the Web Configurator.
NCC
This is the primary means by which you manage the Zyxel Device in cloud (NCC) mode. With the NCC, you can remotely manage and monitor the Zyxel Device through a cloud-based network management system. See the NCC User’s Guide for more information.
ZON Utility
Zyxel One Network (ZON) Utility is a utility tool that assists you to set up and maintain network devices in a simple and efficient way. You can download the ZON Utility at www.zyxel.com and install it on your computer (Windows operating system). For more information on ZON Utility see Section 2.3 on page 22.
Command-Line Interface (CLI)
The CLI allows you to use text-based commands to configure the Zyxel Device. You can access it using remote management (for example, SSH or Telnet) or via the console port. 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.

2.5 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 Zyxel 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 will not have to totally re-configure the Zyxel Device; you can simply restore your last configuration.

9.1 Overview

This chapter describes how you can configure the management IP address and VLAN settings of your Zyxel Device.
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 45 IP Setup
CHAPTER 9

Network

The figure above illustrates one possible setup of your Zyxel Device. The gateway IP address is 192.168.1.1 and the managed IP address of the Zyxel Device is 192.168.1.2 (default), but if the Zyxel Device is assigned an IP address by a DHCP server, the default (192.168.1.2) will not be used. The gateway and the Zyxel Device must belong in the same IP subnet to be able to communicate with each other.
9.1.1 What You Can Do in this Chapter
• The IP Setting screen (Section 9.2 on page 69) configures the Zyxel Device’s LAN IP address.
• The VLAN screen (Section 9.3 on page 71) configures the Zyxel Device’s VLAN settings.
• The NCC Discovery screen (Section 9.4 on page 74) configures the Zyxel Device’s Nebula Control Center (NCC) discovery settings.

Chapter 9 Network
In the figure above, to access and manage the Zyxel Device from computer A, the Zyxel Device and switch B’s ports to which computer A and the Zyxel Device are connected should be in the same VLAN.
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.
Wireless Bridge VLAN ID
Wireless bridge VLAN allows you to have clients in different WiFi networks appear to be in the same virtual network using VLAN IDs. VLAN IDs are sent across the wireless bridge so that only clients with the same VLAN ID receive that network traffic. See Section 1.2 on page 12 for more information on the wireless bridge.
In the figure below, a client (C2) in the branch office wants to connect to the main office (Y). The branch office client (C2) can connect to the main office network using the VLAN ID 10. However, the branch office client (C2) cannot connect to the to the main office network using the VLAN ID 20 because that VLAN ID does not exist in the main office network. To bridge the branch office network and the main office network, the VLAN IDs you set on the Zyxel Device (X) should be the same as the VLAN IDs you set on the root AP (Y).
Figure 48 Wireless Bridge VLAN ID Example
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.

Chapter 10 Wireless
Rogue APs
A rogue AP is a wireless access point operating in a network’s coverage area that is not under the control of the network administrator, and which can potentially open up holes in a network’s security.
In the following example, a corporate network’s security is compromised by a rogue AP (RG) set up by an employee at his workstation in order to allow him to connect his notebook computer wirelessly (A). The company’s legitimate wireless network (the dashed ellipse B) is well-secured, but the rogue AP uses inferior security that is easily broken by an attacker (X) running readily available encryption-cracking software. In this example, the attacker now has access to the company network, including sensitive data stored on the file server (C).
Figure 56 Rogue AP Example
Friendly APs
If you have more than one AP in your wireless network, you should also configure a list of “friendly” APs. Friendly APs are wireless access points that you know are not a threat. It is recommended that you export (save) your list of friendly APs often, especially if you have a network with a large number of access points. Exported lists show MAC addresses in txt file format separated by line breaks.
Rogue AP Detection
This feature allows the Zyxel Device to monitor the WiFi signals for other wireless APs (see also Section
1.2.3 on page 15). Detected APs will appear in the Monitor > Wireless > Detected Device screen, where
the Zyxel Device will label APs with the criteria you select in Suspected Rogue AP Classification Rule as a suspected rogue. The APs which you mark as either rogue or friendly APs in the Monitor > Wireless > Detected Device screen will appear in the Wireless > Rogue AP screen. See Section 1.4 on page 18 to

10.5 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.
NWA50AX/NWA90AX/NWA55AXE Series User’s Guide
86
Chapter 10 Wireless
Figure 60 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 3 channels, it should not interfere with neighboring APs as long as they are also limited to same trio.
Figure 61 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.

12.1 Overview

This chapter shows you how to configure preset profiles for the Zyxel Device.
12.1.1 What You Can Do in this Chapter
• The Radio screen (Section 12.2 on page 96) creates radio configurations that can be used by the APs.
• The SSID screen (Section 12.3 on page 102) configures three different types of profiles for your networked APs.
12.1.2 What You Need To Know
The following terms and concepts may help as you read this chapter.
CHAPTER 12

AP Profile

Wireless Profiles
At the heart of all wireless AP configurations on the Zyxel Device are profiles. A profile represents a group of saved settings that you can use across any number of connected APs. You can set up the following wireless profile types:
Radio - This profile type defines the properties of an AP’s radio transmitter. You can have a maximum of 64 radio profiles on the Zyxel Device.
SSID - This profile type defines the properties of a single wireless network signal broadcast by an AP. Each radio on a single AP can broadcast up to 8 SSIDs. You can have a maximum of 64 SSID profiles on the Zyxel Device.
Security - This profile type defines the security settings used by a single SSID. It controls the encryption method required for a wireless client to associate itself with the SSID. You can have a maximum of 64 security profiles on the Zyxel Device.
MAC Filtering - This profile provides an additional layer of security for an SSID, allowing you to block access or allow access to that SSID based on wireless client MAC addresses. If a client’s MAC address is on the list, then it is either allowed or denied, depending on how you set up the MAC Filter profile. You can have a maximum of 64 MAC filtering profiles on the Zyxel Device.
Layer-2 Isolation - This profile defines the MAC addresses of the devices that you want to allow the associated WiFi clients to have access to when layer-2 isolation is enabled.
SSID
The SSID (Service Set IDentifier) is the name that identifies the Service Set with which a wireless station is associated. Wireless stations associating to the access point (AP) must have the same SSID. In other words, it is the name of the WiFi network that clients use to connect to it.
NWA50AX/NWA90AX/NWA55AXE Series User’s Guide
95
Chapter 12 AP Profile
WEP
WEP (Wired Equivalent Privacy) encryption scrambles all data packets transmitted between the AP and the wireless stations associated with it in order to keep network communications private. Both the wireless stations and the access points must use the same WEP key for data encryption and decryption.
WPA2
WPA2 (IEEE 802.11i) is a WiFi security standard that defines stronger encryption, authentication and key management than WPA. Key differences between WPA2 and WEP are improved data encryption and user authentication.
WPA3
WPA3 is a WiFi security standard based on IEEE 802.11i, with security improvements like adopting enhanced PSK (Pre-Shared Key) authentication mechanism.
Personal vs Enterprise
A secure WiFi connection relies on WiFi encryption and authentication. There are two authentication modes: Personal and Enterprise.
Personal mode requires a password called Pre-Shared Key (PSK). Users enter the same PSK to connect to the WiFi network.
Enterprise mode requires an external RADIUS server for authentication. Authentication of user identity is required to connect to the WiFi network.
IEEE 802.1X
The IEEE 802.1X standard outlines enhanced security methods for both the authentication of wireless stations and encryption key management. Authentication is done using an external RADIUS server.
IEEE 802.11k/v Assisted Roaming
IEEE 802.11k is a standard for radio resource management of wireless LANs, which allows clients to request neighbor lists from the connected AP and discover the best available AP when roaming. An
802.11k neighbor list can contain up to six BSSIDs with the highest RCPI (Received Channel Power
Indicator) value in both bands (5 GHz and 2.4 GHz, in the ratio of 4:2).
The IEEE 802.11v BSS Transition Management feature lets an AP automatically provide load information of the neighbor APs to clients. It helps the Zyxel Device steer clients to a suitable AP for better performance or load balancing.

Method is set 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 channel­hopping 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.
This field is available only when you select 5G in the 802.11 Band field, set Channel Selection to DCS and set 5 GHz Channel Selection Method to auto.
Select this if your APs are operating in an area known to have RADAR devices. This allows the Zyxel Device to downgrade its frequency to below 5 GHz in the event RADAR signal is detected, thus preventing it from interfering with that signal.
Enabling this forces the AP to select a non-DFS channel.
