CHAPTER 1
Introduction
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.
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.

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 (Xand 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 (Aand 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.

Chapter 1 Introduction
NWA50AX/NWA90AX/NWA55AXE Series User’s Guide

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. Zand Yact as repeaters that forward traffic between associated
wireless clients and the wired LAN. Clients Aand Baccess the AP and the wired network behind the AP
through repeaters Zand Y.

Figure 4 Repeater Application
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).
1Go to Configuration > Object > WDS Profile in your root AP Web Configurator and click Add.
2Enter a profile name, an SSID for the WDS, and a pre-shared key.
3Do steps 1 and 2 for the wireless repeater using the same SSID and pre-shared key.
4Once 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

Chapter 1 Introduction
NWA50AX/NWA90AX/NWA55AXE Series User’s Guide
16
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.

CHAPTER 2
AP Management
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.
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.
