Get to Know Your Zyxel
1.1 Overview
Your Zyxel Device is a Secure Cloud-managed Router that is controlled using the Zyxel NCC (Nebula
Control Center). NCC is a cloud-based network management system that allows you to remotely
manage and monitor your Zyxel Device. You need to create a myZyxel account to log into the NCC for
management first. You can access the NCC through the NCC web portal using a web browser on your
computer or the Nebula Mobile app on your smartphone.
When your Zyxel Device cannot connect to NCC, see Section on page 17 on using the Local GUI Web
Configurator to configure the Zyxel Device’s WAN settings.
CHAPTER 1

1.1.1 Nebula Management
The Zyxel Device is managed and provisioned by the NCC (Nebula Control Center) when:
• It is connected to NCC.
• It has been registered on NCC.
Table 1 Management Methods
MANAGEMENT METHOD WHEN TO USE IT
Nebula Mobile App Registration, Monitoring and Basic Management
NCC Web Portal Registration, Monitoring and Management
To set up a Zyxel Device, you need to:
1 Connect the Zyxel Device to a broadband modem or router that is connected to the Internet.
2 Install the Zyxel Nebula Mobile app and turn on WiFi on your smartphone to pair with your Zyxel Device.
Make sure your smartphone also has Internet access.
3 Use the Zyxel Nebula Mobile app to set up the Zyxel Device and manage your Zyxel Device.

A WiFi 6E Tri-Band WiFi System emits one 2.4 GHz, one 5 GHz and one 6 GHz WiFi signals. A WiFi 6 Tri-Band
WiFi System emits one 2.4G WiFi signal and two 5G WiFi signals. Dual-Band WiFi Systems emit one 2.4G
signal and one 5G signal.
“Maximum Bandwidth” refers to the sum of the bandwidths of all WiFi signals (2.4G, 5G, and 6G) emitted
by the Zyxel Device.

See the Quick Start Guide for how to do the hardware installation, mounting, and Internet setup.
1.2.1 Tri-Band WiFi
The Zyxel Device is equipped with three WiFi radios. The Zyxel Device uses the WiFi radios to transmit WiFi
signals. This means you can configure three different WiFi networks to operate simultaneously.
The tri-band Zyxel Devices support both 2.4 GHz and 5 GHz, and an additional 5 GHz or 6 GHz WiFi radio
at the same time.
IEEE 802.11a/b/g/n/ac/ax compliant clients can wirelessly connect to the Zyxel Device to access
network resources. You could use the 2.4 GHz band for regular Internet surfing and downloading while
using the 5 GHz or 6 GHz band for time sensitive traffic like high-definition video, music, and gaming.

1.2.2 WiFi 6 / WiFi 6E Introduction
The Zyxel Device supports WiFi 6 and WiFi 6E standards and brings the following features for WiFi 6/WiFi 6E
compatible client devices.
WiFi 6 (IEEE 802.11ax)
WiFi 6 is a WiFi standard that supports both 2.4 GHz and 5 GHz frequency bands and brings the following
major improvements:
Higher Data Transmission Speed
WiFi 6 provides faster transmission data rate than the previous WiFi standards with the following features:
SCR 50AXE Local GUI User’s Guide

Chapter 1 Get to Know Your Zyxel Device
• 1024-QAM (Quadrature Amplitude Modulation) – enhances the data capacity of each transmission
unit.
• 160 MHz Channel Bandwidth – extends the supported channel bandwidth to 160 MHz, providing
higher data throughput.
Enhanced Air Time Utilization
WiFi 6 increases transmission performance in high-density environments that have multiple client devices
with the following features:
• OFDMA (Orthogonal Frequency-Division Multiple Access) – divides channels into sub-channels that
enables multiple transmissions in a single channel.
• BSS Coloring – tags traffic by BSS (Basic Service Set) and identifies traffic from overlapping BSSs. The AP
can ignore traffic of unrelated BSSs and transmit data when a channel is occupied.
• MU-MIMO (Multiple User-Multiple Input Multiple Output) – enables multiple users to connect to the AP
and download/upload traffic simultaneously.
Extended Signal Range
Beamforming – forms the radiating signals into one direction. This enhances the signal strength and
extends the signal transmission range.
Extended Battery Life
TWT (Target Wake Time) – The AP negotiates with client devices so client devices only wakes up and
communicates with the AP in specific periods. This conserves client devices battery life.
WiFi 6E (IEEE 802.11ax – Extended Standard)
WiFi 6E is an extended standard of WiFi 6 (IEEE 802.11ax). WiFi 6E inherits all the WiFi 6 features and brings
with an additional 6 GHz band. The 6 GHz band allows you to avoid possible congested traffic in the
lower 2.4 GHz and 5 GHz bands. WiFi clients must support WiFi 6E to connect to an AP using the 6 GHz
band.
Note: Check your client device’s product specification to see if your client device supports
the 6 GHz band (WiFi 6E). If not, you should still use the 2.4/5 GHz bands for connection.
Note: Not all countries support the 6 GHz band (WiFi 6E).

2.2.1 Wall Mounting
Use the wall mounting method to install your Zyxel Device. See Table 3 on page 11 for more information.
Mark a hole on the wall at least 2 meter-high from the ground level. Drill the hole and insert the included
anchor and wall mount screw into the wall. Align the mounting hole on the Zyxel Device to the wall
mount screw on the wall. Adjust the angle of the Zyxel Device to make sure it is secure in place.

2.3 WPS Button
Use the WPS button to quickly set up a secure WiFi connection between the Zyxel Device and a WPScompatible client device or WiFi extender by adding one device at a time.
To activate WPS:
1 Press the WPS button until the LED blinks green and release it. See Section 2.5 on page 14 for the
Zyxel Device LED table.
2 Press the WPS button on another WPS-enabled client device within range of the Zyxel Device within 120
seconds. The LED blinks green while the Zyxel Device sets up a WPS connection with the other WiFi client
device.
3 Once the connection is successfully made, the LED turns off.
Note: When the Zyxel Device fails to set up a WPS connection, the WPS LED blinks green
for 120 seconds and then turns off.
2.4 Reset Button
If you need to return the Zyxel Device to its default settings, use the RESET button on the rear panel.
