Broadband
Broadband Overview
This chapter discusses the Zyxel Device’s Broadband screens. Use these screens to configure your Zyxel Device for Internet access.
A WAN (Wide Area Network) connection is an outside connection to another network or the Internet. It connects your private networks, such as a LAN (Local Area Network) and other networks, so that a computer in one location can communicate with computers in other locations.

What You Need to Know
The following terms and concepts may help as you read this chapter.
WAN IP Address
The WAN IP address is an IP address for the Zyxel Device, which makes it accessible from an outside network. It is used by the Zyxel Device to communicate with other devices in other networks. The ISP dynamically assigns it each time the Zyxel Device tries to access the Internet.
APN
An Access Point Name (APN) is the name of a gateway between a cellular network and another network, such as the Internet. The Zyxel Device requires an APN to connect to a cellular network. Different APNs may provide different services, such as Internet access or MMS (Multi-Media Messaging Service), and different charging methods.
464XLAT
Enable 464XLAT to send IPv4 traffic through the Zyxel Device when the Zyxel Device has an IPv6 WAN address.
464XLAT sends traffic from an IPv4 private network to another IPv4 network across an IPv6-only network. The Zyxel Device acts as a Customer-side Translator (CLAT). The CLAT adds an IPv6 prefix to the outgoing IPv4 packets, encapsulating IPv4 addresses as IPv6 addresses. When the packets go through the IPv6-only network, a Provider-side Translator (PLAT) removes the IPv6 prefixes so as the IPv4 addresses can reach the target IPv4 network.
464XLAT
Before You Begin
You may need to know your Internet access settings such as APN, WAN IP address and SIM card’s PIN code if the INTERNET light on your Zyxel Device is off. Get this information from your service provider.

Cellular Lock Overview
Cellular Lock (PCI Lock) locks the Zyxel Device to the base station that it is currently connected to. This is useful if the Zyxel Device is within range of multiple base stations, and you would prefer the Zyxel Device to connect to one base station over the others.
For Zyxel Devices using 4G LTE connections, identify the base station to lock to by Physical Cell ID.
For Zyxel Devices using 5G NR connections, identify the base station to lock to by Physical Cell ID and the frequency band.
To see the currently connected base station’s Physical Cell ID and RFCN, go to Connection Status > Cellular Info and check the Service Information section.
Cellular Lock (LTE)
Use this screen to configure cellular lock on Zyxel Devices that use 4G LTE connections.
To lock a base station identified by its Physical Cell ID, go to Network Setting > Broadband > Cellular Lock (LTE).
Network Setting > Broadband > Cellular Lock (LTE)
The following table describes the fields in this screen.
LABEL | DESCRIPTION |
|---|---|
LTE(4G) Lock Management | |
PCI Lock | Click the switch button (to the right) to enable PCI (Physical Cell Identifier) Lock on base stations when the Zyxel Device has 4G LTE connections. Physical Cell ID (PCI) is an identifier for a cell, namely a cellular base station. PCI and Radio Frequency Channel Number (RFCN) are combined to specify the base station. |
Add New Rule | Click to add a new cellular lock rule. |
Physical Cell ID | Enter the PCI number (0 – 504) of the base station to which you want the Zyxel Device to connect. |
RFCN | Enter the RFCN (Radio Frequency Channel Number) for the LTE frequency of the specified PCI (1 – 65535). |
Delete | Click the Delete icon to remove an entry. |
Cancel | Click this to return to previous settings without saving. |
Apply | Click this to save and apply your changes. |
Cellular Lock (5G)
Use this screen to configure cellular lock on Zyxel Devices that use 5G NR connections.
To lock a base station identified by its Physical Cell ID and band, go to Network Setting > Broadband > Cellular Lock (5G).
Enabling/Disabling Cellular Lock will make the WAN connection to be temporarily disconnected. 5G (NR) Cellular Lock only works when the Zyxel Device is using the NR5G-SA mode. Make sure the Preferred Access Technology on the Network Setting > Broadband > Cellular Band screen is set to NR5G-SA or NR5G-SA/NR5G-NSA/SG (Auto Switch).Network Setting > Broadband > Cellular Lock (5G)
The following table describes the fields in this screen.
LABEL | DESCRIPTION |
|---|---|
NR(5G) Lock Management | |
PCI_Enable | Click the switch button (to the right) to enable PCI (Physical Cell Identifier) Lock on a base station when the Zyxel Device has a 5G NR connection. |
Band | Enter the band number to which you choose to connect. Make sure to select the same band in the Network Setting > Broadband > Cellular Band screen so as the Zyxel Device can connect to that band. |
PCI | Use this to enter the PCI number of the base station you want the Zyxel Device to connect to (0 – 504). |
RFCN | Enter the RFCN (Radio Frequency Channel Number) for the 5G NR frequency of the specified PCI (1 – 65535). |
SCS | Select the Subcarrier Spacing (SCS) from the drop-down list. Subcarriers are small signal carriers that divide a frequency channel, which is the main carrier wave. Subcarrier spacing is the space between each subcarrier. At the time of writing, SCS ranges from 15-120 KHz.You should select the same SCS that is used by the ISP. |
