Advanced settings
WAN (Basic)
Set up the WAN connection mode and modify related parameters under this option. You can
set the connection mode to DHCP, PPPoE or Static IP.
DHCP
Dynamic Host Configuration Protocol (DHCP) is a client or server
protocol that automatically provides you with an Internet Protocol
(IP) host. The IP address and related configuration settings such as
subnet mask and default gateway are all automatically assigned.
PPPoE
Point-to-Point Protocol over Ethernet (PPPoE) is a network protocol
that is mainly used for DSL services whereby individual users connect
to a modem using an Ethernet connection.
Enter the username and password provided by your network service
provider, and click Apply.

13
Static IP
Access the internet using a fixed IP address, subnet mask, gateway
IP address and Primary DNS server. These information should be
provided by your network service provider.
WAN (MAC clone)
When the MAC clone function is enabled, multiple client devices can connect to the CPE and
access the Internet.
Your current MAC address is displayed in this option. Click Reset to set a new MAC address.
Click Clone to copy your host MAC address.
LAN
The default gateway address is 192.168.1.1, and the default subnet mask is 255.255.255.0.
With the DHCP server function enabled, IP addresses will be assigned automatically to client
devices in the network. If the DHCP server function is disabled, the CPE will not assign IP
addresses to the connected client devices. The IP address must be entered on each client
device.
Bridge mode
Bridge mode allows two routers together. When it enabled, it essentially turns the respective
router into a switch. The bridge-enabled router will still transfer data, but it won't perform
traditional Network Access Translation (NAT) processes. Instead, the bridge-enabled router
will extend its port access to the connected devices.
IP passthrough
CPE IP Passthrough hands off the WAN IP to the Ethernet tethering client.
IP lter
By default, any device connected to your CPE network is allowed to access the Internet.
Specify which device cannot access the Internet by adding the device to the blacklist.
MAC lter
By default, any device connected to your CPE network is allowed to access the Internet.
You can specify which device can or cannot access the Internet by adding the device to the
blacklist or whitelist.
Disable All connected devices can access the Internet.
Whitelist Only devices with a MAC address in this list can access the Internet.
Blacklist Devices with a MAC address in this list cannot access the Internet.

14
DDNS
A WAN IP address is needed when some functions of your CPE are enabled. If the WAN IP
address of your CPE changes, these functions may not work properly.
The Dynamic Domain Name Server (DDNS) function allows you to map a dynamic WAN
IP address (public IP address) to a static domain name, helping Internet users (WAN side)
access the CPE network via a static domain name.
DMZ
If external users cannot access certain network services within the LAN, you can enable the
DMZ function and set a new host IP address.
UPnP
Universal Plug and Play (UPnP) is a set of networking protocols that allows connected
devices to discover each other and establish functional network services for data sharing,
communications, and entertainment.
VPN
Virtual Private Network (VPN) is a dedicated network across the shared or public network
(usually the Internet). The VPN technology allows employees at a branch of an enterprise
and employees at the headquarters to exchange resources conveniently without exposing
these resources to other Internet users.
Port Forwarding
This function enables external users to access FTP and other services within the LAN.
Parental control
Set an Internet access schedule for the client devices on the CPE network, and define which
websites the client devices can and cannot visit.
To manage parental control, click Set, then set an Internet access schedule and specify the
website blacklist.
4.5 System
In this section, you can quickly view device information, reboot or reset your device, modify
the login password, and more.
Device information
You can view device information in this tab, including IMEI, software version, and MAC
address.

15
Login password
Enter your current password, and set a new one. The new password must be 4 to 16
characters long.
System time
Manage the time zone in this tab.
TR-069
This is a protocol for communication between CPE and an Auto Configuration Server (ACS)
that provides secure auto-configuration as well as other CPE management functions within a
common framework.
Backup & restore
This feature allows you to back up the current device configuration, or restore the device to a
previous configuration by importing the backup configuration file.
Restart & reset
This function enables you to restart or factory reset the CPE.
If the CPE does not work properly, you can try restarting the CPE to solve the problem.
If you can't access the Internet for unknown reasons, or forget the login password, you can
restore the CPE to factory settings. To reset the CPE, you can also use a paperclip to press
the reset button on the CPE for 3 seconds.
Firmware update
Click Check for update, and the CPE will detect the current software version. If a new version
is available, you can click Update to upgrade the software.
NOTE
Do not power off the device during the upgrade process. Otherwise, it may be
damaged.
