1.1 About this Help
This help is designed to guide you through the configuration of the WiMAX CPE
(Customer Premises Equipment) for accessing the network services and only for
reference. The actual functions are subject to your product purchased.
Generally, the WiMAX CPE will be referred to as the CPE in this help. And the
following symbols are used in this help:
A note provides additional information about a topic.
A tip provides an alternative method or shortcut to perform an action.
A caution warns you about potential problems or specific precautions that need to be
taken.
1.2 The CPE Overview
The WiMAX CPE is a gateway that is applicable to the WiMAX (Worldwide
Interoperability for Microwave Access) network. Generally, with the CPE, you can build
a secure home or small office network with easy setup and configuration through
WiMAX wireless Internet access to enjoy various broadband network services easily and
conveniently in areas covered by the network, you can make and receive Internet calls
working with the VoIP (Voice over IP) communication capabilities of the CPE, and you
can also configure firewall and various filtering for secure Internet access, as well as host
of other features.
You can operate and manage the CPE through the Web-Based Utility, which is a web
browser-based configuration interface that allows easy device setup, configuration and
management via Internet browser. It provides the interfaces for browsing, configuring,
managing and maintaining the CPE.
1.3 Accessing the Web-Based Utility
Take the Windows XP operating system and the Internet Explorer 7.0 for example, to
access the Web-based utility, refer to the following steps:
Step 1
Step 2
Make sure the hardware of the CPE is properly connected (refer to the Quick Start).
Configure the IP address of the computer. Make sure that the IP address of the computer
and the IP address of the CPE are in the same network segment.

Step 4
1 Getting Started
By default, the IP address of the CPE is 192.168.1.1 and the subnet mask is
255.255.255.0, and the IP address of the computer must be within the range 192.168.1.2
to 192.168.1.254 to be compatible with the CPE.
Run the Internet Explorer, enter the IP address of the CPE (http://192.168.1.1 by default)
in the address bar, and then press Enter.
Enter the user name and password in the login windows that opens and select Login.
Both the initial user name and password are user.
It is highly recommended you change the default user name and password, and see “5.1
Maintaining the User Account” for reference.
Step 5
After the user name and the password are verified, you can perform operations through
the Web-based utility.

2 Configuring Basic Settings
2.1 WAN
A WAN (Wide Area Network) is an outside connection to another network or the Internet.
With correct WAN settings, network devices such as computers and telephones on the
LAN (Local Area Network) side can be connected to another network or the Internet
through the CPE.
2.1.1 Working Mode
When connecting to a WAN, the CPE supports the following two working modes with
respect to connectivity between the WAN and the LAN:


Routing mode, the CPE provides typical routing functionality between the WAN
side and the LAN side. Based on packet information, the CPE searches for a route
through which the packets are sent to the destination IP address.
Bridging mode, the CPE provides only bridging functionality. The CPE only
transparently transmits packets.
2.1.2 Connection Type
When connecting to a WAN, the CPE supports the following three connection types:



Dynamic IP address, also referred to as DHCP (Dynamic Host Configuration
Protocol), the ISP (Internet service provider) assigns you a dynamic IP address
automatically each time you connect to the Internet.
Static IP address, the ISP provides you a fixed IP address and related information
(Network Mask, Gateway IP address, and DNS address).
PPPoE (Point-to-Point Protocol over Ethernet), the ISP provides you a PPPoE
connection information. The IP address is usually allocated automatically.
2.1.3 Configuring the WAN
For the sake of brevity, an abbreviated style for menu commands is used throughout this
help. For example, "Select Basic > WAN" means "Select WAN from the Basic menu".
Step 1
Step 2
Step 3
To configure the WAN settings, refer to the following steps:
Access the Web-Based Utility.
Select Basic > WAN in the navigation tree.
Select Route or Bridge from Mode drop-down list box to set the CPE to work in routing
mode or in bridging mode.

Step 4
2 Configuring Basic Settings
Select the connection type and configure the connection parameters and settings for the
CPE according to the configuration information provided by your ISP.
Only in the bridging mode you can enable the VLAN (Virtual Local Area Network)
feature.
Step 5
1. If you select Static, enter the corresponding parameter values provided by the ISP in
the IP Address, Subnet Mask, Default Gateway, Primary DNS Server, and
Secondary DNS Server text boxes.
2. If you select PPPoE, enter the user name and password provided by the ISP, and
select the dial-up method in the Dial-up method drop-down list box.
Two dial-up methods are provided: Automatic and Manual Dial. If you select
Manual Dial, you need to select Connect to set up a dial-up connection.
3. If you have set the CPE to work in routing mode, you have to select the NAT
(Network Address Translation) type.
The NAT feature is enabled to facilitate the translation of IP addresses when the CPE
works in the routing mode. Through NAT, the host IP address of a LAN can be
effectively hidden. Thus, the security of the intranet is ensured. Two NAT types are
provided: NAPT (Network Address Port Translation) and CONE NAT.
Select Apply to save the configuration.
----End
2.2 LAN
A LAN (Local Area Network) is a shared communication system to which more than one
device are attached limited to the immediate area.
With correct LAN settings, network devices such as computers can share
communication on the LAN through the CPE.
2.2.1 IP Address and Subnet Mask
By default, the LAN parameters of the CPE are the following values: IP address of
192.168.1.1 with subnet mask of 255.255.255.0. You can change the IP address to
another individual IP address that is easy to remember, and make sure that IP address is
not used by other device on your network. If you change the IP address of the CPE, you
have to access the Web-Based Utility with the new IP address.
To change the IP address and subnet mask of the CPE, refer to the following steps:
Step 1
Step 2
Step 3
Step 4
Step 5
Step 6
Access the Web-Based Utility.
Select Basic > LAN in the navigation tree.
Select DHCP tab page.
Enter a new individual IP address in the IP Address text box, make sure that IP address
is not used by other device on your network.
Enter the subnet mask in the Subnet Mask text box (for example, 255.255.255.0).
Select Apply to save the configuration.

2.2.2 DHCP
DHCP (Dynamic Host Configuration Protocol) allows individual clients to obtain
TCP/IP configuration automatically at startup from a server.
You can configure the CPE as a DHCP server or disable it when the CPE is working in
the routing mode. When configured as a DHCP server, the CPE provides the TCP/IP
configuration automatically for the LAN clients that support DHCP client capability. If
DHCP server service is disabled, you must have another DHCP server on your LAN, or
else each client must be manually configured.
The CPE is pre-configured with a pool of IP addresses for the DHCP clients (DHCP
Pool). With the DHCP server service enabled, you can change the start IP address and the
end IP address for the Pool or reserve the default.
To configure the DHCP settings, refer to the following steps:
Step 1
Step 2
Step 3
Step 4
Step 5
Step 6
Step 7
Access the Web-Based Utility.
Select Basic > LAN in the navigation tree.
Select DHCP tab page.
Select or clear Enable DHCP Server check box to enable or disable the DHCP server
feature of the CPE. If you disable the feature, go to Step 7.
Enter the start IP address and the end IP address.
Select the lease time that a client may use an IP address, the client will request a new IP
address after the time limit expires.
Select Apply to save the configuration.

2.3 WLAN
A WLAN (Wireless Local Area Network) links two or more devices over short distances
using wireless distribution method instead of traditional network cabling, typically
extending an existing wired local area network, and usually providing a connection
through an access point to the wider internet. A WLAN gives you the mobility to move
around within a local coverage area and still be connected to the network.
2.3.1 SSID
An SSID (Service Set Identifier) is a unique identifier that distinguishes one WLAN
from another. Wireless devices use the SSID to establish and maintain wireless
connectivity.
The CPE can support two separate SSIDs. This logically divides the access point into
two virtual access points within a single hardware platform.
You can assign different configuration settings to each SSID. Both the SSIDs are active
at the same time; that is, client devices can associate to the access point using either of
the SSIDs. This enables the separation of wireless applications based on security and
performance requirements. For example, you could enable encryption and authentication
on one SSID to protect private applications and no security on another SSID to maximize
open connectivity for public usage.

2 Configuring Basic Settings
Besides security settings, you can also assign the following two important settings to
each SSID:

SSID broadcasting.
In some cases, such as public Internet access applications, you can broadcast the SSID to
enable user radio cards to automatically find available access points. For private
applications, it is generally best to not broadcast the SSID for security reasons. Multiple
SSIDs means you can mix and match the broadcasting of SSIDs.

Maximum number of client associations.
You can set the number of users that can associate via a particular SSID, which makes it
possible to control usage of particular applications. This can help provide a somewhat
limited form of bandwidth control for particular applications.
2.3.2 Wireless Security
The CPE supports different levels of security:

None
No security, and not recommended.


WEP
Not recommended as reliable, but can be used until your device can be upgraded to
support WPA, and it is still a lot better than nothing.
WEP (Wired Equivalent Privacy) is the encryption type for wireless security in early
ages, but it has been found to be not strong enough to keep data secure and can be broken
rather easily, and it has better replacements of WPA.
Two methods of authentication can be used with WEP: Open and Shared. In Open, any
device can authenticate to the AP. In Shared, only devices with the WEP key can
successfully authenticate.
Most devices that support WEP can be firmware/software upgraded to WPA. Do not use
WEP unless some devices cannot be upgraded to support WPA.
When using WEP, you can use a secure encryption key with random characters that will not
be break easy and change it regularly to increase the security of your network.

WPA (Wi-Fi Protected Access)
In a broad sense, WPA is now in a second generation, referred to as WPA2. Unless
otherwise specified, this document uses "WPA" to refer to both, but when corresponding to
WPA2, "WPA" is referred to as the first generation in a narrow sense.
WPA is a modified version of WEP, which changes the effective key quite often. It is
much more secure than WEP, and it is currently believed more secure as long as you use
a good password.
WPA2 is a second-generation implementation based on new encryption technology, and
is supposedly be more secure than WPA.

2 Configuring Basic Settings
The CPE supports the following WPA encryption types to protect your data being
transferred from the device such as the computer to the CPE and the Internet:
 WPA-PSK
 WPA2-PSK
 Mixed WPA2/WPA-PSK
WPA-PSK and WPA2-PSK is the simplification of WPA and WPA2, designed for home
and small office networks that do not require the complexity of an RADIUS
authentication server.
Mixed WPA2/WPA-PSK may operate in a network that mixes WPA and WPA2 clients.
WPA Encryption Technology
The CPE supports the following WPA encryption technologies for each encryption type:
 TKIP
 AES
 TKIP+AES
WPA uses the TKIP (Temporal Integrity Protocol) which changes key automatically,
and WPA2 is built on WPA and uses the stronger AES (Advanced Encryption Standard)
which is supposedly be more secure.
However, some devices allow WPA with AES and WPA2 with TKIP. Thus AES is
optional in WPA and is mandatory in WPA2, and TKIP is optional in WPA and is
mandatory in WPA2.
TKIP is not directly comparable to AES; TKIP is an integrity check, AES is an encryption
algorithm. AES is preferred.
When using TKIP+AES, the device will attempt to use AES for higher security if
available and fall back to TKIP if not. This setting offers the most compatibility but will
not guarantee a higher level of encryption in case a device falls back to TKIP.
2.3.3 WPS
WPS (Wi-Fi Protected Setup) is a WLAN protocol that is used to facilitate the
establishment of secure wireless connection for wireless home networks.
The WPS protocol is to simplify the process of configuring security on wireless
networks and automatically configure a wireless network with a network name (SSID)
and strong WPA data encryption and authentication supported by all Wi-Fi certified
devices for home users who know little of wireless security.
To add a new device to the WLAN, WPS can be used in the following two methods:

PBC (Push Button Configuration)
The PBC method is to be used if the wireless client device has a WPS button (either an
actual one or a virtual one).
 PIN (Personal Identification Number)
PIN is a mandatory method of setup for all WPS certified devices. It works two ways on
both the wireless client and on the CPE: use the PIN code generate by the CPE or use the
PIN code pre-defined by the client.
