Quick Setup to access the welcome page. Click
Next to configure the PPP profile settings.
Configuring PPP Profile Settings
•Profile Name: Enter a profile name when the text box
is empty.
•Dial-up Number/PPP User Name/PPP Password:
Enter these three parameters provided by the internet
service provider (ISP). The dial-up number is used to
initiate the network call; the PPP user name and PPP
password is used to obtain the service authorization
provided by the ISP.
•APN/IP Address: Select the mode for obtaining the
access point name (APN) and IP address. If the service
provider provides the relevant parameters, select Static
and enter their values. Otherwise, select Dynamic and
the device automatically obtains them.
Configuring PPP Dial-up Settings
PPP Connection: Select the dial-up access mode.
•Auto: The device automatically connects to the Internet
and does not disconnect when no data is transmitted.
•On Demand: The device automatically connects to the
Internet when data transmission exists. When the
duration of no data transmission exceeds the maximum
idle time, the device disconnects the Internet
connection.
•Manual: The device connects to the Internet after you
click Connect on the connection page. For details, see
"Accessing the Internet".
PPP Authentication: This service is provided by
your ISP. For details, consult your ISP.
Configuring WLAN Settings
(Name) SSID: Enter a name for your wireless local
area network (WLAN).
• The service set identifier (SSID) is used to identify a
WLAN. A PC and the wireless device can perform
normal data communication only when they have the
same SSIDs. To ensure the WLAN security, do not use
the default SSID. You can enter a character string as
the SSID, such as MyHome.

Quick Setup
8
SSID Broadcast: Enable or disable the SSID
broadcast.
•Enabled: The device broadcasts the SSID of the
WLAN and users can easily access the WLAN. In this
case, unauthorized users can also access the WLAN
because the SSID is broadcasted.
•Disabled: The device does not broadcast the SSID of
the WLAN. Before accessing the WLAN, a user must
obtain the SSID of the WLAN. In this case, the WLAN
security is improved.
Note
For the convenience of users accessing the
WLAN, you can select Enabled for SSID
Broadcast when you configure the WLAN
setting. After the setting, you can select
Disabled to improve the WLAN security.
Configuring WLAN Encryption
To access the WLAN, you must set the wireless
security key on your PC to be the same as that of the
wireless device.
No Encryption
• For the convenience of users accessing the WLAN, you
can select NO ENCRYPTION for the Encryption Mode
when you set up a WLAN. It is not recommended to
select this option in daily use.
WPA-PSK/WPA2-PSK
•WPA-PSK: It is a 256-bit data encryption method that
can automatically change the key.
•WPA2-PSK: It is a more secure version of WPA-PSK
and it supports the IEEE 802.11i standard.
•WPA Encryption Algorithm: TKIP, AES, TKIP+AES.
•WPA Pre-Shared Key: You can enter a 64-character
hexadecimal value or 8-63-character ASCII value as
the key. The ASCII value contains all characters that
can be entered through the PC keyboard, and the
hexadecimal value contains numbers of 0-9 and
characters of A-F. For example, you can enter the
ASCII value of 1234abcde as the key.
•Network Key Rotation Interval: It is used to set how
long a network key is dynamically changed. By default,
it is 0. To disable this function, you can set the value to
0 or null.
WEP
• Wireless Equivalent Privacy (WEP) is a 64-bit or 128-bit
data encryption method. The 128-bit WEP encryption
provides higher security level.
•Network Key 1: You can enter 5 ASCII characters or
10-character hexadecimal numeral to form a 64-bit key.
You can also enter 13 ASCII characters or 26-character
hexadecimal numeral to form a 128-bit key.

Wireless Configuration
The wireless configuration allows your PC to connect
to the device through the wireless network. If you
need only the Ethernet to connect your PC, you can
skip this part.
Configuration Requirements
• To set up wireless network connection, your PC must
be configured with the WLAN adapter that supports the
IEEE 802.11 b/g protocol.
• If the encryption function is enabled, you need to
ensure that all PCs connecting to the device use the
same key as that of the device.
• For the use of WLAN adapter, refer to the WLAN
adapter user guide provided by the manufacturer.
• For the encryption configurations, see "Configuring
WLAN Encryption".
• For SSID parameters configuration, see "Configuring
WLAN Settings".
