Quick Setup
PPP Authentication: This service is provided by
your ISP. For details, consult your ISP.
Configuring PPP Profile Settings
• Profile Name: Enter a profile name when the text box
is empty.
Configuring WLAN Settings
• 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.
(Name) SSID: Enter a name for your wireless local
area network (WLAN).
1
• 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.
• 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.
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.
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.
• 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.
• 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.
For the convenience of users accessing the
WLAN, you can select Enabled for SSID

it is 0. To disable this function, you can set the value to
0 or null.
WEP
Configuring WLAN Encryption
• Wireless Equivalent Privacy (WEP) is a 64-bit or 128-bit
data encryption method. The 128-bit WEP encryption
provides higher security level.
To access the WLAN, you must set the wireless
security key on your PC to be the same as that of the
wireless device.
• 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.
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.
Validating Quick Setup
The last page of the wizard displays all the settings
you have configured.
WPA-PSK/WPA2-PSK
• WPA-PSK: It is a 256-bit data encryption method that
can automatically change the key.
• To accept the settings, click Finish.
• To change the settings, click Back.
• To quit the settings, click Cancel.
• WPA2-PSK: It is a more secure version of WPA-PSK
and it supports the IEEE 802.11 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.

• 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

What to do if a PC in the WLAN cannot access the
WLAN?
• If the power indicator is off, you need to check whether
the power adapter is normally connected.
• If interferences or shields near the device exist, you can
adjust the position of the device. When the signal
strength is strong, you can move to the next step.
• If the signal strength indicator is off, you need to check
whether the area is covered by the network.
• Check and record the following data on the network
adapter of your PC: SSID, WEP type, and key.
• If the area is covered by the network, you need to
check whether the network mode is correct. For
