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

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.

the Wireless Network Connection dialog box is  
displayed and requires the network key and  
confirmation. The value you entered must be the

Key of the device.  
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.

If your PC cannot run network applications through  
the device, you can set the computer to access the  
Internet unlimitedly by configuring the IP address of  
the computer in the demilitarized zone (DMZ).  
The Universal Plug and Play (UPnP) service allows  
other network users to control your device’s network  
features to realize the intelligent interconnection.

5Troubleshooting  
What to do if a PC in the LAN cannot access the  
Internet?  
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  
information about network mode, see "Mobile Network  
• Check and record the following data on the device:  
SSID, WEP type, and key.  
• Compare the recorded data, the SSID on the network  
adapter should be ANY or be the same as that on the  
device. The WEP type and key on the network adapter  
and device should be the same. Otherwise, you need to  
change the data on the network adapter.  
• If the indicator of the Ethernet interfaces blinks, the  
corresponding Ethernet interface is normally  
connected. If the indicator is off, you need to check and  
ensure that the related Ethernet connection is normal.  
What to do if I forgot the IP address of the LAN  
interface?  
You must configure the correct PPP user name and  
PPP password when you access the Internet through  
the device. Check whether they are correct, and see  
• If you forgot the IP address of the LAN interface, you  
can enter http://e.home and log in to the management  
page when the PC obtains the IP address  
automatically.  
• If the DHCP service is disabled and the PC obtains the  
IP address dynamically, the PC also cannot access the  
Internet. You can change the mode to manually assign  
an IP address. See "Configuring the Network  
What to do if bridging between two devices is  
unsuccessful?  
• Make sure that the two devices work on the same  
channel. For details, see "Selecting a WLAN  
Channel".  
• Check whether the driver of the network adapter is  
correctly installed.  
• If the preceding methods cannot solve the problem,  
consult you service provider.  
23  
 
 
• Make sure that the MAC address of one device is in the  
peer MAC address list of the other device. For details,  
see "WLAN Bridge".  
What to do if I cannot make or receive a call from  
a telephone connected to the device.  
• If the phone is working, you can connect it to a fixed  
line telephone network (PSTN).  
When the signal strength is normal, what to do if  
the downloading rate is low?  
• If a dial tone is heard when picking up the handset.  
• If the SIM card is correctly inserted.  
• Contact your service provider if problems remain.  
Only follow these instructions if you are

• Choose Edit > New > DWORD Value.  
• Rename New Value #1 to TcpWindowSize.  
• Right-click TcpWindowSize and then select Modify.  
• Select Decimal and enter 65535 in the Value data text  
box, and then click OK.  
• For the DWORD Value of DefaultRcvWindow, do the  
same operations as that of TcpWindowSize.
