Using the Management Page
•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.
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
Disable to improve the WLAN security.
Configuring the 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 802.11 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
Accessing the Internet

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.

connecting with the device. For details, see
"Configuring the Network Connection".
•IP Address: The default IP address of the device is
192.168.1.1.
•Subnet Mask: The combination of the subnet mask
and IP address enables the flexible sub netting. By
default, the subnet mask is 255.255.255.0.
•DHCP Server: It is used to assign IP addresses
dynamically. If the DHCP server is Enabled, it can
automatically assign IP addresses for PCs. It is
recommended to select Enabled for the DHCP server.
•Start IP Address/End IP Address: It is used to define
the IP address range that the host can use during the
IP address assignment. For example, in the network
segment 192.168.1.0/24, the default IP address of the
device is 192.168.1.1. The host IP address can range
from 192.168.1.2 to 192.168.1.254. The minimum
range is a single IP address.
•DHCP Lease Time: The DHCP server automatically
assigns an IP address to each device connected to the
network. When the leased time expires, the DHCP
server checks whether the device is connected to the
network. If the device is disconnected from the network,
the server assigns the IP address to another device.
Thus, the IP address is not wasted.
Note
•The Start IP Address must be smaller than
or equal to the End IP Address.
• If the DHCP Server is Enabled, the
configurations of Start IP Address, End IP
address, and DHCP Lease Time are valid;
otherwise, you cannot configure them.

1If the power indicator is off, you need to check
whether the power adapter is normally
connected.
2If the signal strength indicator is off, you need to
check whether the area is covered by the
network.
3If 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 Settings".
4If 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.
5You 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 "Configuring PPP Profile
Settings" for details.
6If 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 Connection".
7Check whether the driver of the network adapter
is correctly installed.
8If the preceding methods cannot solve the
problem, please consult you service provider.
What to do if a PC in the WLAN cannot access the
WLAN?
1If 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.

Troubleshooting
2Check and record the following data on the
network adapter of your PC: SSID, WEP type,
and key.
3Check and record the following data on the
device: SSID, WEP type, and key.
4Compare 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.
What to do if I forgot the IP address of the LAN
interface?
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.
What to do if bridging between two devices is
unsuccessful?
1Make sure that the two devices work on the
same channel. For details, see "Selecting a
WLAN Channel".
2Make sure that the MAC address of one device
is in the peer MAC address list of the other
device. For details, see "WLAN Bridge".
When the signal strength is normal, what to do if
the downloading rate is low?
In this case, you need to set the value in the registry
as follows:
1Choose Start > Run.
2Enter regedit in the Open text box and then click
OK.
3Select parameters in the following directory:
\HKEY_LOCAL_MACHINE\SYSTEM\CurrentC
ontrolSet\Services\Tcpip.
4Choose Edit > New > DWORD Value.
5Rename New Value #1 to TcpWindowSize.
24
6Right-click TcpWindowSize and then select
Modify.
7Select Decimal and enter 65535 in the Value
data text box, and then click OK.
8For the DWORD Value of DefaultRcvWindow,
do the same operations as that of
TcpWindowSize.
