Configuring PPP Profile Settings
• Profile Name: Enter a profile name when the text box
is empty.
• Dial-up Number/P
PP 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 mod
e for obtaining the
access point name (APN) and IP address. If the service
provider provides the releva nt parame ters, 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 automa
tically 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 d
evice 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.
• Di
sabled: 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
WL
AN, 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 acces sing the W LAN, 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.
• WP
A2-PSK: It is a more secure version of WPA-PSK
and it supports the IEEE 802.11 standard.
• WP
A Encryption Algorithm: TKIP, AES, TKIP+AES.
• WP
A Pre-Shared Key: You can enter a 64-character
hexadecimal value or 8-63-character ASCII value as
the k
ey. The ASCII value contains all characters that
can be entered through the PC keyboard, and the
hexadecimal value contains numbers of 0-9 and
chara
cters of A-F. For example, you can enter the
ASCII
value of 1234abcde as the key.
• Networ
k 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 Priva cy (WEP) is a 64-bit or 128 -bit
data encryption method. The 128-bit WEP encryption
provides higher security level.
• Network ke
y 1: You can enter 5 ASCII characters or
10-character hexadecimal numeral to form a 64-bit key.
Y ou can also enter 13 ASCII character s or 26-character
hexadecimal numeral to form a 128-bit key.

N. DHCP automatically assigns IP addresses to
the network devices. If you are using the DHCP
server, you need to do the configurations on the PC
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.
• S
ubnet 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.
• DH
CP 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.
Page 18
WLAN Settings
14
• 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 Le
ase 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 di sconnected f rom the net work,
the server assigns the IP address to another device.
Thus, the IP address is not wasted.
Note
• The S
tart IP Address must be smaller than
or equal to the End IP Address.
• If the DHCP Se
rver is Enabled, the
configurations of Start IP Address, End IP
address, and DHCP Lease Time are valid;
otherwise, you cannot configure them.

5Troubleshooting
What to do if a PC in the LAN cannot access the
Internet?
• If the power indicator is off, you need to check whether
the power adapter is normally connected.
• If the signal strength indicator is off, you need to check
wheth
er the area is covered by the network.
• 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
Settings
".
• 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.
• 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
"
Configuring PPP Profile Settings" for details.
• 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
Connection
".
• Check whether the driver of the network adapter is
correct
ly installed.
• If the preceding methods cannot solve the problem,
consu
lt you service provider.
What to do if a PC in the WLAN cannot access the
WLAN?
• If interferences or shie lds near the device exist, y ou can
adjust the position of the device. When the signal
strength is strong, you can move to the next step.
• Check and record the following data on the network
adapter
of your PC: SSID, WEP type, and key.
• 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. Otherwis e, 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?
• Make sure that the two devices work on the same
channel. For details, see "
Selecting a WLAN
Channel
".
Page 28

• 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".
When the signal strength is normal, what to do if
