Advanced Settings
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.
• 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 Disabled 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.
说明
• 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.

6Troubleshooting
What to do if a PC in the LAN cannot access the
Internet?
1The power indicator is on, and the device is
normally connected with the power adapter. If
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, you need to reset the device to factory
defaults.
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
22
management page when the PC obtains the IP
address automatically.
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\CurrentCo
ntrolSet\Services\Tcpip.
4Choose Edit > New > DWORD Value.
5Rename New Value #1 to TcpWindowSize.
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.
