DHCP Settings Click to access the DHCP Setting page, you can set the mode for assigning IP addresses in a LAN. DHCP automatically assigns IP addresses to DHCP 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. 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. • 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. Advanced Settings • 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. 15 5 Security Settings (Optional) Click Security, you can configure the advanced security settings. Firewall Switch Your device has a true firewall that controls the incoming and outgoing data flow and protects your computer from illegal intrusion.

Click Select Enabled /Disabled for DMZ Status to enable or disable the DMZ service. Enter the local IP address of the computer that is specified as a DMZ host. Click Apply. UPnP Settings The Universal Plug and Play (UPnP) service allows other network users to control your device’ s network features to realize the intelligent interconnection. Click Select Enabled/Disabled for UPnP Status to enable or disable the UPnP service Click Apply. Remote Management The remote web management allows the access and control of the device either from the home network or from the Internet. Security Settings (Optional) However, the DMZ computer is not protected by the firewall. It is vulnerable to attack and may also put other computers in the home network at risk. Only one computer can be specified as a DMZ host at a time. 19 Remote Management When you are on a trip, you can maintain your device through the remote web management service. It also allows your ISP to help you solve the device problems from a remote location. 20 Click Select Enabled or Disabled for Remote Status to enable or disable the service. Enter the IP address that can access and control your device. Click Apply. 6 Troubleshooting What to do if a PC in the LAN cannot access the Internet? The 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. If the signal strength indicator is off, you need to check whether 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 correctly installed. If 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 21 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: 22 Choose Start > Run. Enter regedit in the Open text box and then click OK. Select parameters in the following directory: \HKEY_LOCAL_MACHINE\SYSTEM\CurrentCo ntrolSet\Services\Tcpip. 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. 7 Warnings and Precautions Electronic Device • Turn off your device near high-precision electronic devices.
