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.
Quick Setup8SSID 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 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 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 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.

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
WLAN Settings 174Advanced Settingsfrom 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.

256TroubleshootingWhat 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 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, consult you service provider.What to do if a PC in the WLAN cannot access the WLAN?• 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.• 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. 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?• Make sure that the two devices work on the same channel. For details, see "Selecting a WLAN Channel".
26• 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 the downloading rate is low?In this case, you need to set the value in the registry as follows:• Choose Start > Run.•Enter regedit in the Open text box and then click OK.• Select parameters in the following directory: \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\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.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). • 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.
