The wireless configuration allows your PC to connect to the device through the wireless network. If you need only the Ethernet to connect your PC, you can skip this part.
Configuration Requirements
• To set up wireless network connection, your PC must be configured with the WLAN adapter that supports the IEEE 802.11 b/g protocol.
• If the encryption function is enabled, you need to ensure that all PCs connecting to the device use the same key as that of the device.
• For the use of WLAN adapter, refer to the WLAN adapter user guide provided by the manufacturer.
• For the encryption configurations, see "Configuring
WLAN Encryption".
• For SSID parameters configuration, see "Configuring
WLAN Settings".

WLAN 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.
• The Start IP Address must be smaller than
Note
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.

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 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 "
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 "
Connection".
• Check whether the driver of the network adapter is correctly installed.
• If the preceding methods cannot solve the problem, consult you service provider.
Configuring the Network
Mobile Network
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?
