Checking the connection to the Gigaset SE680 WiMAX
You can check whether the PC is correctly connected to the Gigaset SE680 WiMAX
modem. This can be done as follows:
ì Open the command prompt on the PC:
– Click on Start > Run.
–Enter cmd in the input field and click on OK.
The Command prompt window opens.
ì Check whether the Gigaset SE680 WiMAX modem responds with the ping com-
mand. Enter ping 192.168.2.1 and press Enter.
The PC now sends some test packets via this connection and checks whether the con-
nection partner responds. The connection partner may respond in the following ways:
u Reply from the IP address of your Gigaset SE680 WiMAX modem; statistics about
the connection are presented. If you receive these statistics, the connection to the
device is OK.
u The request exceeds the time limit; it was not possible either to send or receive
any packets. There is no physical connection between the PC and your Gigaset
SE680 WiMAX modem. Check the following points:
– Is the Ethernet cable between the Gigaset SE680 WiMAX modem and the PC
properly connected?
The LAN LED on the Gigaset SE680 WiMAX modem must light up.
– Has TCP/IP been properly configured on your PC?
If the Gigaset SE680 WiMAX modem has the IP address 192.168.2.1, your PC's IP
address must be between 192.168.2.2 and 192.168.2.254. The subnet mask
must be 255.255.255.0.
To find out the IP address of your PC, enter ipconfig in the command prompt.
If the Gigaset SE680 WiMAX modem has not responded successfully to the ping com-
mand, you need to adjust the network settings on the PC. To find out how to do this,
please read the document "Configuring the local area network" on the product CD.
If the Gigaset SE680 WiMAX modem has responded successfully to the ping command,
the network is configured correctly. If it is not possible to access the configuration pro-
gam of your Gigaset SE680 WiMAX modem, check and change the settings in your Web
browser. To find out how to do this, please read the next chapter.
