Cannot Access the System Control Center
Follow these steps if you cannot access the System Control Center after installation of the satellite modem.
1. If the modem is using a private IP address, conrm that DHCP is enabled on the computer.
This procedure is explained in Conguring a computer to use DHCP on page 39.
2. Open a web browser on a computer connected to the satellite modem.
3. In the browser address bar, type www.systemcontrolcenter.comor 192.168.0.1 and press Enter.
Note: Touse 192.168.0.1, the satellite modem must be congured for a private IP address, and DHCP must
be enabled on the computer.
If the System Control Center does not appear, continue with the remaining steps.
4. Make sure that the satellite modem is powered up. The Power and LAN LEDs should be continuously lit—except
that the LAN LED may blink if there is LAN activity.
5. Make sure the DC power cord adapter is securely attached to the satellite modem.
6. If the LEDs are off, make sure the Ethernet cable is securely attached to the satellite modem and the computer.
7. If you still cannot access the System Control Center,contact Hughes Customer Care for assistance.
Testing connectivity to the satellite
If you have problems connecting to the Internet, you can use the Connectivity Testpage to test connectivity between
the modem and the satellite. This connectivity test sends test messages on a loop from the modem to the satellite and
backto the modem, as shown in Figure 24: Satellite loopback connectivity test on page 34. If the test succeeds, it veries
that the modem can connect to the satellite.
