a) Disconnect the Ethernet cable from the device.
b) Using an Ethernet cable you know is good, connect the satellite router LAN port directly
to the Ethernet port on the computer.
This temporarily bypasses the Ethernet device as a way to help determine where and what
the problem is.
c) Check the router's LAN LED.
If the LAN LED is on, but was off before you made this direct connection, there is probably
a problem with your network device or the connections to it. Check those connections. If the
LAN LED is still off after checking the connections, contact the manufacturer of the network
device for assistance.
6. If you have not found any problem so far, but the LAN LED is still off, power cycle the
router again.
7. If the LAN LED is still off, power cycle the Ethernet device according to the device
documentation.
8. If the LAN LED is still off, restart the computer.
9. If the LAN LED is still off, try connecting the satellite router to another computer.
If the front panel LAN LED is now on, there may be a problem with the customer's computer
that was connected to the satellite router.
If the LAN LED is still off, contact Installer Support.
If a device other than a computer is connected to the satellite router, the System Control Center
is probably never accessible. However, you can troubleshoot based on the following LED
conditions. For details, go to the listed page.
• Transmit LED is off on page 100
• Receive LED is off on page 101
• System LED is off on page 101
If the satellite router is not operating normally and the Transmit LED is off, follow these steps:
1. Check all cable connections, from the satellite router to the outdoor satellite antenna, and
tighten any connections that seem loose.
Make sure cable connections to the router are secure (properly aligned—not cross threaded;
finger tight with no play).
Note: The router may operate correctly when first installed even if the transmit and
receive cable connectors are not adequately tightened. However, problems could develop
later. Therefore, correct operation of the satellite router is not an indication that the
cables are adequately tightened.
2. If the LED is still off, check the cable for breaks.
3. If the problem persists, contact Installer Support.
