5. If the LAN LED is still off, follow this step only if the satellite router is connected to a hub,
router, or other network device (that is, not connected directly to the computer). Connect
the computer directly to the satellite router (to bypass the network device) as follows:
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 computer that was
connected to the satellite router.
If the LAN LED is still off, contact your service provider.
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 46
• Receive LED is off on page 47
• System LED is off on page 47
If the satellite router is not operating normally and the Transmit LED is off, follow these steps:
1. Check the router's cable connections.
Make sure the cable connections 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 your service provider.
