Check your Ethernet connection
If your Ethernet light doesn't light up, try the following:

1. Verify you're using the provided yellow Ethernet cable and check the connections to the computer's Network Interface Card (NIC)/Ethernet port and the Ethernet port on the back of the Motorola modem.
2. If another Ethernet (RJ-45) cable is available, swap out cables to make sure yours isn't defective. Make sure the cable isn't a crossover type cable. If the cable is defective, contact Technical Support for a new RJ-45 patch cable.
3. Go to Device Manager to make sure the NIC is enabled. If already enabled, disable the NIC and re-enable.

Note: If you are using an Ethernet (RJ-45) cable not provided by AT&T, make sure it is a straight-through cable and not a crossover cable. A crossover cable will give a green Ethernet light, but prevents surf.
