Having trouble? Many issues can be resolved in three simple steps:
1. Check your connections.
• Verify that cables, cords, and modem filters on all devices are connected as specified in
steps 1A–1C. Cables usually make an audible “click” when secure.
• On the Motorola modem, if using a dual-port filter, ensure the filter is plugged into the wall jack
and not the Gateway, that the green Data Cable is plugged
into the DSL port on the filter, and the
Phone Cable is connected to the "Phone" port on the filter.
• Be sure you are using the supplied Power Cord.
• Verify that the Motorola modem is set up correctly by connecting it directly to a computer
to access the Internet.
2. Power down, power up.
Shut down your computer, and unplug the black Power Cord and any other devices from the back
of the Gateway and Motorola modem. Wait 15 seconds and then plug devices back in, making sure
the power lights are on. Then, turn your computer back on.
3. Wait for blinking indicator lights.
Wait for the Motorola modem, Wireless Gateway and Ethernet WAN lights to turn solid green.
The wireless light on the Motorola modem should blink green.
