Once your cable modem is registered either online or through a conversation with 
someone at your cable service provider, your service provider will provision your cable 
modem service. Typically this takes less than 5 minutes, but in some cases this may take 
up to 30 minutes to complete. 

To check that your cable modem is working, open your browser and go to a familiar Web 
site. If it works, 

Congratulations!

 Installation is complete for a single PC.  If you want to 

connect your cable modem to a router, please continue directly below.  If your cable 
modem is NOT working, see 

Troubleshooting Tips

 on the back of this Quick Start

 

for 

help.  
 

 
How to connect your cable modem to a router instead of a 
computer. This connection is optional, done after the cable modem 
is working with a computer. 

 

1

 

The router should not be plugged in or powered up. If it is, unplug it. 

2

 

Unplug the cable modem’s Ethernet cable from your computer and plug it into 
the Router’s WAN port.

 

3

 

Power-up the router. Make sure the modem’s Power button is ON. Wait for the router 
to complete its power-up sequence.  

4

 

The

 Link 

light of the modem should be lit to show the Ethernet connection. You’ll see 

the 

DS 

(downstream), 

US 

(upstream), and 

Online

 modem lights flashing until the 

Online

 light stays steady green to signal success. (

The Blue US/DS LEDs blink 

during negotiation of bonded channels, and become solid when negotiation is 
complete. If after several minutes the US/DS LEDs continue to blink

, this indicates 

partial service (at least one designated channel has not completed bonding). This 
does not generally affect performance, but your MSO may want to know so they can 

adjust their network.)

 

5

 

Follow your router’s instructions for setting up the router and connected devices. 

6

 

Using a computer connected to the router, open the computer’s browser and go to a 
website to check that the connection between your cable modem and router is 
working properly. If it works, 

congratulations

! Installation is complete. 

 

If the cable modem worked when connected to a computer but does not work when 
connected to a router, try the following: 
 

¾

  First try shutting down and restarting the router; if that doesn’t help, then try 

shutting down and restarting each computer connected to the router.  

¾

  Power off your cable modem, router and any computers connected to the 

router.  Power on the cable modem and allow it time to resynchronize with 
the cable system. Once the cable modem is synchronized with its online 
light steady green, power up your router, then power up any computers 
connected to your router.
