cable, possibly one that came with a cable modem starter kit from your cable 
service provider.  If you don’t have a coaxial cable, you can get one at most 
electronics stores.  You want one with a screw-in male F connector at each 
end, with a length that works for your installation.

  If you don’t have an available cable TV cable or wall jack, use a coaxial “T 

adapter” or “splitter” available from most electronics retailers (see example at 
right). Make sure you get one designed for cable modems and/or cable TV.  
These typically have one female IN jack and two female OUT jacks.  You can 
disconnect a live cable from your TV set-top box and screw it into the IN jack of 
the splitter.  Then connect one coaxial cable from an OUT jack to your TV set-
top box and another coaxial cable from the other OUT jack to your cable 
modem.  You can see that this approach uses one splitter and 2 additional 
coaxial cables, each of which has male connectors on each end.  Some 
electronics retailers carry the Zoom Cable Modem Connection Kit which has an 
excellent splitter and 2 coaxial cables packaged together at a reasonable price.  
You can also purchase splitters and coaxial cable separately if you prefer to do 
that, perhaps because you need a special length of coaxial cable.

Connect the supplied Ethernet cable between the cable modem’s yellow LAN 
jack and a computer’s Ethernet jack.  We recommend that you do this even if you 
later plan to connect the cable modem to a router.

Connect the Zoom power cube between the Zoom cable modem and a live 
power jack. Make sure the cable modem’s Power Switch is ON.

“Now that your cable modem is connected, do this.”

 below. 

 
 
Now that your cable modem is connected, do this. 
 

It normally takes 5 to 30 minutes to establish an Internet link the first time a cable modem 
connects to a cable service provider.  This allows the cable modem to connect to the 
appropriate channels for communication. You’ll see the DS, US, and/or Online modem 
lights on your cable modem flashing until the Online light stays steady green to signal 
success. 

After the cable modem connects to your cable service provider, open your Web browser 
on the computer that’s connected to your cable modem.  Then refresh the screen or try to 
go to a Web site.  Many service providers, including Comcast, typically bring your 
browser to a registration page.  In that case, follow the instructions on this registration 
page to register your modem.  

If no web page appears after opening your browser, you need to call your cable company 
to register your modem.  Below is a list of some major cable service providers’ phone 
numbers to call to activate your cable modem.  Note that this list is subject to change.
