Nope, this is a modem only, of course you can connect your choice of wireless routers. Cheers.

Nope, this is a cable modem only. You can of course connect your choice of wireless router. cheers.

Not this one but I was reading that Moto has one combo unit modem/ router but the reviews are not that good and is more pricey ...

No it does not. You will need to plug this modem into a third party router i.e. Linksys, D-Link, Netgear

this model does not have a built in router.

No It Doesn't have a router as Walmart advertised, I am so glad my Apple Extreme Wireless Router Does have ports!!!!

no, this is a cable modem that will plug into your computer. If you want to be wireless you will need to buy the wireless router seperately

No. If you want to connect it to more than one computer you will need a router.

No - and you should never plug a computer directly into the modem - you are a sitting duck on the Internet, open to all kinds of automated port scans and other hack-attacks until you put your computer (or network) behind a NAT router. It&#39;s not a total security solution by any means - but to a &quot;hacker&quot; on the other side of earth - it&#39;s much better to have them stopped in their tracks at your router than able to directly access your PC . Since practically all of the home routers run some flavor of Linux (not Windows) - the Windows vulnerabilities hackers use to exploit ports on your PC become irrelevant. Note that it&#39;s possible to protect yourself without a router but you&#39;d better understand the ins/outs of a firewall or other advanced security appliance - and know how to deploy it.

Does the Motorola modem sb6121 have a router built in?

According to the spec sheet there is an "F" connector which means yes, coaxial cable can be connected to this modem. This would be expected since this is a cable modem.

Yes, there is a coax connection on this model.

No. The cable company usually supplies the coaxial cable

it does not come with a coax cable, you must provide your own.

The product does nto come with the Coaxial Cable.

there is no coaxal cable in this kit, must purchase seperate!!!

You will need to purchase the coaxial cable seperatly. Measure the distance from hook up to you computer to make sure you buy a long enough cable.

The coaxial cable is the one that comes through the wall and provides your cable service. This modem has the jack to connect that cable.

No. The coax is the cable your internet provider runs to you house.

Does this model have Coaxial Cable; I saw that there was only Ethernet and Power Cable in the Kit?

No, this is strictly a cable modem. Note - this is NOT compatible with dsl or Uverse.

Yes, I have Vonage and it goes through the Internet also.

No, If your on TWC you keep the TWC issued modem at no charge for your phone service and the SB6121 modem will now be your internet modem!!!

It has 3 plugs. 1 to hook coxial cable, 1 for the power cord and one for the ethernet cord that will plug to other divices such as a computer.
