Question about Arris SB5100 SURFboard DOCSIS 2.0 Cable Modem (50120900100)

Need to hook up Belkin G wireless router to Motorola SB5120

I just dumped my very unreliable DSL modem and got a cable modem (Motorola SB5120). The new cable modem doesn't have as many ports on the back as the DSL did.

The Motorola cable modem has an Ethernet port and a USB port. That's all, except for the cable coax and the power supply, of course.

Between computer, modem, and router, which cables go where?

Thanks.

    Hello, glad to find this post, I'm also in need of connecting a router to use my laptop wi-fi...but I don't see mention of connecting the router itself in this scenario. My Cable connection is fine between modem and host pc, and need to know is connecting the router as simple as hooking it to the USB port of the Modem? am new to this, so please excuse any ignorance 8^)

Plug your cable line into your modem, make sure it's tight, but don't use a tool. Next plug the ethernet line from the modem to your PC ethernet port. Then plug in your power to the modem. Allow your modem to sync. Don't use the USB line at all. Do not even hook it up unless your computer doesn't have a working ethernet line. Don't run the disk either, it will only install the modem driver that is only used if you use USB.

If you have issues connecting after that, you may have to go into your ethernet adapter settings and make sure that it is using DHCP. DSL usually uses a different setting (PPP I think) and you will not be able to connect.

By the way, excellent choice in modems.

Check your connections:

DSL-modem to telephone-jack (or cable-modem to cable-jack).

Ethernet cable from DSL-modem (or from cable-modem) to WAN port on your router.

Ethernet cable from LAN port on router to WAN port on your Airport.

Cut the power to the Airport, and then plug it back in, so that it restarts.

How to reset moorola modem sb1520 surfboard


hi, to reset the modem follow these steps.

step 1 : Turn the Motorola Surfboard SB5120 Cable Modem so that the back of it is accessible to you. There's no need to disconnect any of the cables.

step 2 : Find the "Reset" button on the modem. It's a small recessed button located between the USB port and the cable outlet.

step 3: Use a pointed instrument to push the button. Hold it for 10 to15 seconds to allow time for the modem's indicator lights to go off.

step 4 : Release the Reset button. The lights will gradually begin to come on as the modem connects to the communications channels between the cable provider, the computer and the Internet provider. When all the connections are made, the lights will stablize.

step 5 : Release the Reset button. The lights will gradually begin to come on as the modem connects to the communications channels between the cable provider, the computer and the Internet provider. When all the connections are made, the lights will stablize.

Cannot set up Motorola Surfboard SB5120 modem


This usually means something is not correct with your incoming signal. If your cable wire into the modem is being run off an amplifier in the wall this could be effecting your service. If the signal is too strong the modem won't be able to communicate for internet.

You could check the incoming wire to see if it is running off an amplifier. If it is you would need to run a new line that is not on the amplifier. I would recommend comcast coming out to check the signal frequency and make the necessary adjustments.

Connect Modem to Laptop


yes. you plug it in. you plug your cable or DSL line in. Then if they have provided you with a USB A-B (like a printer cable) then you go from the back of the modem to the USB port of your laptop.
