Question about Arris SURFboard SB5120 Modem

1 Answer

Usb to ethernet

For some reason when the modem was installed the guy connected it to the CPU with a USB cord. Now we are trying to set up a wireless router so we need to use the ethernet cable.

PROBLEM:
There is internet connection for a few minutes with the ethernet cable, but then it is lost completely. We can't get a connection to hold with the ethernet cable even though the network card and all other hardware is working fine. This keeps happening after several re-boots and resets of the modem. What is going on!

Thanks,

JRS

SOURCE: Motorola SB5120 Problem with ethernet cable

My PC is connected to my modem with my USB. Because I had to setup up my router, I needed to go through my Ethernet port. What I discovered was that the port on the modem was damaged - pins were misaligned an ethernet cable was yanked out of the socket. I realigned the pins with a screwdriver and that worked, but it's not an ideal solution.

Can't connect using usb cable


Try using Ethernet. That is always the recommended way to connect to the modem, and it works almost 100% of the time without having to install additional software or perform any additional configuration. If you must use USB for some reason then you will need to make sure you have the drivers installed properly before connecting the modem to your computer.

Belkin F5D77230-4 - connecting to modem


Hi,

It would seem that:
Your modem has only USB output;
Your Router has only Ethernet input with WiFi & 4 LAN port outputs; and
You want your laptop to be access the Internet through wireless connection.

There are USB to Ethernet converter/adapter, an example is shown here.

There are on the otherhand, comparable modems to what you have that provides both a USB and an Ethernet output such as the ProLink H9000 shown here .

Perhaps your best course of action is give your provider first a call and see if you can require them to replace your modem with another model/version, one that has an Ethernet output or a combination.

Alternately, a way can be configured if you have a desktop that has both a USB and Ethernet that we can set up as Gateway (but this is the long method).

Hope this be of some help/idea. Pls post back how things turned up or should you need further information.

Good luck and kind regards.

I'm trying to hookup a usb modem broadband to a router for a desktop and laptop


This wireless router does not have any USB connection on it. Types of connection available on this router are wireless and Ethernet. You can check on the modem if there is an Ethernet port on it.

If your modem has an Ethernet port, I recommend that you test the Ethernet connection using one of your computers. We want to make sure that the Ethernet connection on the modem is enabled. If not, you may need to contact your ISP or the modem manufacturer to make sure that the Ethernet will work before you install the router.

If your modem does not have have an Ethernet port on it. This is not the router that will do the work for you. And I personally does not seen any router yet with the USB port for the modem.

Trouble connecting netgear wireless router to rca modem DCM425


First try connection the Yellow ethernet cable from the rca modem to your computer's network connection. If you get a connection this way, then your modem will work with a ethernet cable. If not, then call Comcast for help. The modem ethernet out to computer port must be connected to the wan line of the router. Then you can connect an ethernet cable from your computer network connection to one of the 4 ports of the router. For wireless connections you must set up the router and wireless adaptor with the same settings to connect. Follow the routers directions.
Good Luck

Connecting modem via ethernet cable


I'm not an expert in window based units but since it worked with Vista OS and not with XP. Sounds like you might try re-installing XP again. Take note on any windows that refer to the ethernet port during installation. It is likely you might of hit "next" without reading all the text. I know I have in the past. I changed over to mac and I know longer have any problems only at work but give then I give it to the IT Dept and wait and wait and wait.

Wireless routers


Just plug the cable modem ethernet into the input to your router and you will be fine. Just remember, if you decide you want to make any changes to your router settings through your browser, make sure you hook up an ethernet line from your laptop to the router before making any changes. The reason for this is if you make a change in security settings on your router while wireless, the router will reboot and if your laptop did have the settings changed in it, you can be locked out.
Not that you can't get back in, but it is a pain to have to do.

Wireless router installation


Please see my response to this question. Your university's connection is most probably a LAN connection, so you'd need to follow the instructions as if you had a cable internet connection (unlike DSL, a LAN connection and cable internet connection don't require authentication with the ISP).
