Can it be hooked up to internet via usb port

Can what be hooked up via USB? You have a picture of what appears to be a speed stream 4100 modem there but there is not enough detail to your question. If this is the 4100 Speed Stream modem then no you do not connect it via USB as it is an Ethernet based modem Can you clarify what it is that you are trying to do please.

Have system for voip. Only can't hook up the

Try getting a router that has one in/4 out between modem n voip. Your voip unit should have an RJ45 connector to connect to router, not your computer. The USB connector might be to connect the voip to a different type of router, and will not be used. The 2 phone connectors are for two different phone lines that your voip provider can provide you with.

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

Toshiba Cable Modem PCX1100u

OK. First of all you do not need a special or seperate driver for the Ethernet port. Its factory loaded with your OS.

All you need to do is plug the Ethernet cable into the LAN port on your HP Desktop and then into the LAN port (not the WAN port) of your cable modem.

The second thing is if its only a cable modem, then I suggest you proceed with caution as there is NO built-in firewall on a cable modem. Yes you will get on the net, but you are likely to be attacked with virus the moment you connect. I suggest you check very carefully whether the cable modem (if that's what it is) does/does not have a firewall as you would be very unwise connecting up like that.

Next, forget USB connection to the router/cable modem. That technolgy we've moved on from.. Your Vista shodul be 'plug n play' adn should configure the router for you. obviously that bit isn't so slick on yours.

Let me know how you get on..

If the modem is already registered to your ISP then you can plug the modem to your computer using an Ethernet cable (CAT5) to your computer's ethernet port and to the modem's port as well.

If you want to use the USB cable then you need to install the drivers for it. You may go to motorola website and type in the model number of your modem to get and download the drivers.

Though, I suggest that you use the Ethernet connection instead.

Need to hook up Belkin G wireless router to Motorola SB5120

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.
