Try connecting it though the usb and installing the usb driver came on a cd with the modem.
Or connect to the ethernet and install its driver from the motherboard cd

The Cable modem must be disconnected from the computer. You cannot use USB and Ethernet at the same time.

1. Turn off power to the Cable Modem and the Netgear Router. Do the same with the computer.
2. Connect an ethernet cable from the modem to the router's WAN (Internet) port.
3. Connect another ethernet cable from one of the remaining 4 LAN ports on the router to the computer's ethernet port.

4. Now power on the Cable Modem ONLY. Wait for the modem to sync up with your service provider
5. After about 2-5 minutes power up the router and wait about 1-2 minutes.
6. Now power on your PC.

Check and see if you have internet access. If not you may have to uninstall any cable modem software related to USB connection. if this is the case, then you may have to repeat steps 4-6.

Since most cable internet providers do not use proprietary connection settings, your internet connection should be up and running without changing any settings in the router or modem.

If this does not resolve your issues, we can continue to work with you.

Cant connect to xbox live need an ip address how do i get one


When the SurfBoard modem is powered up and connects to the internet on the WAN interface, it automatically gets an IP address from your ISP. When another machine is powered up and is connected to the modem via a USB cable, it is automatically using the WAN IP address to communicate with the world. If it is connected via the Ethernet connection, the modem automatically issues it its own IP address for use on the internal network via DHCP. The modem's internal Ethernet connection is 192.168.0.1. The next machine powered on will normally get an IP address of 192.168.0.2.

No internet connection by using the ethernet cable


Unplug the power to the modem and the USB cable. Plug in Ethernet cable in computer and plug in the modem. Wait for WAN side of the modem to connect and stabilize. If your PC is already on, you should see the network connection appear in the task bar (if it's configured to show up). Open a command prompt. Type 'ping 192.168.1.1' and press Enter. You should get 4 ping responses from the modem which indicates that you LAN connection to the modem is functional.

Let me know if this doesn't work and I'll guide you through other methods to get it working.

Inability to connect to Internet


The easiest solution would be to use an ethernet connection. A second problem is probably on most cable modems you can either use a USB connection OR an ethernet connection you cannoot use both at the same time.

Install


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.

Ethernet Card


Do a ipconfig at the command prompt and see if you are being assigned a ip from the modem. If not try rebooting the modem with the ethernet connected to modem and computer. then do ipconfig again to see if not getting internet ip, your card or modem eternet is bad. put in a new one and try again.

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.
