    i have a USB/Ethernet modem, but i can't seem to get the modem to work with ethernet. it works fine with usb so i use that. i hear Ethernet is better and i want to take advantage of it, so i hooked the ethernet cable up, but it doesn't recognize the connection. can anyone help me? :(

    i have an RCA modem, and the lights are on when i plug it in, but the little icon in the taskbar says, the cable is unplugged, so i moved it around until the icon went away but it still didn't connect. i think somthing could be wrong with the cable or my NIC card, which was built into the mobo. i use Windows XP and i'm not sure if it's a crossover or straight through. i'm kinda new to broadband. it goes directly from my modem to my computer if that's what you mean.

    What are the lights on that modem doing when you have it hooked up via ethernet?

    I say first check out the NIC, make sure it's working correctly. So, does windows say that the ethernet card is installed in the device manager? It doesn't have a red X or an exclamation mark next to it right?

    If it checks out ok there, go to start --> run
    type in command, hit ok

    you should be in a dos box
    type "route print" without the quotes
    you should see 6 or 7 lines under the column headings such as Network Destination and Netmask. If you only see 2 lines, it could be 3 things. The drivers aren't installed correctly, the NIC is disabled in device manager, or the Local Area Connection under your network connections control panel is disabled.

    Check those things and let me know.

    Also, here's how to identify a crossover cable.

    It's important because some modems use a straight through while others use a crossover between the modem and computer.

    Assuming your nic and cable are good.

    go to start --> run
    type in command, hit ok

    you should be in a dos box
    type "netsh int ip reset c:\resetlog.txt"
    that will reset TCP/IP to a clean state
    and then reboot

    then go to the dos prompt, same way as before
    and type "ipconfig"
    and plz paste the information here
