    Hey guys, I'm having a bit of internet trouble.

    Ever since moving back in with my dad, I haven't been able to connect directly to the modem. I can connect to the wireless network, but whenever I try and plug straight into the modem, nothing changes and I stay on the wireless. I cannot, for the life of me, figure out what to do (as I'm not entirely tech savvy). I'm running Windows 7, if that helps in any way to determine the cause.

    My computer specs are as follows (directly from the TSG SysInfo application):

    OS Version: Microsoft Windows 7 Ultimate, Service Pack 1, 64 bit
    Processor: Intel(R) Core(TM) i5 CPU M 480 @ 2.67GHz, Intel64 Family 6 Model 37 Stepping 5
    Processor Count: 4
    RAM: 3766 Mb
    Graphics Card: Intel(R) HD Graphics, 1755 Mb
    Hard Drives: C: Total - 476837 MB, Free - 162910 MB;
    Motherboard: Acer, Aspire 5742G
    Antivirus: avast! Antivirus, Updated and Enabled



    I appreciate any and all help with this problem, and will be glad to give whatever information is deemed necessary.

    Thanks,
    Josh

    Are you sure that the cable works?

    You may need to download and install the latest driver for your network adapter from the manufacturer website.

    I have confirmed that the cable does work. My dad uses it with his laptop.

    As far as installing the correct driver, how would I go about it and how would I know which is the right one? Forgive me for not knowing too much about this.

    It's probably not the modem or the cable. Most likely, it's the hardware address.

    When your dad plugged his computer into the modem, the modem (and most likely, the ISP) got the MAC off of his computer. Plug yours in (with a different MAC), and you lose the connection. Most people never encounter this because they never run a modem alone; they also use a router. This not only gives you the ability to use multiple devices, but also provides additional protection from the Internet. You should never use a modem alone, even if you only have one computer.

    Incidentally, Windows 7 (XP and Vista) will always use the wireless connection (regardless of speed) over a wired one, even if both are working. If you want Windows to use the wired connection, you will need to disable the wireless. This should be just a keystroke if you have a laptop.

    Sorry, I think that you have that backwards. At least for XP. I remember one thread years ago in which even a (wired) 56 Kbps dial up was used in preference to a 'G' wireless connection.

    If you are connecting to a modem only you need to at least power cycle the modem when switching the device connected to it. And, as Courtneyc indicated, you can also have MAC Address issues if the ISP is tracking it.

    Start, Run, CMD, OK to open a command prompt:
    (For Vista or 7 type CMD in the Search box after Start)

    Type the following command:

    IPCONFIG /ALL

    [Note that there is no space between the slash and ALL.]

    Right click in the command window and choose Select All, then hit Enter.
    Paste the results in a message here.

    If necessary use a text file and removable media to copy the results to a computer with internet access.
