    Network Cable Unplugged error: cable is plugged in


    Hello,

    Since last night, my LAN connection has been giving me the error "Network cable unplugged." I have tried swapping the cable with another, swapping the ports on the router, restarting the router, power cycling the router, turning off the router and my computer and then turning them back on, and nothing has worked.

    My computer has two network connections: Realtek PCIe GBE Family Controller and a Hamachi network, which the computer is using (but not getting Internet on, of course) - I assume because it isn't giving a network cable unplugged error. This is the network controller that comes on my Gigabyte MA790X-UD4P motherboard, and it has the latest driver from the manufacturer's site (7.6.820.2009). In the device manager, it says that the device is working properly. There is a green light under the ethernet cable on the router, but not where it attaches to the motherboard (I can't remember if there was one before or not, though).

    The Realtek Diagnostics Tool says the following:
    IP Address 0.0.0.0
    Connection NAme: Local Area Network
    Link Status: Disconnected

    It has a tab for Cable diagnostics, which says the following (Pair/Length/Status):

    1-2 0 Normal
    3-6 115 Normal
    4-5 0 Normal
    7-8 191 Short

    When I run diagnostics, Register, Mac Loopback, PHY Loopback, IRQ, and FIFO all pass.

    Here is what ipconfig/all says:

    Primary Dns Suffix . . . . :
    Node type . . . . .: Broadcast
    IP Routing Enabled . . . . : No
    WINS Proxy Enabled . . . . . : No

    Ethernet adapter Local Area Connection:
    Media State . . . . . : Media disconnected
    Connection-specific DNS Suffix . . . . .:
    Description . . . . .: Realtek PCIe GBE Family Controller
    Physical Address . . . . . : 00-24-1d-1d-eb-b6
    DHCP yes, Autoconfig Yes

    Then it has the Hamachi connection, a Tunnel adapter isatap.{numbers}, another Tunnel adapter isatap.{different numbers}, Tunnel Adapter LAN *9. and Tunnel adapter 6T04 Adapter.

    I've tried plugging the ethernet cable into another computer instead of the router to see if it detects an Unknown Network, but it still says unplugged.

    Running the Windows 7 Diagnostics asks me if it's plugged in, I click next step, and that's all it offers.

    It was working yesterday. It might have updated. If not, the only thing I can think of that changed on our network (which admittedly consists of a lot of things at the moment: two smart phones, a macbook, two laptops, three desktops - one of them being the one having the problem - a Nintendo DS, and two Wiis) is that we just hooked up one of the Wiis to Nintendo's WiFi Center yesterday for the first time.

    On the router's home page, it views my computer's status as "offline." I checked its dedicated IP and made sure none of the others overlapped, and they don't. The computer in question cannot access the router, which is a 2wire Gateway.

    Oof, any ideas?

    Have you tried a different network cable? Your diags here say you have a short on 7-8.

    Yes, I've tried three. They all work on the computers they're normally plugged in to, but not on the problem one. That cable reading was on the one that is usually plugged in to it.

    hi, i have the same problem, except for the cable and for the diagnostic test (mac loopback and so on), that, after i've updated the card to the last driver, it fails all tests except the register one. With old drivers it fails only mac loopback test. Also the green light on the motherboard is off while the yellow light is on sometimes. Hope someone can help me. Sorry for my bad english :)

    EDIT: now with the last drivers the tests are ok except for the mac loopback... any ideas? Oh, i do the tests one by one, not all in the same time

    P.S
    That happened after i installed the last version of ubuntu x64 with the command "install in windows"
