    Unidentified Network


    I can't get the wired Ethernet Local Area Connection to connect.

    I have been trying fixes for hours. Nothing seems to work.

    I have just installed Win7 Professional. I have installed all Win7 updates except IE9.
    I have updated all drivers with Lenovo system update.
    I can connect wireless.
    I can connect other PC's to my router.
    My router (Sonicwall) company thinks it's a laptop issue.
    The troubleshooter can't find the problem.
    There are no red x's or yellow exclamation points in device manager.

    Can someone please try to help?

    Thanks,

    Bypass your router, take it out of the equation.

    Connect directly to your modem via e-cable. ensure you do NOT have static ips for ANY address, even dns/dhcp.

    You may want to shut down your computer and power cycle your modem before connecting.

    I have removed the IP addressing, I have shut down the computer and the modem.
    I have turned on the modem and let it connect back up. After that I have turned on the computer. I still have Unidentified network.

    If you were plugged into the modem on that ipconfig, your modem is not proving an IP address (unless you manually removed the gateway)

    Yes I did.

    I don't think the Ethernet is working even though the drivers are installed correctly.

    is this an onboard ethernet adapter? When you have a cable plugged into it, can you see a light on the adapter?

    Yes. It's a laptop. Lenovo T510
    There is a blinking orange light b4 I plug in the cable.
    After I plug in the cable there is no light.

    I have tried a different cable. Same results.
    I have tried plugging the same cable into a different laptop. It works fine.

    Hello,

    See if resetting the TCP/IP and Winsock helps.
    Click on Start=> All Programs => Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.
    Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log press enter
    Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log press enter
    Reset WINSOCK entries to installation defaults: netsh winsock reset catalog press enter

    Restart the computer after and test your connection after.
    Please let us know.

    ===============
    If above recommendation didn't help perhaps a new network adapter might be needed.
