    I just got my internet hooked up in my new apartment yesterday, and it is not working when plugged directly into my laptop. It worked fine on the installer's laptop, though.
    A buddy of mine let me borrow his wireless router and the wireless works fine with that, although if I try to connect wired through it, that does not work either.

    It says I'm connected to an unidentified public network and I get the above error when I try to connect. I've tried disabling IPv6, restarting both the modem and my laptop, and updating the ethernet driver, which I could not find (HP dv2715nr is my model and I have windows 7 ultimate).

    Below is my ipconfig with the modem plugged in and the wireless turned off. Hope this is enough info and thanks for any help!

    Have you tried a different ethernet cable? I am assuming you are using a known good CAT5 cable.

    I did actually try another ethernet cable, which also didn't work. Both work going between the modem and the router. This one is really baffling me.

    Another bit of information: the last time I can remember the wired port working was about a year ago, and no new major upgrades have been done, besides the usual program updates and windows update.

    Some things you can try. Won't hurt and may help.

    TCP/IP stack repair options for use with Vista or Windows 7.

    Start, All Programs\Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.
    or Start, type cmd in the search box and right click on cmd.exe, select "Run as Administrator" to open a command prompt.


    In the command prompt window that opens, type type the following commands, each followed by the Enter key:

    Reset WINSOCK entries to installation defaults: netsh winsock reset catalog
    Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log
    Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log
    Reboot the machine.

    others would be,

    ipconfig /release
    ipconfig /renew

    Not sure how to change an Unidentified Network from public to private.

    Tried the resets as well as the suggested driver from HP. Neither worked.

    Below is the output from the ipconfig release and renew. Got an error during each. Note: I did this while plugged in directly to the modem and connected to the router, which was not connected to the modem. It would give me an error if either the wireless was turned off or the ethernet cable was not plugged in.
