Local Area Connection doesn't have a valid IP configuration

    I've just done a clean install of Win 7 Ultimate 64bit on a Dell Latitude D630 Laptop and all went fine, however, the internet connection (wired) appears to be hit & miss on startup. Some times it connects fine & others it doesn't.

    The device manager is reporting that the NIC is fine and working properly.

    When it doesn't connect it returns the following Msg.

    "Local Area Connection doesn't have a valid IP configuration"

    If I disconnect the cable & re-connect it it sometimes connects but not everytime.........

    Google suggests that it might be Bonjour related but I don't have iTunes or anything really installed other than the OS, MSE & Malwarbytes.

    I'm a tad stumped as to what might be causing this :confused:

    To rule out DHCP being an issue have you tried setting a static IP address? I.e: 192.168.1.56 (for e.g) or something higher up meaning less chance of an IP address conflict.
    Are the LAN drivers up to date?

    Did you install the driver from Dell or was the network card autimatically detected?

    Just tried with static IP but the results are the same, no connection on startup but when I remove the cable & re-connect it works, same as before static IP. Lan drivers are up to date.

    automatically detected Torgay.

    I can only see drivers for wireless NIC on Dell site they have nothing for 7 or Vista for Wired NIC.

    Thanks Torgay, that Diagnostics Utility ran and gave me a green light so it seems to think all is well. The problem is still the same though :confused:

    That was the driver installed, I re-installed it anyway but it made no difference. Appreciate your efforts ;)

    Turning off network discovery made no difference either I'm afraid.



    There seems to be a massive amount of hits for this on Google but none with a definitive solution.

    Thanks to all for their input :)

    And this was working fine with the old installation? Have you tried a different cable?

    That I'm not sure of Torgay as the machine had a curropt OS and wouldn't boot when I got it to sort. I think my friend would have mentioned the network issue had it existed though.

    I didn't try another cable but will

    Wireless is working perfectly.
