    Network Connection Fails to Connect on Start up Randomly


    Hello;

    This has been happening for the better part of 10 months now. Its happened on both Windows 7 and Windows 8 (8.1 to be specific).

    I cold boot the PC and sometimes the network connection will not connect. There are two ways to solve this:
    1) Reboot works everytime I believe
    2) Or just open the PROWinx64 zip (Intel Network Connections Install Wizard)

    This is the interesting bit - I don't reinstall the driver, I merely open the zip, it extracts and it loads the very first screen of the install wizard. That's all that is needed to connect the network.

    This began happening after I resinstalled Windows 7 last year, and after a bit of searching for a solution I decided to just upgrade to Windows 8.1 However, as I've seen the problem still persists.

    Is this indicative of a hardware failure or what might be the issue?

    I have tried multiple drivers. The latest one listed on the ASUS page (P8Z68-V Pro mobo) is from Sept 2013, so I've also tried one from Intel's page

    Welcome to the Forums.

    Are you talking about mapped network drives that are set in Explorer to automatically reconnect?
    If so you could try the net use command instead, in a batch file after a delay. The NIC may not be ready when the system tries to remap the drive on a cold boot.

    But I won't go into more detail until you reply since you may be referring to another issue.

    Hello, Thanks!

    This is the Ethernet driver that fails to connect. So the Network Internet Access.

    Somedays I cold boot (today) and no issue, other days little red X on the network icon and no internet connection. It will stay like that until I either reboot or unzip the network driver package. I don't even need to install, just the unzip and install prep gets rid of the hiccup.

    Ok. I see what you are saying now. It sounds like some intermittent hardware issue. I would be surprised if it is not temperature dependent. It sounds like once it has a chance to hit a certain temperature it will take the initialization.

    If fixing the hardware is not desirable a work-around may be to hibernate or sleep but with the NIC remaining powered.

    Edit: There's no guarantee that it will stay the way it is for a long time. But otoh it may not be that inconvenient to leave the card powered and it may work for quite awhile.

    I had a NIC with the opposite problem. Ran great from a cold boot for about 45 minutes. Once warm it locked up. Warm boots only got function back for 5 to 10 minutes until another lockup. I replaced the card and all was well.

    I've done a bit of testing and temperature doesn't seem to be an issue. From a cold boot I've begun taking a hairdryer to the intake fan for a few seconds before booting to increase the temperature in the case before booting up. No difference. I've done 7 cold boots and 3 with the hair dryer and it's failed to initialize the network connection 4 times - once with the hairdryer.

    Right. But a bit higher ambient temp in the case is not the same as temp on the chip. I don't know what normal operating temp is on network chips. But a few seconds of current likely brings them up quite a bit. Perhaps a hw aficionado can contribute to the discussion?

    edit:

    I know in debug class the instructor mentioned detecting chips that failed when hot by spraying refrigerant directly on the chip and all of a sudden function returned. But I'm no hw expert. I;m not sure about the other scenario, fails when cold.

    Edit2: Maybe a hw expert could answer this. On first cold boot would it make any difference if the machine was brought up to some settings page and allowed to sit? I don't know exactly when the NIC would get current. Maybe not until initialized by the Windows driver? I'm just wondering if letting the machine sit for a few minutes before login would be another way to test?

    Lets back the train up quite a bit here. If you have installed the proper Ethernet driver and using a good Ethernet cable between the computer and the router, then you should be getting a connection. If not, then most likely the Network chipset is toast.

    You do not need the Intel Proset tools for the Ethernet Chipset to work.

    There have been no issues whatsoever with the ethernet once the driver is working properly. The issue is *only* at startup. If I had a bad cable or chip wouldn't I see at least some other issues?

    You would have to test the cable first, to make sure it is not bad. As for the chipset, it will either work or not work. I have seen where they will work on a cold boot. But after the unit warms up a bit, you lose connection. That is when you install a PCI or PCIe NIC, due to the onboard chipset has failed.

    I don't see mentioned anywhere if the NIC is set to allow power off to save energy? I've seen this type of problem go away when the NIC is set to always on, even when the machine is shut down. In fact my HP desktop was having funky network access issues until I changed it to always on. Even when shut down you should see the green LED at least for a card. I'm not sure about chips on the motherboard.
