    Windows 7 Network Problems

    I'm not sure if anyone here is able to help - I'm starting to pull my hair out trying to find a solution.

    The problem that I am having is that everytime I start (or restart) Windows 7 (Pro), I lose my network connection. But the thing is that if I disable and re-enable the network card the network then starts to work as intended.

    I have tried a minimal startup, and disabling various services in order to see if there is something during startup that is causing the problem, but so far to no avail!

    Has anyone else come across this problem?

    The network card in question is a nForce 4 network card on my motherboard.

    PS. Even a batch script of some sort just to disable and re-enable the adaptor would be a help at this point.

    Re: Windows 7 Network Problems

    Is it the actual connection that is not working or is it simply not getting an IP?

    eg is it saying disconnected ot just saying no connection?

    to disable a network card the best way is to make a script using devcon

    http://support.microsoft.com/kb/311272

    eg

    REM NetworkRestart.cmd
    @echo off
    ping -n 1 www.google.co.uk
    if %errorlevel% EQU 0 goto end
    devcon restart PCI\VEN_14E4
    :end

    Replace "PCI\VEN_14E4" with the correct ID

    If its just needing to be repaired every time then thats a simple one

    REM NetworkFix.cmd
    @echo off
    ping -n 1 www.google.co.uk
    if %errorlevel% EQU 0 goto end
    ipconfig /renew
    :end

    Other things to try is disable IPv6 and get the latest drivers

    Re: Windows 7 Network Problems

    Do you have anything to do with the Bonjour service on your PC?

    If there is anything Apple / Adobe it causes a multiple known / unknown network issue!

    There is a tool called turnoffbonjour which you can download here.

    Hope this helps!

    Re: Windows 7 Network Problems

    I do have bonjour service and have seen posts relating to it, but turning it off makes absolutely no difference.

    What happens is that if you do ipconfig /all it just shows a network connection #9, but it is not linked to any kind of IP, so trying ipconfig /renew or /release does nothing as their is no adaptor.

    I'll try that network card script

    Turning it off doesn't make a difference! Removing it does!

    Not yet - I have an old PCI card kicking about somewhere, so will be trying that when I get the chance

    Re: Windows 7 Network Problems

    Bit of a strange one this. Weird how it is showing as the network card/ connection not been installed. Maybe download the network device drivers, uninstall the card/ drivers and then re-install, see if it is a driver issue?

    Re: Windows 7 Network Problems

    The trouble is that it is a nforce4 motherboard, so no proper Win 7 drivers. The one windows installs works fine, except for at startup

    I've even tried setting everything up without DHCP too, but to no avail.

    It is as if on every restart windows deletes the working connection and tries to recreate it, but fails. Yet once the card is disabled and re-enabled it the strangely works

    Re: Windows 7 Network Problems

    Well the spare card I have appears to be a bit too old for windows 7 drivers (built in), mind you it does have a BNC connector on it as well

    So for now I have setup a task to run on logon (as devcon requires admin privilages), so for anyone else who may be having this problem, this is the script I am using:

    Code:
    @echo off
    
    ping -n 1 www.google.co.uk
    if %errorlevel% EQU 0 goto end
    c:\dos\devcon disable =NET @PCI\VEN_10DE*
    c:\dos\devcon enable =NET @PCI\VEN_10DE*
    :end

    Re: Windows 7 Network Problems

    What card do you already have?

    It's not Realtek is it?

    Re: Windows 7 Network Problems

    I've had problems too with Network dropping out for no reason, Seems to have been a driver issue.

    Now using a later driver from Marvell Yukon, Seems OK at the moment.
