default gateway not available in windows 7

G'day,

While Windows 7 works and looks good, there is one major issue which threatens to derail the entire experience for me.

Several times a day, the default gateway becomes unavailable, which means that the PC running Windows 7 loses internet connectivity. At the same time, other PCs, running Vista, are continuing to work normally. This includes one PC with a WiFi connection and another which is normally wired.

The details of my network controllers (there are two) are as follows.

Description . . . . . . . . . . : NVIDIA nForce Networking Controller

   Manufacturer  . . . . . . . . . : NVIDIA

   Provider  . . . . . . . . . . . : Microsoft

   Version   . . . . . . . . . . . : 1.0.1.211

   Inf File Name . . . . . . . . . : C:\Windows\INF\netnvm32.inf

   Inf File Date . . . . . . . . . : Wednesday, April 22, 2009  12:47:44 AM

   Section Name  . . . . . . . . . : NVENET55.NDI

   Hardware ID . . . . . . . . . . : pci\ven_10de&dev_0373

   Instance Status Flags . . . . . : 0x180200a

   Device Manager Status Code  . . : 0

   IfType  . . . . . . . . . . . . : 6

   Physical Media Type . . . . . . : 14

The problem is solved by manually having to repair the problem when Windows 7 finds that the default gateway is not avaialble and resets network controller 2.

I have seen that this is not an isolated  with several reports on the net, some suggesting that a different driver might help, but which one? Any suggestions?

It's one of many known nVidia issues with Windows 7 that nVidia must correct, unfortuniately Microsoft has nothing to do with it. I would sugguest that you contact nVidia for assistance.

    I doubt that there were NO drivers installed for the dual Nvidia network devices. Windows 7 would have installed it's defaults.

    More than likely they got disabled somehow.

    You need to go to Nvidia's website and download the new Nforce WINDOWS 7 .inf files (NOT vista) for your particular MB if it has an Nvidia chip.

    But, that is probably not the solution to everyones problem here, anyway.

    I addressed this solution in another post, but here it is again:

    This is NOT a driver issue or a TCP/IP configuration issue...although it's a good idea to make sure you are using the latest chipset drivers from your  manufacturer.Go to Control panel ... then administrative options.Then "services".Scroll down and find a service named "Bonjour service". double click on this service, then disable it. Now choose "automatic (delated start)".Click OK then close everything and reboot, when you do, your network and internet connection should be fine.Takes a lot to explain the problem but it is a service created by Apple that is commonly used in several applications to get your network card to configure itselfautomatically to work with certain services. It does not play well with windows services as a rule, and delaying the auto start gives the windows services time to start prior to its activation at reboot.Hope this helps!

    Found the solution.  It was driving me nuts too and didnt want to reinstall windows.

    You have to install the nforce vista drivers for the windows 7.

    Right click on My Computer and select Manage

    Click on Device Manager in the left hand pane

    Expand Network Adapters

    Right click on the first network card and select Update Driver

    Select the 2nd option which says something like "Browse my computer"

    Then select the 2nd option in the window that pops up that says "Let me pick from a list of device drivers"

    Click the "Have Disk" button

    Browse to the folder where you have the drivers extracted and the 15.25 drivers should show up.

    Follow along and they'll be installed. I think you'll have to do it for the 2nd card if u have one but I'm not sure.

    Folder should be called something like C:\NVIDIA\nForceWinVista64Int\15.25[Ethernet](http://www.sevenforums.com/#)

    In terms of the drivers, Just get them from nvidia's website or search google for nforce 15.25 ethernet. Hope this helps.

    So that I can better understand your problem...

    Does your connectivivity just fail with no warnings, or do you get an "unknown network" that shows up in the network and sharing center when this happenss?
