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 have recently started having this "default gateway not available" issue. A few additional/interesting things:

    • I have been using WIN 7 for over a year on my network without this issue.
    • It started only after I changed my setup from Netgear DGND3300 (modem/router combo) to Netgear SRXN3205 (VPN router) + Motorola/AT&T modem.
    • It ONLY happens when making backups or during large file transfers.

    This sounds very similar to my own situation.  I purchased an apple extreme router and since then, I'm experiencing these issues every 5-15 minutes.   I haven't noticed that it's more prevalent when doing large transfers.  For me, it almost seems to happen on a scheduled basis.

    I have the same problem, only with an Intel wifi driver.  After a lot of failed experiments, I found that it was fixed by uninstalling Bonjour.  Not sure what impact it will have on iTunes and sharing iTunes libraries, but I'll live without iTunes if necessary.
