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.

    Well my Home Media-PC running Windows 7 64 bit uses a Realtek PCIe GBE Family Controller and my Windows 7 32 bit installation inside of Virtualbox on my Laptop has an Intel card, which is virtual but it does use the Intel Pro/1000 MT drivers. Both experience the same issue, intermittent loss of connection. These machines are completely different yet they both do it, different network cards, different architecture (32 bit vs 64 bit) so I'm working on finding what they have in common.  My Media-PC seems to do this when pushing a lot of activity, like transfering large files from the internet and streaming video's off the Internet. Seems heavy activity triggers it. My Virtualbox Windows 7 installation on my laptop (base OS is Ubuntu) seems to do it almost at random for no apparent reason at all. After reading all these posts though it seems it also affects Nvidia cards, so this is more Windows 7 than anything. Some of the solutions here are silly (like setting static DNS, wtf?) but others seem interesting. The 3 I recommend trying then are:

    1. Delaying the Bonjour service startup. (Although my Virtual Windows 7 doesn't have Bonjour installed, my Media-PC did and it doesn't hurt to try this, just in case but doubtful it's 100% of the cause all the time)
    2. Going to device manager, right clicking on your network adapter going to properties and go to advanced and disable the following:

    a. Receive Side Scaling

    and

    b. Task Offload

    Now only one of my two Windows 7's experiencing this issue had one of these options, which was Receive Side Scaling. I haven't found a computer with "Task Offload" but they both have these common 'offload' options  "IPv4 Checksum Offload" "TCP Checksum Offload (IPv4)" and "UDP Checksum Offload (IPv4)".   My Media-PC has additional 'Offload' options like "Large Send Offload (IPv4)" "Large Send Offload v2 (IPv4)" "Large Send Offload v2 (IPv6)" etc. but since I'm looking for a commonality between these two completely different Windows 7 installations and computers, I doubt it's one of these.   I'm going to play with the common options such as "IPv4 Checksum Offload" and the TCP and UDP Checksum Offload's.

    1. Never hurts to disable IPv6, it's not really used by normal people at this point in time anyways, and it also never hurts to uninstall your network adapter in device manager and let windows redetect/reinstall it.

    Is you're PC connected to the modem through a router? I had the same random disconect problems since i installed Windows 7 and the solution for me was a firmware update for the router
