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.

    disable 'Receive Side Scaling' in the nVidia Control panel | (Adjust Ethernet Settings > Configure) | worked for me.

    thanks!

    i have the exact same issue. i've tried various fixes listed here.

    i have the gforce 9300m gs video card.

    these are my two network adapters:

    Intel(R) WiFi Link 5100 AGN

    Realtek PCIe GBE Family Controller

    one thing i noticed is that this doesn't occur when i connect to someone elses router. i live in the dorms and this only happens when im connected to the university's internet. i have the latest drivers for these 3 devices listed here.

    Same problem here with my HP Pavilion a6733nl running Win 7 ultimate 32bit with the Realtek PCIe GBE Family Controller with driver 7.6.820.2009 (latest available from hp)

    Problem first was seen after the upgrade from vista to w7

    Reading all the issues it looks to me like an MS problem...

    Ok...I think I have solved this. I was having this problem with my Lenovo T400s running Windows 7 [with 5100 AGN card] connecting to my Belkin N+ wireless router. I kept getting disco's everytime there was a change on the network [laptop restart, modem restart, etc] and would have to keep restarting.  I had windows xp before and this didnt happen.

    Now I cant say which step actually solved this issue but here's what I did, in this order:

    1.  Updated firmware on Belkin N+ router [the update facilty on the admin page showed that it didnt need updating but when I went to the Belkin website i found the latest firmware and it updated fine]

    2.  Updated my wireless card in laptop with latest drivers.

    3.  Updated the GigE network card with latest drivers.

    4.  [this is the step that I think made most difference but not entirely sure] I set my router and wireless card to 'bond' the wireless channels, so that instead of using just one channel [upto 144Mbits/s] it will use 2 channels for a combined throughput of upto 300Mbits/s.  You can obviously only do this if you have both an 'n' spec router and an 'n' spec wireless card.  google 'wireless channel bonding' for more info.

    Hope this helps.. :0)
