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?
Locked Question. This question was migrated from the Microsoft Support Community. You can vote on whether it's helpful, but you can't add comments or replies or follow the question.
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 was having problems with losing my default gateway setting every time I rebooted, resulting in the same issues seen in this thread; noteably that I could get around the LAN, but the WAN (internet) was blocked. I'd have to go into my network config and add the default gateway every time I booted up in order to get to the internet.
MY FIX - which seems to have solved my problem
Open a cmd window as Administrator
type route -f (flushes all gateway entries from the routing table)
type route -p -4 add 0.0.0.0 mask 0.0.0.0 gateway_addr (where gateway_addr is the address of the LAN port on your router)
exit the cmd window and reboot. My system now seems to run correctly.
I suspect there is an error in the way the GUI writes the default gateway into the registry in Win7

Here's a point of view I read once somewhere in a website. Drivers are provided by the manufacturers of the computer hardware. If a new OS is to be released, they will be the ones that would release the latest driver firmware upgrade (firmware, in short, is a program for the chipset controlling the hardware). Now, Microsoft is a big Software company, firmwares are not therefore released by them since it is a software. Working in a manufacturing company made me see that the firmware is tested even before the release of an OS. That means that manufacturers of the hardware get the OS when it is available, be it Release Candidates or Beta versions. Now, manufacturers would just have an ideal coverage on what will happen because their environment just "tries" to imitate a non-ideal environment where anything could happen. Now the resolution, if themanufacturers are still not releasing the updated driver, would be coming from the computer manufacturer or the manufacturers themselves. Microsoft would be the ones working with the programmers of the firmware (maybe the RnD department of the manufacturers) to give them what the sofware does and how it functions depending on the computer hardware being produced.
After hours of browsing it a shame that Microsoft blamed everyone else when they could have just give the simple advice below.
In the network adapter just disable the Task offload:

Voila!
