Varying on your Network Adapter/Driver, you may have to allow your TCP/IP & DNS to set automatically, rather than manually. If anything, the easiest way to check for issues is to right click on your "Network" Icon in your System Tray, and click "Troubleshoot Problems".

Manual Steps:

  1. Rick Click the Network Icon in your System Tray.
  2. Left Click "Open Network and Sharing Center".
  3. In the Left window pane, click "Change Adapter Settings".
  4. Right Click "Local Area Connection"
  5. Left Click on "Properties" (and Allow the UAC)
  6. Click on "Internet Protocol Version 6".
  7. Click the "Properties" button.
  8. Make sure the "Obtain {yada-yada} automatically" radio-box is selected on both the IP and the DNS.
  9. Click OK.
  10. Do the same for "Internet Protocol Version 4".
  11. Restart your Computer

If the Issue still exists after these steps, verify that your Router or Modem is compatible with Windows 7.

Not all routers will work correctly with a Windows 7 based System.

Hope all is well.

I had the same problem. Try this:
1. Open "Device Manager"
2. Disable your Network Adapter
3. Wait a few seconds and re-enable the Network Adapter

Tried that aswell, still no internet, didn't restart between the disable tough.

getting verry annoying that it works on every single computer in my house BUT not my windows 7 machines.

i maybe should mention that i got the lastest firmware on all my routers but it doesn't made any diffrence

and like i mentioned later it all started this morning, everything worked like a good flower yesterday. i also have called my internet provider and they tell me that there shouldn't be any operating errors for now.

Don't bump so soon. Someone will get to you.

Anyway. I'm guessing windows probably updated your ethernet drivers on your windows 7 box. Uninstall your network adapter and re-install it using these drivers.

Using dual routers will cause problems because of having two internet gateways. There should only be one router on your network if you want to work correctly. Sometimes you can bypass the WAN connection on one of the routers and use it as a switch but that configuration is usually not supported.

So the only way for me to get my net working on my win7 machines is to remove one router? i got two since i got over 6 computers that needs internet. and my first router only supports 4. so thats why i got 2.

but its odd for me that it worked before and just suddenly stopped working this morning..

Yes it won't be very reliable that way. You should be using a switch there instead of a router or if you need to have wireless and wired you can use a wireless access point or use a router that supports both.

There are also ways to use the router as a switch by bypassing the WAN connection but that configuration isn't officially supported by D-link. You can google the set up procedure for that but it's much easier to just use a switch.
