I've just updated to Windows 7 and I'm having a rather odd problem.
I have a Netgear DG834N router that is being used by several computers in the house with no problems. As soon as I boot up my Windows 7 machine the bandwidth seems to drop and the internet becomes unusable on all computers. This happens when starting Windows 7 without even opening any programs that connect to the internet.
I have read of an error reporting issue that caused this in the early beta release but I can't find any evidence that this is what is happening on my full copy.
Does anyone have any ideas on how to fix this? I've not been able to find a solution here or anywhere else.

If it helps here is my ipconfig:
