First thing is first... you should always be able to have access to your router.
On the back of the router will be a RESET button.
You might need a bobby pin/paperclip... hold it in for up to 30 seconds. or until the lights on the front start to indicate that it has been reset.
to get into a belkin router.. this is the ip address: http://192.168.2.1
Pass: *ships with no password*
I had a belkin and i looked up your router and that is what it wil be after the reset. I would definitly hard wire into your router until we can fully cofigure it correctly.
If you would like helop, i'll be more than happy to remote desktop with you

Here is the Firmware as well. This could help you get your router working with Windows 7 a little bit better. I am not sure of your version nor of the version on this page.... So, its a shot in the dark.... but it does have instructions on how to do it. http://en-us-support.belkin.com/app/...etail/a_id/299
