Wireless card "Not Receiving response" from router

Hey guys, I'm having a bit of a strange problem with my wireless NIC card and router. Recently I decided to upgrade to wireless N and hoped that everything would go smoothly, this did not seem to be the case.
- To begin, I have two computers - One MacBook Pro and one desktop running windows Vista ultimate.
- My Mac connects to the network fine, with out without security enabled, I can pretty much do anything and it will still connect.
- My PC, on the other hand, refuses to connect to the network at all. There was a point in time where it would only connect if security was disabled, but now even with security disabled I cannot connect.
- I don't have any type of MAC filtering enabled, I've tried all types of security (WEP, WPA, and WPA2), I've tried to manually set my IP address, but no matter what I do I keep getting the same error.
- The error I receive is " Wireless Association failed because Windows did not receive any response from the wireless router or access point "
- I have the latest firmware and drivers, all straight from linksys. I have also reset the route numerous times and I've uninstalled and reinstalled the NIC card more then once.

I would greatly appreciate any input or help that you could provide! I'm seriously at a loss now

 

May be this can Help.
