Belkin N-1 Wireless Cards and Connectivity Issues

I have been reading alot of the connectivity issue with all different
cards. I am currently having the problem with a Sony Vaio and a Dell
Inspirion and 2 Belkin N-1 Wireless Networking card. My cards worked
for a while and then they stopped and have not been able to get them
back working. I have tried many combinations of things. Windows will
say it is connected (when in fact it is not) and Belkin will say it is
not connected. I have two Dell Desktops that I do not have this
problem at all.

1) Turning Wireless Zero Configuation off, on disabled
2) Using Windows for the wireless connection only
3) Using the Belkin Network Utility only
4) Re-booting with Belkin Network Utililty off and using only windows
5) Putting the Dword Value in WSCZC to 2

It seems that until I can get a green antenna in my sys tray the
connection is not complete. I suspect that the card is sending but not
receiving.

Anymore suggestions out there????
