Wireless connectivity help. was connecting to old router now not to ne

I have a 64-bit windows 7, i just updated my wireless card in my computer, and trying to connect to a netgear wireless router. I am able to see the router but i cant on. It says connecting.... limited access... then it disconnects. Other people were able to connect right away at my firm, but i can not. Please help

all of that does match other computers that are currently connected to the internet

You say you updated your wireless card.. would that be the driver, or did you purchase and install a new physical card?
If it's a new card, try updating the drivers. If it's an old card with updated drivers, try rolling them back tot he previous ones that worked.
