Vista - Multiple network connection problems

I'm running the Vista 32bit on my Sony vaio laptop. I was able to connect to the internet thru wifi fine until recently and I'm not sure what happened. Now whenever I go to "connect to" to select a network, it selects the network just fine but that network shows up in my Network and Sharing Center as 2 totally seperate networks. When I try to gain online acess this causes an issue because after running the diagnostic tests I get a command to disable one of the active network connections. So when I try to do this on one connection it takes away both because they are the same. If anyone can give a little insight on this please let me know.
