connecting to internet using windows 7 on a macbook pro with airport express
I have a new macbook pro 15" and I can connect to the internet via my airport express when I'm in the Mac OS X mountain lion operating system but cannot connect to the internet when I'm using the windows 7 operating system. The windows side recognizes that the network is there but won't connect to the internet. How do I fix this problem?
MacBook Pro, OS X Mountain Lion (10.8.2)
