Well if its a secured connection, you definately need a key to access it. However, if its unsecured, you should be able to connect with no issues. You may have to delete your existing wireless connection settings and reset them up.
go into the network and sharing center and on the left, you should see where it says manage wireless connections. Go in there and you should see your home wireless connection and others. I would delete all but your home connection and try connecting again.
