Of course, but causes more connection problems than anything.
If you are a home user, then the chances of someone doing some wardriving and ACTUALLY being good at it, are slim to none. And unless you have VERY VERY sensitive information, then there's no need for turning off SSID visibility. Again, it's ONLY causing you problems with connectivity.
WPA2 is strong enough, and most devices these days can utilize it. And if you want to secure your network, and keep people from accessing it, your shares on your network should have user accounts to allow access to only certain people. Force AES if your devices are capable of it too.
