both WPA and WEP also easily hacked...I've attending wireless hacking course.

anyway,
1. hide your access point may reduce the risk of being expose to public.
2. also, turn off your router while you are not using.
3. downloading using p2p software may make your access point more vulnurable.
4. limit the access for your access point.(MAC or IP filtering, ACL)

This is the prevention you can do.

haha, you're right
perhaps most secure way is don't use wireless access

*is there any features for your router to make your access point hidden?
it will become invisible in windows platform, that should prevent some hackers from detect your access point during wardriving.
