WPA has its own weakness to, but it is harder to crack. WPA2 is highly recommended for SME or enterprise; remember than anything man made can be un-made. WPA2 is crackable too, but it will require too much effort and time. It is easier for the hacker to look for someone using WEP instead of wasting time breaking the WPA2 security code. Below is a simple side by side comparison between WEP, WPA and WPA2.
