WPA has its own weakness too, but it is harder to crack. WPA2 is highly recommended for SME or enterprise; remember than anything man made can be unmade. 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.

      My daughter got serial numbers, phone serial numbers, IMEI number from our phones. She has her own illegal internet, uses our wifi, our data, how can I find it? The phone companies don’t want to chase it. She got my personal information and got credit cards, loans in my name. I reported that, but it’s so hard to prove. She changes ip address
