This gives hackers more time to crack the encryption.
Advantages of WPA over WEP are:
Length of IV (initialization vector) is now 48, comparing to WEP’s 24. This gives you over 500 trillion possible key combinations.
IV has much better protection with better encryption methods. This is prevention of reuse of IV keys.
Master keys are never directly used. Better key management. Impressive message integrity checking.
