Just be aware, WPA with a weak passphrase is easier to crack than WEP.

to crack WEP, an attacker has to gather many packets, possibly millions, but 
can then easily crack any key. For WPA, certain shorter or dictionary-based 
keys are highly crackable because an attacker can monitor a short transaction 
or force that transaction to occur and then perform the crack far away from 
the physical site.

Pick passphrases that aren’t entirely comprised of dictionary words, meaning 
they need some random nonsense in them. “My dog has fleas”: very bad. 
“Mdasf;lkjadfklja;dfja;dfja;d”: very good, but hard to type in. Passphrases 
should be at least 20 characters.

A random passphrase of at least 96 bits and preferably 128 bits will defeat 
the cracking
