SUMMARY:
WPA-PSK is vulnerable to offline attack.
WPA-TKIP has been cracked.
TO AVOID THESE PROBLEMS:
1. USE WPA-AES or WPA2 instead of WPA-TKIP (or WEP)
2. USE A PASSPHRASE WITH MORE THAN 20 CHARACTERS. Examples:
BAD: "vintage wine"
GOOD: "floor hiking dirt ocean"
(pick your own words, even longer is better)
FOR HIGH SECURITY, USE MORE THAN 32 CHARACTERS.
