What is a reasonable PSK length for WPA2/PSK/AES for reasonable security? The PreShared Key can be between 8 and 63 characters long (or exactly 64 hex characters). You want a key long enough to defeat a brute force attack (i.e. it would take 1 month of computing power to crack the key) and minimize the errors when users enter the key on their computer.
I have this problem too.
