No, the initial passphrase just gives it a place to start when generating the 128-bit session key. However, make sure you choose a sufficiently random key that it's not susceptable to dictionary attack.
couple of WPA passphrase questions

Will the size of the WPA passphrase impact in any way the speed of data transmission? I would assume decrypting a larger key would take longer but is it negligable?
AFAIK, WPA changes the passphrase every so often automatically. What is the size of the passphrase it chooses, does it have any thing to do with the size of the initial passphrase I created?
thanks
Not at all because the keysize is always the same. The WPA passphrase is for authentication and is not the encryption key.

It doesn't change the passphrase at all, if you mean the key then yes, they are not the same thing, if it changed it automatically, you wouldn't know what to enter in order to use your machines on the network would you?! :)

David.
Aha! That's what I was confusing, authentication and encryption, two separate "keys".
thanks
