Then again, for a password that I seldom have to use, like my router at home, I personally wouldn't have any problem with using one of those random, nonesensical passwords and putting it on a sticky on the bottom of it.
Currently have, I think, 10 wireless devices to manage in my home (laptops, printer, smart phones, etc.) and occasionally have family or guests that would like to access it when they are over.
Having a network password that is easy to remember is a definite advantage for me.
The length, complexity and unguessability of a wireless key has a significant impact on the chances of an attack against WPA-PSK being successful.
I guess my question is what the necessity for mixed case, numbers & letters, and special characters really is.
For example, to a password cracking program, is correcthorsebatterystaple (the example from the xkcd comic) any more or less hard to guess than any other 25 character long string? A cracking program wouldn't know not to check for mixed case, etc, would it?
My understanding of this approach to using long, but easy to remember, passwords (I've had other IT professionals recommend it as well) is that the length alone is what makes password cracking unlikely due to the sheer length of time needed to find the right combination of characters.
