I really question the value of making passwords hard to remember with numbers, symbols, etc.


For the wireless key, you're typing it in approximately once per device. It's easy to attack wireless networks, and either hard or impossible to detect an attack in progress. The length, complexity and unguessability of a wireless key has a significant impact on the chances of an attack against WPA-PSK being successful.

Assuming that there is some legitimate user on the wireless network, this adds about ten seconds to the effort for the attack.
