I've been profiling my boot times with bootchart and it seems that wpa_supplicant and dhcp take a significant amount of time during the boot process to get up and running and associate with my home router.

The connection works fine - it just takes awhile.
I'm interested in optimizing boot time and don't need network until later. How can I delay the authentication process for WiFi until after I've started X and the system has booted?
