Don't know if my own experience is helpful or not, but just wanna share it anyway; I have a C4385 (older model; but the wireless setup part should be similar) and for the 1st time setup on a PC/Mac you'll need to use a USB cable to connect to the printer itself to setup the networking, since by default the device wouldn't have the right IP address to start with; I do have a Linksys wireless router but I only use static IPs so I don't know if this would be any difference if using DHCP instead... and IMHO, you'd like to stick with static IP for the printer since you wouldn't want it to change to a different IP every once in a while when the leased one expires...
