ok, I bought a new MBP, and i got the free hp C4780 wireless printer with it. I'm using WPA2 Personal, and I CAN NOT get the wireless to work. I connect the mac to the printer with the usb cable, it sees my network, but it will not go past that point. I know the next step is to put my wireless key in but it never gets to that point. Has anyone had the same problem?
