I just moved to a new home and have a different ISP. My wifi printer, HP Officejet Pro 8625, worked before. Now I can't get it to work, with or without wires. The wizard says my passcode is incorrect. It is correct. I've tried uninstalling and reinstalling the printer. I've changed the IP address on the printer to be the same as my computer. I don't know what else to do. I've removed all other networks. Can someone tell me what to do?
