My daughter has an HP Envy 7640 printer, which prints just fine... trouble is she moved recently and when trying to reconnect her computers and printer to new network, she cannot get the network to recognize her HP printer... or perhaps get her HP printer to connect to the network. The computers connect fine, but when trying to print wirelessly, you just can't get there... Have spent hours on the phone with the internet provider, and more hours on with HP. Nobody seems to know what is causing the problem. HP technician thinks she could fix the router problem, but get access to the IP address. Has anyone else experienced this problem? Were you able to fix it?
