I set up my new MF489dw on my pc w/ Windows7 wirelessly. I set up my iphone 4s w/ Cannon M Print. Set up laptop w/ Windows 7. All worked fine (I did not return to the other two after printing from the additional ones? But now NONE of them work? ...
It was a router issue. I assumed (incorrectly that if the router was up and running for the computers that it was up and running for the printer as well.) Simple solution to a hair pulling problem. thanks for your prompt reply.
