MF4890dw has stopped printing wirelessly after initial set up? windows 7 on computers and iphone 4s

[poynorwife9819]

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?  I have rebooted all of them and the printer.  I downloaded up dated drivers from Cannon's website as well.

Hi poynorwife9819,

If you are unable to print from either your computer(s) or iPhones, please check to make sure that WiFi is still enabled on your laser printer and that the router is active.

If any errors occur, please document them exactly as displayed.

If you've already checked this or the issue is unresolved, find more help at Contact Us.

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.
