canon mx472 wps button

I had to unhook the printer to get a paper jam removed. When I hooked it back up, I got the "press the WPS button for 5 seconds....." message. There is no button of any sort on my router, so let's not get on that ribbon. This is a wireless printer but I have a cord hooked into one of the usb slots. Maybe I'm not using the wireless function? If so, how do I work around it?

Thanks
