Wireless on MG3620 - light shows it has a connection but I cannot find it on any network

[NCguy]

I have set up the Pixma MG3620 but I cannot set up the wireless printing.  The light is on and shows it connected to a network but I cannot find which one (I needed a small unit and this one doesn't have a screen).  I followed the directions but holding down the wireless button to get the power button blinking does not work.  I have held it down multiple times, each time for over 15 seconds.  I am at a loss.  Is there a way to find it?  Should I buy a USB to USB cord and try to set it up connected? I don't want the wire.

Thanks for the help....

SOLUTION: Put in the ink cartridges 🙂 

Just figured that out. No idea why that's a thing, but it's a thing.
