Can't connect my Cannon Pixma MG6650 to Router.

Apparently you can enter the same command into a Windows command entry screen:-

arp -a

This should display your printer, router other devices...

Hi JD072015
Are you still having problems?
I have the same printer and spent many hours over many days trying to get it to print wirelessly (scanning wirelessly worked ok!!)  
If you still haven't got it working I suggest you try:-
1) Set up wireless via the printer on screen options (I believe you have already done this)
2)  Go to Devices and Printers and use the add printer option which should search for your printer and allow you to add it .
3) Install at least the Canon MP drivers from the Canon CD.
4) Check under printer properties to make sure your printer is connected to the correct wireless port.
You may need to reboot after each step to make sure the change has been recognised.
I am using Win7Pro 64bit.
If it still does not work came back and I will help you make sure you have fully uninstalled your previous attempts.
Hope this helps.
