Hi there! You'll find the step-by-step setup guide HERE.

If you've followed the guide and still need help, it may be easier to contact phone support so they can troubleshoot with you one-on-one. They're at 800-OK-CANON (800-652-2666) Monday through Friday from 9am to 9pm, and Saturday from 9am to 8pm (ET). 

i did as the guide said but i still have the same problem, is there another way of contacting the support i cant make phone calls atm, like an email option or online chat

You'll find all of your available support options within your My Canon Account at

to be able to contact support i needed to register my camera but since i didnt buy it in USA i cant register it therefore no support contact for me any other way you guys can help me?

If you happen to live outside the United States, you'll need to contact the Canon company that supports your country or region.  You can find them by clicking HERE and choosing your country from the map.

Hope this helps!
