D6200. WPD is not connecting. 403 error. Possible browser error or timing out.

Thank you for spelling out the information that would help you to help me.  As a first time user of this community I was not sure of how to get the ball rolling so thanks again for your detailed response. 

I have resorted to technical support via phone from one source and via remote login by the printer tech support team.  Unfortunately neither could resolve the problem although both helped ruling out some potential issues.  I have since called in a technician and been able to confirm that the printer's ability to communicate with WIFI is indeed the issue and so I am heading out to buy a USB cable.

Again, thank you for responding to my post.
