C6300 Router Not Accessing Email Server

Let me preface this with the fact that I am a complete novice.

 

My ISP went down this week, their tech support sent a refresh signal to my router (which is my equipment, not theirs: C6300), and whether that caused the issue, or simply the reset when the service restored, I can no longer connect to the email servers of my shared hosting plan with Hostgator, to pull my emails over wifi.  When I switch off wifi (on multiple devices), I have no problem pulling the emails over the cellular network.  So I believe the problem is isolated to my router.

 

I have tested different outgoing mail server ports, and the problem persists.  I have the current firmware for the router: V2.01.26.

 

I registered my product with Netgear under the guise of 90 days of free support.  But it says that my 90 days of support expired on the date of purchase that I entered.  I don't know if that can be rectified as well via this board or not, but thought it worth mentioning.  Any help or ideas would be greatly appreciated.

 

Thanks!
