Netgear 7900P Router Won't find one website

> [...] Suddenly, this website won't load through my Router to any wifi
> device or laptop. [...]

   Where, exactly, is "this website" running?  "won't" is not a useful
problem description.  It does not say what you did.  It does not say
what happened when you did it.  As usual, showing actual actions with
their actual results (error messages, LED indicators, ...) can be more
helpful than vague descriptions or interpretations.

   Where is your test browser running?  What are you using as a URL?
Name or IP address?  What is the actual error message?

> [...] No one else in other locations is having this issue [...]

   What is the URL which works from the outside world?  Name or IP
address?  If name, then to what IP address is it resolved?  What is the
WAN/Internet IP address of the router?

> [...] I tried re-setting the router and the modem [...]

   What is your "the modem"?  Modem or modem+router?

> Ping testing through the router shows a time-out.

   "Ping testing" from where to where?  Actual command?  See "As usual,
[...]", above.

> [...] I have also done a hardwire connect directly to the cable modem
> and the site pings and loads fine which suggests the router is the
> issue.

   Again, this non-description conveys no useful information.  See "As
usual, [...]", above.

> Does anyone have any ideas how to correct this?

   Without some actual information on what you're doing, and what
happens when you do it, there's not much I can suggest.
