After much diagnosis, I realized there was no other option but to reset the white belkin netgear wireless router, and I finally did about 1:30am, and all seems well after that. I reset the connections to the APG systems in the back, and the backlog of latent connections on Nagios began to clear out. (correction- At 2:15am, still several Nagios services reporting as critical, but are wholeskycamera related to network loss.
Hope I didn't screw things up too much- I blame the lack of sleep!
Thanks, Tim
