So, my network problems were not quite over. One of my printers (cards, magnets and invoices) is connected via wireless and... you probably see this one coming... refused to communicate with my computer when I got fired up to get orders out.
I spent the morning troubleshooting, and did FINALLY get it working again. It was a stupid error on my end (a .0 instead of a .1 in the IP address), but oh, so very, very frustrating, and it definitely throws the schedule of my day off. No Torn World or AOF today, I suspect.
