Oddity between FFXIV and Network

So I run a four computer family network. Each of the four computers plays FFXIV. That is until today.

For an hour I played today without issue, then from out of the blue it stopped working right. After being booted the first time (and as I usually do when this occurs I start a ping series to see if the issue is mine or not, high pings with packet loss usually are us, while low ping packet loss is not. And yet today proved differently through several attempts.) I tried logging back in and found my pings to break apart.

When I start FFXIV severe packet loss occurs crippling the outgoing connection for the entire network and making it impossible for me to play the game. Testing this I found its is only mine, the other three computers can play without impacting the connection in any form.

Now... I have scoured my computer of some strange virus of which none were found. I have uninstalled and reinstalled the game. I've reset my computer. I'm half convinced its the OS. But I am not sure, this issue is strange and bizzare.
