Recently my GF has had some latency in FFXIV, which seemed like packet loss. I did some tests, using 2 different PCs for a couple of games and they both experience packet loss at the same time, even on different games. We are also both connected via ethernet cable.

I downloaded ping plotter and added the IP address of a few games, google (8.8.8.8) and then also our router (192.168.0.1)

The packet loss seems to be almost uniform amongst all other than the router; as you can see in the screenshot attached. Does anyone have any idea why this might be or how I can go about potentially fixing this? And also what it means when all 3 have packet loss but the router here doesnt?
