I'm having issues with my EA4500 dropping packets... but not just any packets. Packets from a hop on the edge of my ISPs network - 72.175.111.144. I get anywhere from 10-15% packet loss on this hop but 0% packet loss on any hop before it. I also recieve no packet loss from the same IP if I remove the router from the network and direct connect to the modem.
I've rebooted, I've left unplugged, I've re-flashed firmware. Nothing helps and it makes zero sense to me why it would just drop that specific IP. Has anyone else seen this behaviour?
