Lag Spikes

I've been noticing large amounts of spikes while doing anything on the At&t router. I can't manage to play a single match of any game or play a game without consistent drops in the connection. (Blizzard, Steam, Runescape, just browsing the web on Google Chrome and even getting spikes on Discord which roboticizes voices and drags them out.) I ran a Traceroute, Ping and MTR on the Blizzard servers for Overwatch and recieved the following results:

 I'm starting to wonder if the packet filter for port 80 is causing high latency issues and spikes, but would like you to confirm and provide a course of action to solve this issue.
