I've been having issues lately with really bad lag spikes and now i'm thinking it's my connection. At first I was thinking it was my old router (which I was having over heating issues) so I replaced it recently with an Asus RT-N66U. My modem is a Motorola SB6121.
As seen below I have a pretty good connection. It is shared with several people and many devices, but I've experienced the issues with wireless disabled and only my computer plugged in. The reason I'm thinking it is my connection is I experienced it over wow and vent the other day at the same exact time.
I'm a bit lost at this point as to how or what I need to remedy my problem.
