Welcome to our forum, I am sorry we were a bit slow getting here but we will do our best to help now.
Your line and hub levels look good, the area has a few peaks of high traffic in the evening and this may impact you a bit although it is not at a level where we would escalate yet. Do you find it is just a problem mainly during the evening?
Just to be sure are you connecting with wireless or Ethernet lead when you experience the high pings?
Does a traceroute to the game server reveal anything?
