About a week ago I started getting massive lag spikes while playing online video games like team fortress 2. A lag spike happens every few minutes or so and is very frustrating. I am using wireless but I don't think it's a problem because I have only started lagging a week ago and no one else in my household is using up all the bandwidth. 

I have ran a traceroute with one of the valve game servers and here are my results:

Tracing route to eat.valve.net [192.69.96.1]

Is there anyway to fix this problem?
