as the guys have said while other players can influence what you see e.g. induce lag with print screen, wingtip smoke rapid flashing of lights it is more than likely your internet settings and connection that is at fault.
make sure no-one else is using wi-fi to your pc when playing, make sure no programs are updating automatically e.g. anti-virus and windows and then post your results from ping plotter to the dogz server.
The most important measure is to see if the end host was reached without excessive latency or packet loss. If it is reached without problems appearing at the end host itself, then any apparent issues in the route in between are irrelevant, and may be due to low priority or rejection of ICMP ping requests in the route. Any issue seen in a traceroute that does not carry through to the end host (e.g. packet loss or increased latency) is not a real issue. Any issue that does carry through, however (that is, starts at one hop and happens at all the subsequent hops), may be an issue with the route.
In my opinion, for gaming, under 100 is best , anything over 300 is problimatic , however there is very little you can do about high pings unless the cause is the first hop. this is the link from your pc to your service provider hub, called the bam server. IF the fault is here then you should contact them and get hem to trouble shoot the problem. If you are on dial=up then it could be your phone line, the phone junction or the server is overloaded and you would need to check all of these out.
here is my results and I get no lag
