Your ping depends on the hardware (router, NIC and other devices on your network).
If have Vonage (or other IP phone company, Netflix running or some else is surfing) your ping can be affected.
If your Router is in the living room and you are playing in your bedroom your ping might be affected because of the metal and wires in the walls.
If you are running other services on your computer, the CPU is processing too much, it will affect your ping.
If you'r router has been hacked...you are loosing bandwidth.
Fix: get highspeed internet, try using an ethernet cable vs wireless, removed other network services and devices, check your processes (ensure your anti-virus is not doing a scan at the time of gaming)
Thanks, now i can find a fix to this annoying ping issue.
