solution for high ping

GhostPrime: Pingplotter is a great tool. (I don't believe its free anymore though) This will tell you if you have packet loss.    Your ISP and the speed had a lot to do with latency, and ping.  Make sure that other devices are not taking up your network bandwidth. This is a big one. I have seen a smart TV kill bandwidth. Windows 10 as well. You have to turn off the Peer-to-Peer updates in the Windows 10 settings.
