Speed is very high considering you have a 2 MBPS connection, so that is a great thing.
You cannot lower pings. Since pings are high because of the distance of your house to the internet exchange. Higher the distance, greater the ping. Ping also depends on the internet infrastructure of the countries. If the server is in America, the signals would go to your house to the exchange to America and then to the server, and then back from the server to America to exchange and then to your house. If a server is in Australia for example, it will give higher pings.
So there is no way to reduce pings.
