Instructions
Choose a closer server. If you are located in Illinois and you log into a server based in Russia, the distance will greatly contribute to a high ping. You can reduce this by searching for a more nearby server.
Upgrade your Internet connection. To play very graphics intense games over the Internet, you need download speeds of at least 4,750 kilobytes per second and upload speeds of at least 1,125 kilobytes per second.
Reduce bandwidth by closing other connections. If you are sharing the connection with a computer, for instance, then shut down all the Internet-based applications on the computer or, better yet, just turn it off.
Connect directly to the Internet. Wireless connections typically add anywhere between 40 to 50 points to a ping rating. Standard Ethernet routers also increase ping levels, but not nearly as badly as wireless routers.
