You will have lag no matter how good your connection is.

1. Where the server host is located
2. Other people connection

You can have the best connection but still have some lag in there. So you really can't get ride of lag that easily.

And lag is just how fast your net/console catches up to the server or host. If it keeps up with it faster than less lag. If it does not than more lag.
