How to speed up download speed

I learned of a way of speeding up our download. It is very simple. We need to do some testing before we settle for the speed. Well, it is like this.

Whenever we connect our modem to the telephone, a new IP will be allocated. This will affect the speed of our download. Hence, we can test the speed by disconnecting and reconnecting the modem to the telephone line until we get the highest speed for our download. Of course we need to have the URL of the file which we intend to download.When the highest speed is found, settle for this and stay put until we switch off our computer.
