I'd like to know how to maximize the network utilization on my computer.
I did some searches but had no luck.

There are 4 computers in my house, and all are connected to a router.
We have a cable connection. The speed shows 100Mbps.

But, on my computer, I see that the network utilization never reaches its maximal utilization. The max. utilization when I am downloading something is 3%.

What type of internet connection do you have? I don't think you have a 100 Mbit internetconnection. If you have a 2 or 3 Mbit internet connection (max download speed around 240 kbps (2Mbit)/ 370 kbps (3Mbit)) and you download with max speed it is exactly 2 / 3% of your maximum network connection (100 Mbit). So probably you have a 3 Mbit internet connection. The only way to get max network utilization is by copying large files from one computer to another in your network.

Your download is limited to the speed of your WAN Modem, not limited by your internal network which is 100MBit/s.
Your WAN modem is probably around 4 - 6 Mbps, so that's as fast as you'll ever be able to download from internet. The 100MBit/s is the speed at which you can transfer data over your internal (LAN) network only.
