This is a small home network with 6 desktops and 3 laptops. I would like to keep an eye on bandwidth each PC is using, especially games. It’s family use, so I simply don’t want a commercial software, freeware appreciated.

I know I can search Google, but it takes time to try one by one. I just want you guys tell me your experiences. So, what’s the best software for monitoring network traffic?

Thanks in advance.
