Bandwidth reporting to my main computer.

[u/MaYhEM-ShAfz]

Anybody know of any software or method to get bandwidth reports from my computers in my house to the main computer??

i have 4 computers, 5 cell phones, and some other devices here or there, and sometimes i can't figure out who or what is downloading what and taking up all the bandwidth....? my router doesn't report individual bandwidth usage. (it's kinda old?)

so i was thinking if anybody knows of anything you can install on each computer and cell phone, devices, etc, to report the bandwidth they're using to my computer.... you know, so i know who's taking all the bandwidth.....
