Is there a way to limit a whole PC windows XP, or a certain program to use only a certain about of your total internet connection bandwidth?
For example, I have 5 PCs in home all one the same ISP connection. I have one PC that I am trying to backup files online but I can only run it at certain times due to the backup program using ALL upload/download speed. And that makes every other PC super slow.
So if I had a way to tell this PC, or program to use only 10% of the Internet connection I could run it all day long.
The thing you are looking for it called quality of service if you are using network equipment to do it. You need a router that knows how to do QoS. It often leads to performance problems if not done correctly.
