I need to throttle the throughput (upload/download speeds) of a single computer on my network, it runs Windows 7.
What software would you recommend to throttle the upload/download speeds of a computer on my network, without limiting my own as well?
Thank you. Last question: Is ISP bandwidth throttling/shaping legal? How do I detect if they are shaping my connection? (I live in the USA)
Your ISP sets the rules. After all it's their network and infrastructure.
Throttling, shaping and blocking on ISP level is meant to improve the overall network performance and customer experience.
As long as they stay within their own Terms of Service I don't see any legal issues.
You can test it at the following page:
