is there any method to reserve some bandwidth for wired LAN for windows 7??? Some of them in my network leaves their computer for downloading movies and other stuffs. And I really have my connection so slow even to download a single page...So please suggest something.
You need a router w/ QoS (Quality of Service) feature, but not all of them support it, esp. at the lowest end of the price spectrum. QoS will allow you to prioritize traffic based on different criteria (type, IP address, MAC address, etc.). Without QoS, it's basically first come, first serve.
