1 / Decrese bandwith for QOS-AWARE PROGRAMS: as default, Microsoft Windows only use 80% bandwidth for you to access the Web, while 20% use it for "QOS-AWARE PROGRAMS", this procedure will help you take advantage of the residual section that:
- Go to Start> Run, type gpedit.msc> OK.
- Find ComputerConfiguration> AdministarttiveTemplates> Network> Qos> Pack Schduler. Frame on the right, you double-click the Limit reservable bandwith, in the window displays you move through the Settings tab, check the Enable and type 0 in the frame Bandwith Limit (%), then OK. This reduced amount of bandwidth reserves from 20% to 0%.
2 / Edit TCPIP.SYS file: This file management of the Internet connection. First you need to download the file bat has the function of editing TCPIP.SYS here or here. Downloaded, unzip file and run Bat, type Y to agree, when asked to put the disk into the windows you click Cancel. Finally, press any key to close the DOS window, restart the computer.
