Clear Your Router Congestion To Get Maximum Speed By Your ISP

Your ISP may promise you 2-5 MB Internet access and above, but some times we get a speed much lesser than promised becouse our  router may prone to congestion. Generally Routers can congested if their incoming packet buffers get full. When this happens, the router drops packets, and bandwidth suffers. In addition, streaming media such as videos may drop packets, and the
video may stop in between frequently, or you may not be able to view it all.
Windows Vista and Window 7 includes a lesser known tool called Explicit Congestion Notifcation (ECN) that may help for this kind of problem.

Caution: This tool is turned off by default because most of the routers does not support it.Turning on this feature for an unsupported router may even create worse problems.
However, there is a way to find out if your router supports ECN and then to turn on ECN from the
command line.

Follow the following steps:

1.      Run the Internet Connectivity Evaluation Tool :Make sure you’re logged in to Windows as an administrator. Then go to www.microsoft.com/windows/using/tools/igd/default.mspx and agree to the terms.
2.     Install ActiveX Control:When you agree, on the page that appears, Microsoft will attempt to install an ActiveX control. Your Internet Explorer security settings will most likely block the attempt. The Information Bar will light up yellow. Click it, and from the menu that appears ,select Install ActiveX Control.
3.     Start Testing:Follow the prompts for installing the software. A new web page will appear. Click Start Test. After several minutes of testing, you’ll see a results screen.

If your router supports it then your are ready to turn on ECN.
first run an elevated command prompt(Administrative privilege) by typing cmd at the Search box and
pressing Ctrl-Shift-Enter.
At command Line: netsh interface tcp set global ecncapability=enabled

To turn this feature off: netsh interface tcp set global ecncapability=disabled
