There are different problems that occur during browsing the internet. These problems are caused due to several reasons. Some times sites are working properly and fast. But some times there are some problems occur with our servers. Our servers open BSNL and opens DNS servers, so that they can update the server. To solve this problem, you can use DNS server to open any specific website.

DNS meaning

DNS is the abbreviation of Domain Name System. This is a computer language to define any address or URL.

The DNS is in short, defines the address of different websites. For example, if you type any website in the address bar of your browser, it will automatically find the DNS server so that it could connect with the website. Without the DNS server it is not possible to connect to any website. On DNS server demand the server answer that contains an IP address. This IP address actually determines the location of the source.

Use of different DNS, when DNS default is slow

This is a normal problem when domain is moved and ISP banned the server to connect with any website. In such a case you can not view the websites and content of the page.

How to Optimize Your Internet Connection to Get 100 % Bandwidth

Most of Internet connections are working below capacity. A simple bandwidth test would reveal that your own Internet connection is working well below its capacity. some times below 60% of the bandwidth is utilized. Below are some of the tricks I have collected that may help you get most juice out of your internet connection.

Increase bandwidth by tweaking QoS in Windows XP Pro

The following tweak applies only to Windows XP Professional edition. The default system behavior is that all 100% bandwidth is available, however, if there is a running application that indicates to the OS it needs to send high priority/real time data, then as long as it has the socket open, Windows XP will restrict “best effort” traffic to 80% of the bandwidth so that high priority traffic can be accommodated. Basically, applications can make this request to the operating system for QoS support using the QoS application programming interfaces (APIs) in Windows and this only applies if a specific app is requesting QoS.

If you’d like to change how much bandwidth is reserved for QoS (the default is 20% of the total bandwidth), do the following:

  • Make sure you’re logged in as “Administrator” (not just any account with admin privileges).
  • Navigate to START>Run and type: gpedit.msc
  • Navigate to Local Computer Policy > Administrative Templates > Network > QOS Packet Scheduler
  • In the right window, double-click the limit reservable bandwidth setting
  • On the setting tab, check the enabled setting.
  • Where it says “Bandwidth limit %”, change it to read 0 (or whatever percentage you want to reserve for high priority QoS data)
  • Click OK, close gpedit.msc
  • Under START > My Computer > My Network Connections > View Network Connections, right-click on your connection and under Properties (where it lists your protocols), make sure QOS Packet Scheduler is enabled.
