Sometimes due to incorrect settings or failure of the domain name server, the computer may not be able to connect to the DNS server. If you encounter a similar problem, you can fix it…

As an Internet user, I know how it feels when the internet connection is slow. The slowness of internet connection will affect our daily activities such as internet banking transaction, play online games and watch Youtube online.

How to know if Internet connection is slow?

Well, the answer is quite simple. If you try to browse any website and keep on getting error message such as 403 forbidden and page cannot be found. Then you know that something is wrong with the Internet connection. Sometimes, not all Internet slowness issues are related to Internet provider for example Streamyx.

6. Close the Command Prompt window.

7. Launch your internet browser again and start browsing as usual. I hope this simple method will improve Internet connection.
