Ipconfig Commands For Fixing the Internet
A few days back, my Internet connection was giving me a lot of problems. For some reason it wasn’t opening this site, when it was able to open all the rest of the sites of the world :S.
A little Google-ing got me a pretty handful of IP command lines that can be used to fix Internet connection problems from Command Prompt.
To open Command Prompt, click the “Start” button and then go to “All Programs”. Finally go to Accessories in the top, and click “Command Prompt”. This will open Command Prompt where you can use the commands given below.
