I have been away from my blog for a couple of days. I will blame the super-slow browsing speed of my broadband. The issue is resolved now as I have been told the new IP settings by a Pakistan Telecommunication Limited (PTCL) call center representative.
1. Double click on the local area network connection on the bottom right corner of your desktop.
2. Click on the "Properties" button on the bottom left corner of the local area network connection box. It will open another box titled as "Local Area Connection Properties".
3. Double click on TCP/IP settings to open "Internet Protocol (TCP/IP) Properties".
4. Select "Use the following IP address" option and enter the IPs as shown in the figure.
