Just this day I got a problem with my online network so I decided to write this helpful stuff.

When you encounter a network problem, some of these command line tools can help you narrow down the source. From the command  prompt in the accessories of your windows:

ping ipaddress ( for example, ping 192.168.0.1) shows whether your computer can contact another computer or network device at a specific IP address. First ping your router to see if your LAN is working, then ping something on the Internet to see if the problem is outside.

netstat gives you a list of all the active TCP/IP ports on your system - this is very useful in  detecting whether a trojan horse has commandeered your  system.

ipconfi /all shows all your computer's IP-related settings. If your computer is having trouble getting online, try ipconfig /renew to refresh your IP address or get a new one.

tracert ip address (for example, tracert 192.168.0.101) reveals every router hop from your PC to another computer or network device. If you start seeing dropped responses, you may be able to tell wether the problem is local.

Hope this some useful tips will help you in troubleshooting your network problems. And if you find this helpful why not subscribe to my RSS feeds and be updated on my post.
