Wireless internet validating problem
How can I diagnose my internet connectivity problems?
DNS servers are responsible for translating an alphanumeric name, such as into a physical IP address, such as 184.108.40.206. I like to ping 220.127.116.11 because it's an easy address to remember.
If the ping is unsuccessful then there is a deeper problem with the connection and you should continue on to the next section.
If any one link in the chain is broken, the connection won't work.
However all the user may experience is a web page won't load.
Diagnosing a failing Internet connection can be fairly complicated.
This is mostly common on windows machines but it is also possible on OS X as well.(Note: on OS X, this software would most likely present itself either in the menu bar at the top of the screen, or at the very bottom of System Preferences) Anything that is anti-virus, anti-spyware, or firewall related could be the culprit.Once you have identified any type of anti-virus, anti-spyware, or firewall software running, start by disabling the software altogether.If disabling the software altogether has no effect, continue to the next section. Malware: check for malicious network layer software (Windows) Equally common (though these days perhaps more common) to friendly firewall software are malicious forms of malware: viruses, or spyware, which either block or re-direct your network traffic.Anything malicious of this nature can be interfering with your network interface and cause all sorts of problems.
