You might have came across some error in a while and like most of the people I did look out for it on Google and couldn’t fix my problem. Yes!there was an many articles on this topic, but all seems to be half baked. So I try to sort it out.
Here is the 3 things most people forget to mention in their solutions which is very important if your net is not working even with the green signal on Internet is blinking.
1) First you should check whether your telephone is working properly, chances are they cut off your connection for temporary if you didn’t clear the dues.
2) Another time I was in same problem and so I called the customer service, what they told me instantly fix the error. You have to type ‘pinggoogle -t in run on your computer. It did solve the problem.
3) check your settings on your admin page. You can log to your admin page by typing 192.168.1.1 on Google. Check username, password and other setting if you have no idea of your internet setting, call your Telecom customer care. They should fix this issue.
4) cable problem
If your cable get tangle, there is a chance of broken down or fall apart. So check with another cable or try another way like using wi-fi instead of cable.
5) if you know your broadband username, password and IP addresses then you can manually change it yourself, for that you need: first go to the network setting on your computer, then select IPV4 address and change it manually and save it.
HOPE IT WILL SOLVE YOUR PROBLEM!
