Sometimes, out of sudden, our internet connection seems to break. Clicking here & there only shows a page cannot be displayed.
There are few things can be done :-
1. Reboot the ADSL modem. Most of the time, this should resolved the Internet connection problem.
2. Repair the LAN connection.
If you are able to see computer icon on the windows taskbar, right mouse click on it once. Select Repair.
3. Restart your computer.
4. If all fails, it's time to pick up the phone & call the service provider.
