One of the most common problems you may encounter is having a "No Internet Connection" status on your device. First, make sure your router is properly plugged in and check if the light indicators are working and flashing. If there are no flashing lights and if there are no signs of activity, turn off your router, unplug it, and wait for a minute or two before plugging it back in. Also, check if the cables of your router are properly connected. Once the indicators light up, then your router is properly working.
Sometimes, having no Internet connection is not caused by your router, but with your device's network settings. If you are trying to connect your electronic device like your laptop or smartphone to WiFi but are unsuccessful, check the Internet settings in your device and make sure it is turned on. However, some Internet connection problems are caused by PC virus or some sort of malware. If this is the case, try doing an antivirus scan and restart your PC or laptop. If the problem persists, contact your PC/laptop technician to solve the problem as it may involve some hardware repairs.
It is highly important for every Internet user to know and understand the basics of Internet connection, as well as troubleshooting common Internet connection problems. Sometimes, these problems can be easily solved without the need of an expert. Do some research and try to learn as much as you, but if you think the connection problem requires some help, it is best to contact your Internet service provider.
