If your home's internet speed is slow, suspect "line / router / handset"!

When the internet communication speed is slow, there is a problem with the internet line, Wi-Fi router, or Wi-Fi slave unit.

Life without Wi-Fi is no longer conceivable. It's no wonder that laptops and smartphones are connected to the internet at home and at work. Wi-Fi has become one of the living infrastructures. For that reason, it is very troublesome that the communication speed of Wi-Fi is slow. Work may be delayed or entertainment may be ruined by stress. Why is my Wi-Fi slow? Continuing from the last time, in this part, let's clarify the cause and show the way to solve it. [Visual explanation] What to do when the internet at home is slow

■ Three major reasons why Wi-Fi is slow

The slow Wi-Fi is often caused by one of (1) Internet line (2) Wi-Fi router (3) Wi-Fi slave unit. The main reason for the internet line is that the contract plan is slow. Be careful if you have a contract more than 10 years ago or have a plan installed in an apartment. Wi-Fi routers, on the other hand, have the problem of old standards. Wi-Fi routers do not have driving parts such as HDDs and fans like personal computers, and are less likely to break down. For this reason, many people have been using the same product for more than 10 years, but this is the Achilles tendon. Before you know it, the Wi-Fi router becomes obsolete and is left behind in the faster internet world. The same applies to the Wi-Fi handset that a personal computer has. High-speed communication cannot be expected with the handset of the old standard. Furthermore, the usage environment has a great influence. If you move away from the Wi-Fi router or if there are obstacles, the communication speed will drop at once.

The root cause of the increasing number of people who feel that Wi-Fi is slow is that the usage environment surrounding users has changed. With the spread of video services with a large amount of communication and the increase in the number of slave units that access the master unit at the same time, the communication load of Wi-Fi in the home is increasing. In recent years, video distribution services such as Netflix and Hulu have become popular, but many services also distribute in high-definition 4K. Some videos on YouTube can also be viewed in 4K. Viewing 4K video requires a communication speed of 20 to 25 megabits per second (Mbps, 1 million for mega), and if that level cannot be secured, the image quality will automatically deteriorate. Web conferencing, which has become commonplace under the corona, also requires a communication speed of 10 to 30 Mbps.The next page is: ■ Check the communication status of your computer
