Why is the home net late?Thorough elucidation of the three causes (Nikkei style) --Yahoo! News

No matter how new Wi-Fi router you buy, it doesn't make sense if your Internet line at home is slow.

"The speed of the Internet is slow" and "Communications are interrupted during the web meeting."Are you suffering from such trouble recently?The fundamental cause that the Internet is slow is that the communication load on lines and Wi-Fi is increasing.The number of video services with a lot of communication, such as YouTube, has increased, and the opportunity to meet with colleagues at web meetings has increased.It is not unusual for the whole family to access the Wi-Fi router from a computer or smartphone at the same time.In the old communication environment built many years ago, it is no longer possible to respond to this situation.It is necessary to prepare a new communication environment that suits the present era.[Visual commentary] Why is the house online slow?The three causes are easy to understand with photos

■ Isn't the Internet line slow?

There are three main causes of the slow communication speed on the Internet.One is that the Internet line is slow.Users in the old optical line of the megabit class should review the contract.In recent years, high -speed optical lines with a maximum communication speed of 1 gigabit/second (GBPS, Giga are 1 billion) are standard, and services that make amazing speeds such as 10Gbps and 20Gbps are appearing one after another.Now the Giga class optical line is a matter of course.

■ Isn't the Wi-Fi router standard old?

The second cause of slowness is that the Wi-Fi router standard is old.The maximum communication speed of Wi-Fi 4, which was the mainstream until six or seven years ago, was 600 megabit/second (Mbps, 1 million mega).On the other hand, the maximum communication speed of the latest standard "Wi-Fi 6" is 9..6Gbps, about 16 times that of Wi-Fi 4.Currently, Wi-Fi 6 compatible routers can be purchased at a price below 10,000 yen.4 old router users want to consider replacement.

■ Is the standard of Wi-Fi a slave unit OK?

The third cause is a case where a Wi-Fi slave unit provided by PCs and smartphones is a hinder.If the Wi-Fi standard of the slave unit is old, no matter how much a new router is purchased, the performance will not be used.If the standards of routers and slave aircraft are different, they will communicate at the speed of old standards.In addition, the indoor environment with routers and slave aircraft is also important.Radio waves are difficult to reach if the interconnection distance is long, and radio waves tend to decline if there is a metal or reinforced concrete bearing wall on the way.In such a case, the communication environment can be greatly improved by using the relay machine well.(Nikkei PC21 Hiroshi Kotani) [Nikkei PC21 January 2022 Issue published article]
