<< 2022 >> 10 recommended Wi-Fi router models, must-see for those who continue to use old routers!

Computers, smartphones, tablets, televisions, recorders, game consoles, robot vacuum cleaners, air conditioners, and more, these days, all kinds of devices in the home are connected to the Internet. A wireless LAN router (Wi-Fi router) that connects these devices to the Internet is important.

I think that many people are already using it, but if you have trouble connecting in some places at home, the internet becomes slow when your family uses computers and smartphones all at once, the internet is slow in the first place, etc. If you’ve ever been frustrated, it might be time to buy a new Wi-Fi router. Therefore, in this special feature, we will explain the points when purchasing a Wi-Fi router and pick up some recommended models. Please refer to it when choosing a Wi-Fi router.
How to choose the latest Wi-Fi router
A Wi-Fi router is essential for connecting devices throughout the home to the Internet. Since you can connect devices wirelessly, you can connect multiple devices at the same time without the need for troublesome cable connections. If you have a smartphone, you can use the phone line outside and Wi-Fi at home to save the amount of communication on your smartphone.

Even if you want to buy a new Wi-Fi router, there are surprisingly many types in stores and online shops. What’s more, the model number is a list of English and numbers, and the appearance is box-shaped, and they are all similar (although recently there are more and more unusual shapes). Even so, there are many points to check, such as the communication standard and the number of antennas, so it is extremely difficult to choose the model that suits you.

・ Narrow down the products based on the layout of the house and the number of users
First of all, if you don’t think about difficult things and want to find a Wi-Fi router that suits you for the time being, you should choose based on the floor plan and number of users in your house. Buffalo and NEC Platforms, which are popular on Kakaku.com, publish floor plans, number of users, number of connections, etc. For example, “If it is a 3-story detached house and the number of users is 6 people, ○○”, “If the number of people is 2-3 people in a 2LDK condominium, ○○”. This should allow you to quickly narrow down the model that suits you.
The difference in floor plan and number of users is the difference in the number of antennas installed. The more antennas there are, the faster the communication speed and the farther the radio waves can reach. Currently, the highest class model has 8 receiving antennas and 8 transmitting antennas, and is labeled as “8×8” in catalogs. For detached houses, there are many 8×2, 4×4, and 3×3 models for 3-story models, and 2×2 for 2-story models. In addition, it is sometimes said that it is enough to have as many antennas as there are walls, so it would be a good idea to simulate your own usage environment once.

As a point of caution, choose a product that has a little more room than the layout of your home and the number of users. The information released by the manufacturer is for the case where the Wi-Fi router is installed in the middle of the house. Actually, I think that it is rare to install a Wi-Fi router in the middle of a house. For example, if you put a Wi-Fi router in a corner of your house, it will be difficult for radio waves to reach rooms far from that room. Therefore, if you live in a 2LDK apartment, it is safe to choose a higher-grade model, such as a model for 3LDK, and a model for 4LDK if you live in a 3LDK.
・ If you choose now, Wi-Fi 6 compatible model
Let’s also remember the difficult communication standards firmly. First of all, “IEEE802.11○”, which you often see in Wi-Fi router catalogs, is an international wireless standard. For clarity, they are sometimes referred to numerically as “Wi-Fi 6,” “Wi-Fi 5,” and “Wi-Fi 4.” The numbers 6 and 5 represent generations, with Wi-Fi 6 being the newest.

There are various differences in communication standards, but first of all, the frequency band used and the maximum communication speed are different (see the table below). If you subscribe to a high-speed optical line but are using an old Wi-Fi router that supports 2nd generation IEEE802.11b or IEEE802.11g, you can use the latest Wi-Fi 6 or Wi-Fi 5 compatible router. You can expect an increase in communication speed just by replacing the model.

Also, notebook computers that support Wi-Fi 6E have appeared. Wi-Fi 6E works in the same way as Wi-Fi 6, but it has more available channels. It is said that interference can be easily avoided by using the 6GHz band, which has not yet been approved in Japan. A compatible router has not yet been released, but when choosing a new laptop, it may be a good idea to choose a model that supports Wi-Fi 6E.
Keep in mind that different frequencies have different characteristics. Wi-Fi uses two frequency bands, the 2.4 GHz band and the 5 GHz band. The 5 GHz band has little radio interference and stable communication is possible because there are few compatible devices. The communication speed is also fast, but it is vulnerable to obstacles, and depending on the location, it may be more difficult to connect than the 2.4GHz band. On the other hand, the 2.4GHz band is compatible with many devices and can be connected to many Wi-Fi devices. It is strong against obstacles and does not break easily even through walls, but there are many devices that support it, and the speed may be slow due to congestion. Depending on the situation, the ease of connection and communication speed may change.
