Korona-ka, whose convergence is hard to see. If the work at home is temporary, even those who thought "Is it okay to use pocket WiFi?" "It's a little old, but my router can still be used", isn't it becoming unsatisfactory?

Even if you draw a high-speed optical line, you cannot expect the effect if the Wi-Fi router in your house is still the old standard. Why don't you switch to a wireless LAN router that supports the latest standard "Wi-Fi 6" at present?

"Wi-Fi 6" is also known as "IEEE 802.11ax". From September 2019, the Institute of Electrical and Electronics Engineers (IEEE), which is formulating the standard, has changed "IEEE 802.11n" to "Wi-" because it is difficult to know which is the latest in a, g, and ac. There is a history of changing "IEEE 802.11ac" to "Wi-Fi 5" and "IEEE 802.11ax" to "Wi-Fi 6" in a number system.

Wi-Fi 6 can deliver 1.4 times the theoretical communication speed compared to Wi-Fi 5. In addition, Wi-Fi 5 can only communicate in the 5GHz band, but it supports both the 5GHz band and the 2.4GHz band. Since it can be combined according to the situation, stable communication can be achieved.

If you are going to buy it, you can say that it is compatible with Wi-Fi 6, but there are some selection points among them. The number of connections, maximum connection range and security.

If the number of connected devices is large, it can be used for smart home appliances that will increase in the future, and of course, even if each family member is watching videos on their smartphones or sending and receiving heavy data on their PCs, they will not interfere. I'm done.

The maximum connection range is good, but if you don't have a detached house, most wireless LAN routers will cover it. However, if you are worried that the radio waves may not reach every corner of your house, you can use one mesh Wi-Fi (slave unit to increase the radio wave strength, the same SSID, simultaneous firmware update, etc.). It is recommended that you can easily assemble (the appeal is that it is as easy as handling a wireless LAN router).

If you work from home, security features are also a concern. If it is compatible with the latest encrypted communication standard "WPA3", it is possible to prevent unauthorized login from the outside due to dictionary attacks and brute force attacks.

The recommended products based on the above points are as follows.

TP-Link Archer AX10 AX1500 Wi-Fi 6 Router

It is a Wi-Fi 6 compatible wireless LAN router that supports speeds of 1201 Mbps in the 5 GHz band and 300 Mbps in the 2.4 GHz band. Equipped with four high-performance fixed antennas, it supports up to a size of about 3LDK. Simultaneous connection with dozens of terminals is possible. It also has a beamforming function. If the client is a compatible terminal, more stable and powerful communication can be performed. In addition to WPA and WPA2-Enterprise, WPA3 is also used for Wi-Fi security. You can send and receive work data with confidence.

Equipped with 4 Gigabit Ethernet ports on the back. If you connect a PC, smart TV, game console that requires an internet connection, etc., more stable and high-speed communication will be possible. With the WPS button, you can easily connect to the device without having to enter a lengthy encryption key. The selling price on Amazon is about 6600 yen, which is good for cospa. Now you can use the 1000 yen OFF coupon.

Buffalo WSR-3200AX4S-WH

A talented group that cannot be imagined from the appearance of a colon. It has a simple appearance with four built-in antennas, so you don't have to worry about a protrusion (antenna) sticking to your child or pet, or your child or pet may break the antenna. It also has the advantage of being comfortable to put in the living room and easy to clean.

The connection range is up to 3 stories for a detached house and up to 4LDK for an apartment. With Wi-Fi 6 and beamforming support, stable and powerful communication is possible. The maximum communication speed is 2401 Mbps in the 5 GHz band. You can exchange files at work and download videos quickly.

Security is also substantial, and it supports WEP, WPA2-Personal, WPA3-Personal, etc. The number of connected units is several tens or more. It is also possible to restrict MAC access to up to 64 terminals. It is a wireless LAN router that can make use of past assets such as "wireless moving function" that can take over the connection of the existing wireless LAN router as it is, IPv6 support, etc. The Amazon selling price is about 11,500 yen.

ASUS RT-AX3000

It is a 4-antenna wireless LAN router with good cost performance, which is highly functional even though the selling price on Amazon is about 15,000 yen. If it is a detached house, it is 3 stories high, and even if it is an apartment, it is compatible with the size of 4LDK, and it is also compatible with the mesh Wi-Fi system, so there are places where the radio wave connection is poor due to sturdy walls and large furniture. However, you can easily expand the connection range by combining multiple ASUS routers.

Since it supports OFDMA that subdivides one band and communicates with multiple terminals, the number of connected devices is 64, which is a necessary and sufficient number. By doubling the frequency band to 160MHz, we have achieved a maximum communication speed of 2402Mbps in the 5GHz band. WPA3, a new standard, is used for Wi-Fi encryption. In addition, Trend Micro's "Ai Protection" is also installed, giving you a sense of business-grade security.

Linksys E9450 Dual Band Wi-Fi 6 Router

Wi-Fi 6 compatible, 160MHz frequency band is used, so the maximum speed in the 5GHz band is 4804Mbps, which is an ultra-high speed easy mesh compatible router. With 4 built-in antennas, it has a connection range of up to 230 square meters and can be connected to more than 40 terminals. Only Linksys can easily build a mesh Wi-Fi system that can improve the radio wave condition and expand the connection range.

Of course, it is equipped with OFDMA technology and has low latency. It also meets the needs of those who want to enjoy online games. In addition to WPA2-Personal, the latest WPA3-Personal is also used for Wi-Fi encryption. In addition, automatic firmware updates keep you up-to-date with the latest security patches, so you can exchange work data with peace of mind.

Equipped with 4 Gigabit Ethernet on the back. In addition, there is also a USB3.0 port, so you can build "My Cloud Storage". You can easily connect to the client with the WPS button. The selling price on Amazon is about 18,000 yen.

It is a Wi-Fi 6 compatible wireless LAN router that supports wide band (160MHz). Since it can communicate at a maximum of 4803 Mbps, high-quality videos can be downloaded quickly. The antenna is a built-in type. With a total of 6 antennas, 4 in the 5GHz band and 2 in the 2.4GHz band, there is no blind spot for radio waves even in the size of a 3-story single-family house or 4LDK condominium. Since it is a vertical type, you can hang it on the wall without any extra space.

Equipped with OFDMA technology, there is little delay even when 30 units are connected at the same time, and communication is not interrupted. In addition, it supports beamforming and can send radio waves powerfully. Security also supports WPA3-Personal. There is also a compatibility mode with WPA2, so you can connect to existing WPA2-compatible terminals with confidence. The guest port function also supports visitors.
