[Q] What are the points when choosing a Wi-Fi router?

[A] First, let's check the corresponding Wi-Fi standard.

The communication speed of Wi-Fi varies greatly depending on the standard. As of October 2021, the latest standard for Wi-Fi is "IEEE 802.11ax", also known as "Wi-Fi 6", and the theoretical maximum communication speed reaches 9.6 Gbps.

On the other hand, "IEEE 802.11ac (Wi-Fi 5)" one generation ago is 6.9 Gpbs, and "IEEE 802.11n (Wi-Fi 4)" two generations ago is only 600 Mbps.

As you can see, the communication speeds vary greatly, so be sure to check the compatible Wi-Fi standards when purchasing a Wi-Fi router.

However, even if it supports the same IEEE 802.11ax, the maximum communication speed differs depending on the Wi-Fi router. Specifically, while some products support a communication speed of about 4.8 Gbps with a Wi-Fi connection using the 5 GHz band, some products have a maximum communication speed of about 1.2 Gbps even with the same 5 GHz band connection. There is also.

Therefore, when you actually purchase a Wi-Fi router, you should check not only the corresponding Wi-Fi standard but also the maximum communication speed.

Also, since the processing capacity differs depending on the Wi-Fi router, the recommended number of connections also differs depending on the product. Especially if you have a large number of devices connected to your Wi-Fi router, you may want to check the recommended number of connections as well.
