I want to understand early, what to do when "Wi-Fi is slow, difficult to connect"
This time, we will introduce what to do when the Wi-Fi environment is out of order. The range of radio waves is not constant, and it reaches neighboring houses and buildings. Some frequencies are shared with other uses. It can be said that radio wave conditions are difficult to see and change easily, unlike wired LAN. I want to understand how to deal with it, thinking that one day I may suddenly fall into a malfunction or trouble.
Try restarting the Wi-Fi router first
If the Wi-Fi, which had been working fine, suddenly becomes slow or frequently disconnects, restart the Wi-Fi router first. Let's start This will reconnect the internet line and reset the Wi-Fi channel to use. This may improve the situation.
The method of restarting the Wi-Fi router differs depending on the model, but for most models, you can turn off the power and turn it on again. Some models can be restarted from the setting screen of the Wi-Fi router.
To restart your Wi-Fi router, turn it off and then on again. Some models can be restarted from the setting screen.

It is better to leave the setting to select. Recent Wi-Fi routers are equipped with an automatic channel setting function, which checks the surrounding radio wave conditions at startup and selects a relatively free channel to use.
However, the signal status is only checked when the Wi-Fi router is activated. If the surrounding radio wave conditions change after that time, the appropriate channel will not be used. By restarting the Wi-Fi router, it may be possible to respond to changes in the radio wave conditions.
If you frequently monitor the radio wave situation and know which channel is often vacant, you can manually set it to that channel and not change it.
Recently, there are also models that can automatically and dynamically select channels according to the surrounding radio wave conditions. These devices can continue to use the optimal channel without rebooting.
