"Wi-Fi tethering" that uses the line of the smartphone to connect to the Internet of the PC

"Wi-Fi tethering" that is convenient for connecting your PC to the Internet urgently

Mobile Wi-Fi routers can be ordered and contracted from the Internet, and as long as the device arrives at home, you can start using the Internet line immediately after setting up. I will explain in detail how to use the mobile Wi-Fi router from the next time onwards.

This time, for those who have to connect to the Internet even if they are Sugu, I will introduce a method called "Wi-Fi tethering" that uses the mobile line of the smartphone via Wi-Fi.

Mobile lines are also useful enough for remote work internet connection

Wi-Fi tethering is useful when you need to connect your PC to the internet urgently. However, when you start using it, the giga of your smartphone will be used hard and the battery consumption will not be odd. So, check your contract and use it with all your heart. For au and SoftBank lines, a separate application is required to use tethering. Whether it is paid or free depends on the contract plan.

Keep in mind that with a communication speed of 128Kbps, which is limited when you exceed the capacity limit, it's almost impossible to use for remote work (you can barely send and receive email). If you're tethering, switching to a larger contract is a must.

For example, NTT DoCoMo's "Gigaho" plan is suitable for such large-capacity communication because it has 60GB of high-speed communication and a maximum of 1Mbps even if communication restrictions are applied. Voice calls are also possible, and the monthly charge (excluding tax) is 6980 yen (during an increase campaign, usually 30GB).

Alternatively, you may prepare a separate SIM for data communication only with the MVNO. By the way, with OCN Mobile ONE, the SIM card plan for data communication with a capacity of 30GB is 5380 yen per month. Even with such a large capacity plan, if you do not turn off the tethering setting when you are not using it, you will end up in a situation where low speed communication will occur due to capacity limitation when you try to use your smartphone outside. shell.

In Wi-Fi tethering on smartphones, the device name set on the smartphone is often used as the SSID. This SSID will be notified to the surroundings via Wi-Fi radio waves. The naming method was mentioned earlier in this series, so please refer to it.

Tethering on iOS

On iOS, use tethering by turning on [Allow other people's connections] in [Internet Sharing] from [Settings]. It is easy to understand because it is displayed as big in the notification bar while using it.

Since the "name" registered on the smartphone is used for the SSID, pay attention to whether a real name such as the real name or "Shunichi Murakami's iPhone" is set here, and change the naming to one that does not identify the individual. shell. In addition, there are many cases where this name is unknowingly changed to the real name at the time of initial setting.

First, check [General] → [Information] → [Name] from [Settings]. Tap to change if necessary. This will be notified to the surroundings as an SSID Tap [Internet Sharing] in [Settings] Turn on [Allow other people's connections] Set the encryption key in "Wi-Fi" password. When you connect a PC etc. to the smartphone that starts when you tap [Done], it will be displayed in the notification bar. You can check how much you have used by checking "Internet sharing" in [Mobile communication] in [Settings]. You can also reset the cumulative total by scrolling the page to the bottom and tapping [Reset Statistics].Let's use it to check overuse

Tethering on Android

On Android, it depends on the model, but it is turned on with "Wi-Fi access point" or "Wi-Fi tethering". The setting in OPPO (based on ColorOS 6 / Android 9) was a little confusing, so let me show you as a setting example for reference.

Tap [Other Wireless Connections] from [Settings]. In the case of OPPO where there is an item called [tethering] in [tethering and portable access] and [network and internet], this is the demon gate. It seems that you will select [Wi-Fi tethering] [* 2], but here the correct answer is to select [Personal hotspot].

[* 2] …… [Wi-Fi tethering] here is a function to share Wi-Fi at home, etc., and mobile lines are not shared.

For such a screen, switch on [Internet Sharing], which is advanced in [Portable Wi-Fi Access Point]. Tap [Personal Hotspot Settings] [Name] is sent as SSID. Set the encryption key in [Password]. Tap [Save] to use it.If you set this for the first time, you can check how much you have used by checking the SIM information that you can start using with just the [Internet sharing] switch.

From the next time, I will explain how to choose and use a mobile Wi-Fi router.
