Prioritize specified devices such as Amazon "Fire TV Stick"

　The masterpiece explains how to improve the radio wave condition of home Wi-Fi, but the time spent at home has increased due to the epidemic of the new Coronavirus infection (COVID-19), and the wing magazine AV Watch will be July 14.Article "The paid video distribution service usage rate is Amazon.As you can see in the significant increase in video viewing by self -restraint, the VOD (video -on -demand) service that allows you to freely enjoy movies and programs online is gaining popularity.

　Therefore, the popular Amazon "Fire TV Stick" is explained due to the increase in home time.There is no manual in the package, so if you don't know it, there are some things that are a little addicted.With the explanation so far, you should be able to watch the video by connecting the Fire TV Stick to the 5GHz band's home Wi-Fi.From the last time, we have explained techniques that can be used for troubleshooting video playback on Fire TV Stick.

List of articles series "I don't know" of home Wi-Fi!

　Last time, I tried using "Advanced QOS", a function of Buffalo Wi-Fi router, to prioritize video data communication.

　This is easy to set and the effect is easy to understand, but it is difficult to be actively involved from this side because it is automatically determined whether the type of data to be communicated is a video.So, this time, let's adjust the priority of communication by specifying the device using the function of "device control".

　First, before setting on the Wi-Fi router side, check the IP address that is automatically distributed by DHCP on the Fire TV Stick side.From the home screen, proceed with [Settings] → [My Fire TV] → [Version Information] → [Network] and displayed it in the "IP address" item.

　The priority of communication by device control is controlled based on the IP address assigned for each device.Utilizing this function not only gives priority to the communication of the device, but also restricts the bandwidth when using too much.

　For example, a combination technique, such as giving priority to video playback of Fire TV Stick and restricting videos on other devices such as smartphones (the bandwidth is restricted, so the playback quality drops).

　Once you have confirmed the Fire TV Stick IP address, proceed with the device control setting on the Wi-Fi router side.Log in to the setting screen and select [Device Control] (there is also a "Device Control" button in the Advanced QOS).

　Next, let's display the tab with [IP].A list of devices connected to the Wi-Fi router will be displayed. Find and click the Fire TV Stick IP address.

　In the [Advanced QOS] item, set the device that you want to increase the priority to [Priority 1 (high)], and in the device you want to lower, set it to [Priority 3 (Middle)] or [Priority 4 (Middle)].。Check the [Device Detection] [Display this terminal even if this terminal is not detected].

　With this setting, you can prioritize or limit the data communication of the device.When using a device control function, communication is controlled according to the priority set for each device, regardless of the type of data or video.

　For this reason, simply increasing the priority is small, but if the priority of other devices to be used at the same time is reduced, the communication bandwidth will be released, so a device with higher priority.Video playback is definitely comfortable.However, if you lower it to [Priority 6 (low)], be careful as communication will be delayed to the punishment level.

　The setting of this device control is set at the same time as the Advanced QOS.Device control is one of the functions of the advanced QOS, but the settings on individual devices are applied with priority.In other words, if you prioritize Fire TV Stick and give priority to "Video Watching" in Advanced QOS, communication of video viewing on Fire TV Stick will be the top priority.At this time, if you watch a video with a low -priority smartphone, communication is limited even if "Video watching" is given priority in the advanced QOS.

　You may be wondering whether to use this device control or the advanced QOS described last time.In such a case, first try the advanced QOS that can be set casually.

　As I checked last time, the data when watching videos on the Fire TV Stick is recognized as "Video Watching", so if you just want to give priority to this communication, there should be no problem using Advanced QOS.

　If the type of communication data is not recognized by the router as expected, or if you want to control the priority of communication by smartphone or tablet, it is better to use the device control function.

　If you use a mobile Wi-Fi router, if it has similar functions (although there are few such products), to reduce the purpose of narrowing the bandwidth so that the communication capacity is not restricted.Can be used.

　If you want to temporarily turn off the function of the device control, you can turn off the "Advanced QOS" switch on the setting screen.Also, if you do not communicate simultaneously on multiple devices in the first place, there is no need for such QOS -related settings.
