Description

From the listing uploaded by “appupdater”.

"Wi-Fi Miller" is an application that can measure and display the Wi-Fi environment such as your home or office. By "visualizing" the Wi-Fi radio waves such as the signal strength and heat map of the currently connected Wi-Fi, we will help you to realize a more comfortable Wi-Fi environment. You can also measure internet speed and Wi-Fi speed. Since you can see the speed of the Internet side such as optical lines and the speed of Wi-Fi communication only and each speed, it is a problem of the line or a problem of the Wi-Fi router when you have troubles such as slow Wi-Fi speed. Very useful when making a distinction. Even if you are using a wireless LAN router other than ours, you can measure using this app. ・ Radio field strength The signal strength of the currently connected Wi-Fi (SSID) is displayed as a numerical value from 0 to 100. The larger the number, the better the radio wave condition. * The displayed values are for reference only. ・ Heat map By measuring the signal strength of each location, you can create a heat map that allows you to easily understand the signal strength of Wi-Fi in your home or office. You can also read the floor plan, so you can see the measurement results for each location at a glance. ・ Congestion situation You can see how busy the Wi-Fi wireless channels are and easily see which channels are free. You can make Wi-Fi communication more comfortable by setting it to use a channel that is rarely used. ・ Speed measurement Measures internet download and upload speeds and Wi-Fi network speeds. The smaller the number, the slower, and the larger the number, the more comfortable. ・ Display of Wi-Fi information Displays various information (SSID, IP address, subnet mask, etc.) about the currently connected Wi-Fi. You can also open the router settings screen.
