NSS: NSS is an acronym and stands for Number of Spatial Streams.MCS index: The MCS index is an indicator of which protocols are used to encrypt the radio signal.PHY mode: This is the radio protocol that the router uses according to the radio standard.Tx rate: The transfer rate is the speed of data being transferred between your router and your computer.It is defined as the ratio of signal power to noise power and is usually given in decibels. SNR is a technical measure that compares the level of the desired signal to background noise. interfering signal: The signal-to-noise ratio (SNR) provides information about how badly the RSSI signal is affected by radio interference.With this information you can determine whether you have sufficient signal strength for a stable WiFi connection. RSSI: The Received Signal Strength Indicator (RSSI) provides information about how strong the router's signal is being received by your device.Channel: Your router's WiFi channel determines the frequency on which it transmits data.BSSID: Your router's MAC or hardware address is a unique identifier that allows it to communicate with other devices on the network.Safety: Most routers have WPA2 Personal as a security measure to encrypt and protect your network.Router: With the IP address of your router you can use your Browser access the web interface.IP address: Here you can see the IP address of your computer.With the option key (⌥) and a click on the WiFi symbol in the menu bar, you can see data about the current WiFi connection.

This will bring up additional data in the drop-down menu, providing information about the Wi-Fi network you're currently connected to. Check wifi speed To check the quality of Wi-Fi reception on Mac, just hold the option button (also 'ALT' or 'Option') on your keyboard while clicking the Wi-Fi icon in the upper-right corner of the menu bar. At first I thought you had to use a special tool on the Mac for this, but luckily macOS already has a function built in that allows you to see the current Wifi transmission rate with one click. If the WiFi on your Mac is sub-par and you're experiencing intermittent dropouts, it's important to test the practical speed of the WiFi signal between the router and the Mac.
