If you’re trying to tweak a wireless router to get the best signal, it’s important to be able to continuously measure the Wi-Fi signal strength while you play with the antennas, placement, and everything else on the network. While most users are best served by using the Mac Wi-Fi Diagnostics app to check signal strength and performance, another option is to go to Mac OS X command line. We’re going to get here to treat. ..
This trick is a command line tool that can be used to connect to an airport Wi-Fi network. This tool is available on all Macs running all versions of Mac OS X.
Open the Terminal app and type: sudo apt-get update sudo apt-get install python3 python3-pip python3-requests
How to Check the Wi-Fi signal strength from the command line on Mac OS X and view the RSSI history
netstat -an | grep running To see a list of running processes, use the following command: netstat -a | grep process
While x is 1, do: /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport -I | grep CtlRSSI Sleep 0.5 ..
Hit return and you’ll see something like the following scrolling on the screen: You will see a list of options, each with a different color. The first option is blue, the second is green, and so on. The colors are based on how many times you have hit return.
This indicator tells you how strong your Wi-Fi signal is coming from the router. It will change frequently, as the number printed repeatedly on your screen.
If you want to stop the refresh of this continuous signal monitoring command, press Control + C in the Terminal window. ..
How to Test and view the Wi-Fi signal strength on a single line in Mac OS X Terminal
command report -s signal strength
Apple80211 is a privateFrameworks that enables Airports to communicate with each other. The -I flag tells Airports to search for resources in the /privateFrameworks/Apple80211.framework/Versions/Current directory. The grep CtlRSSI command finds RSSI values and prints them out. The sed -e ‘s /^.*: // g’ command makes the RSSI values more human-readable. Finally, xargs -I SIGNAL printf “rRSSI dBm: SIGNAL”; sleep 0.5; prints the RSSI values out to the console.
Press Control + C to stop the command. ..
Wi-Fi signals can be affected by many factors, including the strength of the wireless router’s antenna, interference from local items and physical barriers such as a chimney or microwave. To get the best Wi-Fi signal, make sure you choose a channel with minimal interference and check to see if your router is in a good location. ..
This command line approach works in all vaguely modern versions of Mac system software, and it’s also still present in the latest releases, including macOS Mojave, Catalina, Sierra, El Capitan, Mac OS X Mavericks, and others.
