osx - Is there an API or software to get accurate strength of a WiFi signals on Mac? -


is there api, shell command or applescript getting accurate reading of current wifi strength in mac osx?

fyi can open browser , use javascript if has value available.

what i'm trying check wifi strength different spots in kitchen or living room. need check wifi strength each spot. if it's low move new spot. wifi bars osx displays not enough data me.

there built-in airport command it. it's location is:

/system/library/privateframeworks/apple80211.framework/versions/current/resources/airport

for convenience, can create link let run command anywhere.

 sudo ln -s /system/library/privateframeworks/apple80211.framework/versions/current/resources/airport /usr/sbin/airport

to info current wireless network

airport -i

assuming you've created link, applescript converts value percentage , displays notification:

set wirelessrssi shell script "airport -i | grep ctlrssi | sed -e 's/^.*: //g'" set wirelessstrength (wirelessrssi + 100) * 2 display notification "wireless sigal quality: " & wirelessstrength & "%"
