How can I install wpa_cli on my rooted device? I rooted my device, then I go to adb shell and type su to enter wpa_cli. I was surprised that wpa_cli: not found appeared, although I get information when I type wpa_supplicant.

I know that wpa_cli is from same library wpa_supplicant .
Install the app: WiFi WPS WPA Tester or AndroDumpper..

It has the latest compiled wpa_cli binary..
You can get the binary from the app's data from /data/data, and you might push it to /system/bin/ or /su/bin/ or wherever you need..


Edit:

Instead, you can use the wpa_supplicant binary, which can be found in many devices by default, if that's enough to do what you want..

Or if you wish, you can compile wpa_cli from source.
