wpa_supplicant-0.7.3

The WIFI server terminal program Wpa_supplicant contains two main executable tools:

Wpa_supplicant and WPA_CLI.

Wpa_supplicant is the core program,

Its relationship with WPA_CLI is the relationship between service and client: Run Wpa_supplicant in the background, use WPA_CLI to search, set up, and connect to the network.
