[ahmad-abuziad]

Scenario

• Enable WIFI
• Connect to WIFI
• Store the Local IP in file
• Watch WIFI connection
• Retry connect on failure
• If failed connect to another WIFI
• Store the new Local IP in file

Improvements

• Notify another service about the new IP
• Store available wifi's credentials in file and read it from there
• Config file that contains the ip, wifi, credentials, network card
• Use variables
• Check ethernet cards
• Create nmcli as a resource/function

Notes

• "nmcli radio wifi off" will produce an error because "Connect to WIFI" will try to connect but the wifi is off

Terminal Commands

• nmcli device wifi list
• nmcli device wifi connect "SSID" password ""
• nmcli device wifi connect "SSID" password "" ifname ""
• nmcli device
• nmcli connection show --active
