If the AP is using + WEP encryption, wep keys can be specified in the command. + Note: Every time before connecting to an AP scan command (iw dev mlan0 scan) should be used by user. + +iw dev mlan0 disconnect + This command will be used to disconnect from an AP. + + +iw dev mlan0 ibss join <SSID> <freq in MHz> [fixed-freq] [fixed-bssid] [key 0:abcde] + The command will be used to join or create an ibss.
