If the AP is using 47 WEP encryption, wep keys can be specified in the command. 48 Note: Every time before connecting to an AP scan command (iw dev mlan0 scan) should be used by user. 49 50iw dev mlan0 disconnect 51 This command will be used to disconnect from an AP. 52 53 54iw dev mlan0 ibss join <SSID> <freq in MHz> [fixed-freq] [fixed-bssid] [key 0:abcde] 55 The command will be used to join or create an ibss. Optionally, operating frequency, 56 bssid and the security related parameters can be specified while joining/creating 57 and ibss. 58 59iw dev mlan0 ibss leave 60 The command will be used to leave an ibss network. 61 62iw dev mlan0 link 63 The command will be used to get the connection status. The command will return parameters 64 such as SSID, operating frequency, rx/tx packets, signal strength, tx bitrate. 65 66 Apart from the iw utility all standard configurations using the 'iwconfig' utility are also supported. 67 68 b) Debugfs interface 69 70 The debugfs interface can be used for configurations and for getting 71 some useful information from the driver. 72 The section below explains the configurations that can be 73 done. 74 75 Mount debugfs to /debugfs mount point: 76 77 mkdir /debugfs 78 mount -t debugfs debugfs /debugfs 79 80 The information is provided in /debugfs/mwifiex/mlanX/: 81 82iw reg set <country code> 83 The command will be used to change the regulatory domain. 84 85iw reg get 86 The command will be used to get current regulatory domain. 87
