U S E R M A N U A L
|
|
|
|
1) FOR DRIVER INSTALL
|
|
|
|
a) Copy sd8787.bin to /lib/firmware/mrvl/ directory,
|
|
create the directory if it doesn't exist.
|
|
b) Install WLAN driver,
|
|
insmod mwifiex.ko
|
|
c) Uninstall WLAN driver,
|
|
ifconfig mlanX down
|
|
rmmod mwifiex
|
|
|
|
|
|
2) FOR DRIVER CONFIGURATION AND INFO
|
|
The configurations can be done either using the 'iw' user space
|
|
utility or debugfs.
|
|
|
|
a) 'iw' utility commands
|
|
|
|
Following are some useful iw commands:-
|
|
|
|
iw dev mlan0 scan
|
|
|
|
This command will trigger a scan.
|
|
The command will then display the scan table entries
|
|
|
|
iw dev mlan0 connect -w <SSID> [<freq in MHz>] [<bssid>] [key 0:abcde d:1123456789a]
|
|
The above command can be used to connect to an AP with a particular SSID.
|
|
Ap's operating frequency can be specified or even the bssid. 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. Optionally, operating frequency,
|
|
bssid and the security related parameters can be specified while joining/creating
|
|
and ibss.
|
|
|
|
iw dev mlan0 ibss leave
|
|
The command will be used to leave an ibss network.
|
|
|
|
iw dev mlan0 link
|
|
The command will be used to get the connection status. The command will return parameters
|
|
such as SSID, operating frequency, rx/tx packets, signal strength, tx bitrate.
|
|
|
|
Apart from the iw utility all standard configurations using the 'iwconfig' utility are also supported.
|
|
|
|
b) Debugfs interface
|
|
|
|
The debugfs interface can be used for configurations and for getting
|
|
some useful information from the driver.
|
|
The section below explains the configurations that can be
|
|
done.
|
|
|
|
Mount debugfs to /debugfs mount point:
|
|
|
|
mkdir /debugfs
|
|
mount -t debugfs debugfs /debugfs
|
|
|
|
The information is provided in /debugfs/mwifiex/mlanX/:
|
|
|
|
iw reg set <country code>
|
|
The command will be used to change the regulatory domain.
|
|
|
|
iw reg get
|
|
The command will be used to get current regulatory domain.
|
|
|
