|
driver configures the adapter for BSS operation (aka infrastructure mode).
|
|
This mode requires the use of an access point.
|
|
.Pp
|
|
For more information on configuring this device, see
|
|
.Xr ifconfig 8 .
|
|
.Sh CONFIGURATION
|
|
The
|
|
.Nm
|
|
driver can be configured at runtime with
|
|
.Xr ifconfig 8
|
|
using the following parameters:
|
|
.Bl -tag -width Ds
|
|
.It Cm bssid Ar bssid
|
|
Set the desired BSSID.
|
|
.It Fl bssid
|
|

|
|
The interface will automatically select a BSSID in this mode, which is
|
|
the default.
|
|
.It Cm chan Ar n
|
|
Set the channel (radio frequency) to be used by the driver based on
|
|
the given channel ID
|
|
.Ar n .
|
|
.It Fl chan
|
|
Unset the desired channel to be used by the driver.
|
|
The driver will automatically select a channel in this mode, which is
|
|
the default.
|
|
.It Cm media Ar media
|
|
The
|
|
.Nm
|
|
driver supports the following

|
.Bl -tag -width autoselect -compact
|
|
.It Cm autoselect
|
|
Enable autoselection of the media type and options.
|
|
.El
|
|
.It Cm mediaopt Ar opts

The
|
|
.Ar id
|
|
can either be any text string up to 32 characters in length,
|
|
or a series of hexadecimal digits up to 64 digits.
|
|
An empty
|
|
.Ar id
|
|
string allows the interface to connect to any available access points.
|
|
By default the
|

|
|
driver uses an empty string.
|
|
Note that network ID is synonymous with Extended Service Set ID (ESSID).
|
|
.It Cm nwkey Ar key

|
|
and the four keys,
|
|
.Dq k1
|
|
through
|
|
.Dq k4 ,
|
|
are configured as WEP keys.
|
|
If a set of keys is specified, a comma
|
|
.Pq Sq \&,
|
|
within the key must be escaped with a backslash.
|
|
Note that if multiple keys are used, their order must be the same within
|
|
the network.
|
|
.Nm
|
|
is capable of using both 40-bit (5 characters or 10 hexadecimal digits)
|
|
or 104-bit (13 characters or 26 hexadecimal digits) keys.
|
|
.It Fl nwkey
|
|
Disable WEP encryption.
|
|
This is the default mode of operation.

|
|
.Bl -diag
|
|
.It "iwn%d: device timeout"
|
|

|
|
For some reason, the firmware crashed.
|
|
The driver will reset the hardware.
|
|
This should not happen.
|
|
.It "iwn%d: radio is disabled by hardware switch"
|
|

|
|
.It "iwn%d: could not read firmware"
|
|
The driver was unable to find the file with the proper firmware image.
