.Sh NAME
.Nm ipw
.Nd
.Tn Intel
PRO/Wireless 2100 IEEE 802.11B wireless network adapter
.Sh SYNOPSIS
.Cd "ipw* at pci?"
.Sh DESCRIPTION
The
.Nm
driver provides support for the
.Tn Intel
PRO/Wireless 2100 MiniPCI network
adapter.
.Pp
By default, the
.Nm
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 FILES
The driver needs some firmware files,
which are loaded on demand when the device is attached:
.Pp
.Bl -tag -width Ds -offset indent -compact
.It Pa /etc/firmware/ipw-license
.It Pa /etc/firmware/ipw-bss
.It Pa /etc/firmware/ipw-ibss
.It Pa /etc/firmware/ipw-monitor
.El
.Pp
These firmware files are not free because Intel refuses to grant
distribution rights without contractual obligations.
As a result, even though
.Ox
includes the driver, the firmware files cannot be included and
users have to find these files on their own.
The official person to state your views to about this issue is
peter.engelbrecht@intel.com at (858) 391 1857.
.Sh EXAMPLES
Join an existing BSS network (ie: connect to an access point):
.Pp
.Dl "# ifconfig ipw0 inet 192.168.0.20 netmask 0xffffff00"
.Pp
Join a specific BSS network with network name
.Dq Li my_net :
.Pp
.Dl "# ifconfig ipw0 inet 192.168.0.20 netmask 0xffffff00 nwid my_net"
.Pp
Join a specific BSS network with 64 bits WEP encryption:
.Bd -literal -offset indent
# ifconfig ipw0 inet 192.168.0.20 netmask 0xffffff00 nwid my_net \e
        nwkey 0x1234567890
.Ed
.Pp
Join a specific BSS network with 128bits WEP encryption:
.Bd -literal -offset indent
# ifconfig ipw0 inet 192.168.0.20 netmask 0xffffff00 nwid my_net \e
        nwkey 0x01020304050607080910111213
.Ed
.Sh DIAGNOSTICS
.Bl -diag
.It "ipw%d: device timeout"
The driver will reset the hardware.
This should not happen.
