+.Sh NAME
+.Nm iwx
+.Nd Intel 802.11a/b/g/n/ac/ax wireless network driver
+.Sh SYNOPSIS
+.Cd device iwx
+.Cd device wlan
+.Pp
+In
+.Xr rc.conf 5 :
+.Cd devmatch_blocklist="if_iwlwifi"
+.Cd kld_list="if_iwx"
+.Pp
+In
+.Xr sysctl.conf 5 :
+.Cd dev.iwx.?.debug=1
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for Intel Wireless AX series of M.2
+network adapters.
+.Pp
+These are the modes the
+.Nm
+driver can operate in:
+.Bl -tag -width "monitor mode"
+.It BSS mode
+Also known as
+.Em infrastructure
+mode, this is used when associating with an access point, through
+which all traffic passes.
+This mode is the default.
+.It monitor mode
+In this mode the driver is able to receive packets without
+associating with an access point.
+This disables the internal receive filter and enables the card to
+capture packets from networks which it wouldn't normally have access to,
+or to scan for access points.
+.El
+.Pp
+The
+.Nm
+driver can be configured to use
+Wired Equivalent Privacy (WEP) or
+Wi-Fi Protected Access (WPA1 and WPA2).
+WPA2 is currently the most secure encryption standard
+for wireless networks supported by
+.Fx .
+It is strongly recommended that neither WEP nor WPA1
+are used as the sole mechanism to secure wireless communication,
+due to serious weaknesses.
+WPA networks require use of
+.Xr wpa_supplicant 8 .
+The
+.Nm
+driver offloads both encryption and decryption of unicast data frames
+to the hardware for the CCMP cipher.
+.Pp
+In BSS mode the driver supports background scanning;
+see
+.Xr ifconfig 8 .
+.Pp
+The
+.Nm
+driver can be configured at runtime with
+.Xr ifconfig 8
+or at boot with
+.Xr rc.conf 5 .
+.Sh HARDWARE
+The
+.Nm
+driver provides support for the following M.2 wireless network adapters:
+.Bl -bullet -offset indent -compact

+Intel AX200
+.It
+Intel AX201 CNVi
+.It
+Intel AX210

+.Sh FILES
+The driver needs one of the following firmware files,
+which are loaded when an interface is brought up:
+.Pp
+.Bl -tag -width Ds -offset indent -compact

+.El
+.Pp
+These firmware files are not free because Intel refuses to grant
+distribution rights without contractual obligations.
+As a result, even though
+.Fx
+includes the driver, the firmware files cannot be included and
+users have to download these files on their own.
+.Pp
+A prepackaged version of the firmware can be installed using
+.Xr fwget 8 .
+.Sh DIAGNOSTICS
+.Bl -diag
+.It "iwx0: device timeout"
+A frame dispatched to the hardware for transmission did not complete
+in time.
+The driver will reset the hardware.
+This should not happen.
+.It "iwx0: fatal firmware error"
+For some reason, the firmware crashed.
+The driver will reset the hardware.
+This should not happen.
+.It "iwx0: radio is disabled by hardware switch"
+The radio transmitter is off and thus no packet can go out.
+The driver will reset the hardware.
+Make sure the laptop radio switch is on.
+.It "iwx0: could not read firmware ... (error N)"
+For some reason, the driver was unable to read the firmware image from
+the filesystem.
+The file might be missing or corrupted.
+.It "iwx0: firmware too short: N bytes"
+The firmware image is corrupted and can't be loaded into the adapter.
+.It "iwx0: could not load firmware"
+An attempt to load the firmware into the adapter failed.
+The driver will reset the hardware.

+.Sh HISTORY
+The
+.Nm
+device driver first appeared in
+.Ox 6.7
+and
+.Fx 15.0 .
+.Sh CAVEATS
+The
+.Nm
+driver does not support any of the 802.11ax capabilities offered
+by the adapters.
+Additional work is required in
+.Xr ieee80211 9
+before those features can be supported.
