.Dd $Mdocdate: May 29 2024 $ .Dt QWX 4 .Os .Sh NAME .Nm qwx .Nd Qualcomm IEEE 802.11a/ac/ax/b/g/n wireless network device .Sh SYNOPSIS .Cd "qwx* at pci?" .Sh DESCRIPTION The .Nm driver provides support for Qualcomm Technologies QCNFA765 802.11ax devices.

p The .Nm driver can be configured at runtime with .Xr ifconfig 8 or on boot with .Xr hostname.if 5 . .Sh FILES The driver needs the following firmware files, which are loaded when an interface is brought up:

p l -tag -width Ds -offset indent -compact t Pa /etc/firmware/qwx-wcn6855-hw2.0-amss t Pa /etc/firmware/qwx-wcn6855-hw2.0-board-2 t Pa /etc/firmware/qwx-wcn6855-hw2.0-m3 t Pa /etc/firmware/qwx-wcn6855-hw2.0-regdb t Pa /etc/firmware/qwx-wcn6855-hw2.1-amss t Pa /etc/firmware/qwx-wcn6855-hw2.1-board-2 t Pa /etc/firmware/qwx-wcn6855-hw2.1-m3 t Pa /etc/firmware/qwx-wcn6855-hw2.1-regdb .El

p These firmware files are not free because Qualcomm 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 download these files on their own.

p A prepackaged version of the firmware can be installed using .Xr fw_update 8 . .Sh EXAMPLES The following example scans for available networks:

p .Dl # ifconfig qwx0 scan

p The following .Xr hostname.if 5 example configures qwx0 to join network .Dq mynwid , using WPA key .Dq mywpakey , obtaining an IP address using DHCP: d -literal -offset indent join mynwid wpakey mywpakey inet autoconf .Ed .Sh SEE ALSO .Xr arp 4 , .Xr ifmedia 4 , .Xr intro 4 , .Xr netintro 4 , .Xr pci 4 , .Xr hostname.if 5 , .Xr ifconfig 8 .Sh HISTORY The .Nm driver first appeared in .Ox 7.5 . .Sh CAVEATS The .Nm driver does not support any of the 802.11n, 802.11ac, and 802.11ax capabilities offered by the hardware. .Sh BUGS Broadcast and Multicast frames are only received on networks which do not use encryption or which use WPA2 with group cipher CCMP. This prevents ARP and IPv6 from working correctly on other types of networks.
