QWX(4) Device Drivers Manual QWX(4)

qwxQualcomm IEEE 802.11a/ac/ax/b/g/n wireless network device

qwx* at pci?

The qwx driver provides support for Qualcomm Technologies QCNFA765 802.11ax devices.

The qwx driver can be configured at runtime with ifconfig(8) or on boot with hostname.if(5).

The driver needs the following firmware files, which are loaded when an interface is brought up:


These firmware files are not free because Qualcomm refuses to grant distribution rights without contractual obligations. As a result, even though OpenBSD includes the driver, the firmware files cannot be included and users have to download these files on their own.

A prepackaged version of the firmware can be installed using fw_update(8).

The following example scans for available networks:

# ifconfig qwx0 scan

The following hostname.if(5) example configures qwx0 to join network “mynwid”, using WPA key “mywpakey”, obtaining an IP address using DHCP:

join mynwid wpakey mywpakey
inet autoconf

arp(4), ifmedia(4), intro(4), netintro(4), pci(4), hostname.if(5), ifconfig(8)

The qwx driver first appeared in OpenBSD 7.5.
