[DragonFlyBSD - Bug #2806] failed to configure a link-local address on ath0 (errno = 22)

[bugtracker-admin at leaf.dragonflybsd.org]

Issue #2806 has been updated by daftaupe.


For what it's worth after 6 years, I found a laptop with such a Wireless adapter : 

<pre>
ath0 at pci0:1:0:0:        class=0x028000 card=0x410e144d chip=0x0032168c rev=0x01 hdr=0x00
    vendor     = 'Qualcomm Atheros'
    device     = 'AR9485 Wireless Network Adapter'
    class      = network
</pre>

It's working out of the box with the 6.0-RELEASE, but not with 5GHz networks (that was my mistake at the beginning).

The working rc.conf configuration is :

<pre>
dhcpcd_enable="YES"
ifconfig_wlan0="WPA"
</pre>

And for /etc/wpa_supplicant.conf I had to add the following lines 

<pre>
network={
        ssid="mynetwork"
        scan_ssid=0
        psk="xxxx"
        priority=5
}
</pre>
