You only need to copy the firmware you need for your wireless card. You don't need to copy all others.

If you cannot find your card's firmware, check OpenBSD's firmware:

http://firmware.openbsd.org/firmware/7.5/

For Intel Wireless AC 3168, it may be necessary to apply this patch:

diff 6b5d2ac468490a417e2dc36d13662b021d360200 uncommitted --- a/sys/src/9/port/etheriwl.c +++ b/sys/src/9/port/etheriwl.c @@ -4479,6 +4479,10 @@ family = 8000; fwname = "iwm-8000C-34"; break; + case 0x24fb: /* Wireless AC 3168 */ + family = 7000; + fwname = "iwm-3168-29"; + break; case 0x24fd: /* Wireless AC 8265 */ family = 8000; fwname = "iwm-8265-34";

Next, rebuild the kernel:

; cd /sys/src/9/pc64 ; mk install ; 9fs 9fat

(Optionally, you can rebuild the entire system: http://fqa.9front.org/fqa5.html)

Then, copy the kernel. For 386:

; cp /386/9pc /n/9fat/

For amd64:

; cp /amd64/9pc64 /n/9fat/

Reboot:

; fshalt -r

When you view /dev/kmesg, the device should appear:

#l0: rtl8169: 10Mbps port 0x3000 irq 255 ea c46516b43793 #l1: iwl: 54Mbps port 0xA6B00000 irq 255 ea 000000000000

On this machine, the second line is the wifi card, Intel Dual Band Wireless-AC 3168NGW Stone Peak.

Troubleshooting:

; ls '#l1' ls: #l1: no free devices

The device is not recognized.

In /dev/kmesg, you should see a line that resembles:

#l1: iwl: 54Mbps port 0xA6B00000 irq 255 ea 000000000000

It needs to match your device to indicate that it has been detected.

Connecting

Consult the ipconfig(8) and wpa(8) man pages.

status: associated

; bind -b '#l1' /net.alt ; bind -b '#I1' /net.alt ; aux/wpa -s YOURESSID -p /net.alt/ether1 ; ip/ipconfig -x /net.alt ether /net.alt/ether1

/net.alt/ether1/ifstats will show local access points

To test if it works:

; ip/ping /net.alt/icmp!8.8.8.8

Thanks to qwx on OFTC for helping with instructions and the patch!
