First, download	the firmware:

; git/clone gits://git.9front.org/plan9front/firmware  ;  cp
firmware/* /lib/firmware/

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:

			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










			   - 2 -


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.

patch!
