Wifi working on Dell XPS 15 2019 using iwlwifi with Killer AX1650x chipset and lagg0

I have got wifi working on my Dell XPS 15 2019 with the following chipset

Killer(R) Wi-Fi 6 AX1650x 160MHz Wireless Network Adapter (200NGW), REV=0x340

which is supported by Iwlwifi

and for extra brownie points i have got it working with the lagg0 failover device

Example 3. Failover Mode Between Ethernet and Wireless Interfaces
docs.freebsd.org

Chapter 34. Advanced Networking

Advanced networking in FreeBSD: basics of gateways and routes, CARP, how to configure multiple VLANs on FreeBSD, etc
docs.freebsd.org docs.freebsd.org

after i set everything up i unplugged my ethernet and it switched to wifi instantly

whats great about the lagg0 failover is you dont have to restart any services

im gobsmacked the wifi works

i have freebsd installed on a macbook air 2011 and macbook pro retina 2015
which use broadcom chips, i will have to see if i can get wifi working on those machines as well

probably not that would be pushing my luck
no luck

i have a usb alfa wifi card which i use with the macs
i wonder if i could set that card to be a fallback device

what you have to do is set the ethernet mac address to the wifi cards mac address
following the freehand book link above

Code: 
/etc/rc.conf

Code: 
# laggo
# ethernet mac address set to wifi mac address
ifconfig_ue0="ether 78:2b:46:ee:27:a3"
wlans_iwlwifi0="wlan0"
ifconfig_wlan0="WPA"
create_args_wlan0="country GB"
cloned_interfaces="lagg0 lo1"
ifconfig_lagg0="up laggproto failover laggport ue0 laggport wlan0 DHCP"

lo1 in cloned_interfaces is for my jail and not needed for the wifi
so if your not using a jail you can remove that

also you can use the lagg0 device in your pf config
so you dont have to edit you pf config change the int_if and restart pf

Code: 
/etc/pf.conf

int_if set to lagg0

Code: 
int_if="lagg0"

Firefox in a jail with nat also work with pf and wifi

Code: 
ifconfig

Code:

Click to expand...
The Alfa USB device I used with run(4) interface has hostAP and has good range. The RT2870 ones.

It is old and everything else I tried from them is unsupported.
(As far as Alfa AWUS036*** type boxes. These are much better than sticks with external antenna.)

It is a very specific buy. I wanted best USB Wireless and this is what I bought. 35-40 bucks it was not cheap nor expensive.
 
i managed to get the alfa card working with lagg0
so if i unplug the ethernet it switches to the alfa card

also if you boot up without the alfa wifi card plugged in the ethernet still works
