I want to install Artix, but I'm having some problems.

First, I tried using the community KDE ISO. Install went fine and dandy. But I couldn't do pacman -Syu because of conflicts with libjdk or some such.
I want to note that the Artix wiki says the ISOs are rebuilt every 2 weeks, but the most current ones are from last July. Are there more recent ISOs available?

So I tried doing it the hard way with the base install. I used the community ISO again to get the wireless working during the install, but when it gets to rebooting the laptop I don't have working wifi. This is on a Lenovo Thinkpad T480.

/etc/conf.d/net has

modules_wlan0="wpa_supplicant"
config_wlan0="dhcp"

/etc/wpa_supplicant/wpa_supplicant.conf has

country=us
update_config=1
ctrl_interface=/var/run/wpa_supplicant

network={
     scan_ssid=1
     ssid="<my wifi network>"
     psk="<wifi password>"
}

This fails on bootup with

Bringing up interface wland0
  Caching network module dependencies
  Starting wpa_supplicant on wlan0 ...
Successfully initialized wpa_supplicant
rfkill: WLAN soft blocked
rfkill: WLAN soft blocked
  dhcp ...
    running dhcpcd ...
dhcpcd-10.0.6 starting
dhcpcd_prestartinterface: Operation not possible due to RF-kill
wlan0: waiting for carrier

ERROR: net.wlan0 failed to start

Any ideas on what I'm doing wrong? Why is my wlan0 soft blocked?
