what does "no avail" mean? The iwd package and starting it's service should give you iwctl like on the ISO.
I noticed that networkctl is available. I've removed iwd, wireless_tools, wpa_supplicant; and have enabled systemd-networkd service. However I don't know how to use networkctl to configure wifi.
I liked iwctl when installing arch, however when I lauched iwctl post-install, it would output a message 'starting iwd' or something and hang forver.
I later installed 'wireless-tools wpa_supplicant dialog'. I can see iwconfig display the interfaces, and iwlist <interface> show wireless networks. I just don't know how to connect.
Thanks.
