How to install arch via WiFi?

Question

Arch Linux

Good afternoon.
There is no cable from the network at hand, but there is WiFi.
iwconfig showed that there is a wlan0 network.
ip link set wlan0 up
But, ip link shownothing came up.
Also, I connected via WiFi-menu, entered the password, but got an error.

iw dev wlan0 link
Not connected

Sorry for the screenshots from the phone, but I have no other choice, I hope for your help.
