Wifi doesn't work in Arch Linux

I put the latest Arch Linux on the laptop. Everything worked fine, but it does not work correctly to configure the adater to connect to WiFi. The standard actions didn't help. I assume that there are problems with the driver.

Ifconfig -a

Actually, ip a is in Arch, not ifconfig -a. Use NetworkManager it has nmcli and nmtui.
