Я только переустановил Archlinux, решил попробовать KDE (plasma-desktop), и честно говоря первый раз столкнулся с таким (???). Каждый раз после перезагрузки, пропадает WLAN.

Legend: LOAD → Reflects whether the unit definition was properly loaded.
ACTIVE → The high-level unit activation state, i.e. generalization of SUB.
SUB → The low-level unit activation state, values depend on unit type.
31 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.
