El wifi no esta funcionando

Antes al menos se conectaba pero no escaneaba nuevas redes. Ahora ni escanea nuevas redes ni se conecta. En el live boot con el usb si escanea y se puede conectar normal.

Con tan poca información es complicado poder deducir que estará pasando. Aquí te dice cómo proporcionar información de tu sistema:

Como mínimo un inxi -v7azy a ver qué tarjeta de red es.

Despues de reiniciar el wifi volvio a funcionar normalmente. Mi laptop tiene un dual boot y cuando ingresé a windows y volví a manjaro otra vez dejó de funcionar el wifi.

Tarjeta de red con chip Mediatek MT7922, parece que no eres el único con problemas con ese chip. En este hilo comentan que les sucede lo mismo y que es un problema con una actualización del firmware. Al final hay un enlace con una página de Github donde descargar e instalar el firmware corregido.

Lo hice y sigue sin funcionar
