estoy usando unTP-Link AV-500Kit adaptador de línea eléctrica para proporcionar un AP inalámbrico en una parte de mi casa. Se conecta a través de las líneas eléctricas a mi enrutador principal. Sin embargo, mi computadora portátil, que ejecuta Arch Linux de 64 bits, no puede conectarse.
Otros dispositivos (un teléfono Android, un iPhone, una tableta Android) pueden conectarse sin problemas. El portátil puede conectarse perfectamente al router y a otros puntos de acceso (incluida una red de 5Ghz), pero aunque ve el punto de acceso TP-Link, no puede conectarse a él. Aquí está la sección relevante de dmesg:

He desactivado la seguridad en TP-Link por lo que no es un problema de autenticación. Está configurado en modo "11bgn mixto":

También probé el wlcontrolador:
$ sudo modprobe -r brcmsmac
$ sudo modprobe wl
$ sudo modprobe lib80211
Eso tampoco se puede conectar pero da un error diferente:

Siguiendo la sugerencia de GAD3R, intenté deshabilitar IPv6 agregando ipv6.disable=1a la optionslínea en /boot/loader/entries/arch.conf, comentando cualquier línea de IPv6 /etc/hostsy reiniciando. Ninguna diferencia.
¿Cómo puedo conectar esta máquina a esta red?
