O Arch não pode se conectar a uma rede sem fio específica

Question

Estou usando um poder TP-Link AV-500 kit de adaptador de linha para fornecer um AP sem fio em uma parte da minha casa. Ele conecta as linhas de energia ao meu roteador principal. Meu laptop, no entanto, que está executando o Arch Linux de 64 bits, não pode se conectar a ele.

Outros dispositivos (um telefone Android, um iPhone, um tablet Android) podem ser conectados sem problemas. O laptop pode se conectar perfeitamente ao roteador e a outros pontos de acesso (incluindo uma rede de 5 Ghz), mas, embora ele veja o ponto de acesso TP-Link, ele não pode se conectar a ele. Aqui está a seção relevante de dmesg :

Desativei a segurança no TP-Link, por isso não é um problema de autenticação. Está definido para o modo "11bgn mixed":

Minha NIC sem fio é:

Eu também tentei o driver wl :

$ sudo modprobe -r brcmsmac 
$ sudo modprobe wl
$ sudo modprobe lib80211

Isso também não pode ser conectado, mas apresenta um erro diferente:

[ 1077.281794] ERROR @wl_cfg80211_scan : WLC_SCAN error (-22)

Seguindo a sugestão do GAD3R, tentei desabilitar o IPv6 adicionando ipv6.disable=1 à linha options em /boot/loader/entries/arch.conf , comentando as linhas IPv6 de /etc/hosts e reinicializando. Nenhuma diferença

Como posso conectar esta máquina a esta rede?
