Eu instalei recentemente o archlinux com o Gnome3 no meu Dell Inspiron 1520. Estou usando os drivers broadcom b43, já que o pcid da minha placa wifi é 14e4:4312
.
Quando eu instalei o NetworkManager (com chaveiro gnome) ele vê todas as conexões Wi-Fi disponíveis, mas sempre que clico em uma conexão criptografada ele primeiro pede Autenticação de Administrador (Na primeira tentativa), então continua desconectando e conectando automaticamente a primeira conexão não criptografada disponível.
Existe algo que eu não tenha instalado e / ou configurado?
Aqui está o log

Quando o nm-applet é iniciado, ele se registra no NetworkManager como um agente "secreto". Quando o NetworkManager precisa solicitar uma senha, ele pede ao agente para interagir com o usuário.
No entanto, não estava funcionando no meu sistema Arch:
$ pacman -Q network-manager-applet
network-manager-applet 0.9.8.0-1
Eu compilei o nm-applet do Git (nma-0-9-8 branch, commit 742e5daf91) e isso funcionou.
