Instalei o Debian 9 stretch (área de trabalho GNOME) de 64 bits no meu PC. Meu adaptador sem fio USB (TP-LINK TL-WN722N) foi detectado automaticamente após a instalação do firmware da atheros:
apt-get install firmware-atheros
Mas não consigo me conectar a nenhuma estrutura sem fio, esteja eles protegidos com senha ou desprotegidos.
Liguei o meu USB. Foi detectado, enviou autenticação, foi autenticado, mas anulou imediatamente a autenticação. Desabilitar o IPV6 não resolveu meu problema. Aqui está o meu dmesg

Não tenho idéia do por que isso aconteceu, nem por que foi abortado várias vezes em uma tentativa.
