Inicialmente sem fio não funcionava - ele encontrava a rede sem fio e começava a se conectar, mas continuava solicitando a senha e nunca conectava.
Eu encontrei esta correção proposta no LinuxMint.com que instala uma versão mais antiga do microcódigo (firmware) para meu dispositivo.
Isso parece ter desativado qualquer recurso sem fio. rfkill list all não mostra nada e não há nenhuma opção sem fio na minha 'barra de tarefas'.
Sou um novato em Linux, então fique por dentro de mim e deixe-me saber se posso adicionar saídas de comando que possam ajudá-lo a resolver esse problema! :)

Sugiro que tente isso:
sudo su
mv /lib/firmware/iwlwifi-1000-5.ucode.backup /lib/firmware/iwlwifi-1000-5.ucode
echo "options iwlwifi 11n_disable=1 bt_coex_active=N" > /etc/modprobe.d/iwlwifi.conf
exit
Reinicie e informe se o seu dispositivo sem fio está funcionando como esperado.
