HP 15 AC179TX - WiFi não funciona após a instalação do Ubuntu

1

Instalei o Ubuntu 14.04.4 LTS no meu novo laptop HP 15 AC179TX. Não consegui ver nenhuma rede WiFi detectada. Eu poderia ver a opção "Ativar WiFi". Mas depois de ligar também nenhuma rede está sendo descoberta. No meu outro laptop eu pude ver o próximo por todas as redes.

Mais uma coisa interessante é a rede WiFi do hotspot móvel ser descoberta. Apenas os sinais WiFi do roteador não são descobertos. Isso é estranho, mas é isso que acontece.

Por favor, me ajude a corrigi-lo.

Abaixo estão as informações sem fio coletadas do sistema.
