Como posso ativar a conexão sem fio no Elementary OS?

Question

Após instalar o Elementary Loki 0.4.1 no meu novo laptop HP-15bs015dx, o wireless não estava funcionando, nenhum adaptador wifi foi sequer detectado. Eu então tive que instalar manualmente os drivers para o meu hardware, usando o repositório git rtlwifi_new de Larry Finger, via dkms.

Após a reinicialização, meu adaptador wi-fi é agora detectado, mas as configurações de rede me dizem "wireless está desabilitado; habilite wireless para descobrir pontos de acesso sem fio nas proximidades."
