Estou usando o laptop dell inspiron 15 5570. Eu tenho windows10 e ubuntu 14.04LTS (dual os). Wifi não está conectado automaticamente, habilitar a opção Wifi não está listado ao clicar no ícone do wifi. No Windows 10, o Wi-Fi é conectado automaticamente e funciona bem.
Se eu conectar o dongle wifi, os wifi disponíveis estão listados e consigo me conectar. Mas se eu remover dongle wi-fi, listados nomes wi-fi e ativar a opção wifi não é mostrado na lista. Eu instalei broadcam e b43 driver.Mas isso não ajuda.
Minha saída de terminal para o comando.

Você precisa de firmware! Com uma conexão de internet ativa, abra um terminal e faça:
cd /tmp
sudo wget http://security.ubuntu.com/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.169.1_all.deb
sudo dpkg -i linux*.deb
Reinicie e seu wireless deve estar funcionando.
