Acabei de instalar o Ubuntu 16.-04 em um laptop HP novo, aparentemente com uma interface Intel WiFi (WiFi / Bluetooth combinados).
Infelizmente, não vejo nada sobre o adaptador WiFi e o WiFi não funciona. Tudo o resto, incluindo Ethernet, funciona bem.
Alguém pode me ajudar com isso? Eu já tentei muitas abordagens diferentes a partir deste site, mas até agora sem sorte.

Você tem o kernel 4.4. Não suporta este adaptador Intel. Você provavelmente instalou o Ubuntu a partir do ISO 16.04 original.
Se você tiver uma conexão com a internet com fio (parece que você atualizou seu sistema), então instale o kernel HWE executando
sudo apt install linux-generic-hwe-16.04
e reinicie.
O adaptador sem fio deve funcionar.
Outra opção é baixar e instalar a versão 16.04.2 "point" (ou mais recente). Suporta este adaptador fora da caixa.
Abra o terminal e digite:
sudo tee /etc/modprobe.d/rtl8723be.conf <<< "options rtl8723be ant_sel=1"
E reinicie!
Se o problema ainda não estiver resolvido, tente alterá-lo para ant_sel=2 .
