Como instalar o driver RTL8723AE no Ubuntu 16.04?

Question

Estou tentando configurar o Ubuntu 16.04 em um notebook MSI s12, mas o adaptador de rede (RTL8723AE Adaptador de Rede Wireless PCIe) não é reconhecido pelo Ubuntu.

$ iwconfig syas:

    lo        no wireless extensions.     
    enp2s0    no wireless extensions.

              Retry short limit:7   RTS thr=2347 B   Fragment thr:off
              Power Management:off

aqui estão os resultados de $ ifconfig :

O que eu já fiz?

Eu segui esta solução: link o que sugere:

sudo add-apt-repository ppa:hanipouspilot/rtlwifi
sudo apt-get update
sudo apt-get install rtlwifi-new-dkms linux-firmware

e este aqui: instale um driver mais recente que diz:

wget https://github.com/lwfinger/rtlwifi_new/archive/rock.new_btcoex.zip
unzip rock.new_btcoex.zip
cd rtlwifi_new-rock.new_btcoex
make
sudo -i
make install
echo "options rtl8723be ant_sel=2"  >  /etc/modprobe.d/rtl8723be.conf
exit

Reboot.

Eu também instalei WICD conforme as instruções abaixo: Instalando o WICD . Mas não há nenhum adaptador sem fio funcionando .

Atualizações

1. Eu instalei o pacote bcmwl-kernel-source . 1.1. removido.
2. sudo modprobe wl && dmesg | grep wl retorna:

3. sudo lshw -C network

Answer 1

Torne o parâmetro permanente com o terminal:

sudo -i
echo "options rtl8723ae msi=1"  >  /etc/modprobe.d/rtl8723ae.conf
exit

Após a inicialização, você deve estar pronto.

    

Answer 2

O problema foi resolvido usando esta postagem :

1. Projeto clone: git clone [email protected]: lwfinger / rtlwifi_new.git
2. Construir projeto: make; sudo make install
3. Remove o antigo mod: sudo rmmod rtl8723ae
4. Defina o mod com o sinalizador msi: sudo modprobe rtl8723ae msi = 1
