WLAN funktioniert nicht unter Ubuntu 16.04, RTL8723DE

Ich habe einen HP-Laptop mit Dual-Boot, mit Ubuntu 16.04 und Windows 10. Während WLAN unter Windows 10 einwandfrei funktioniert, ist die WLAN-Option unter Ubuntu nicht verfügbar. Ich habe Secure Boot deaktiviert und verschiedene in diesem Forum angebotene Lösungen ausprobiert. Keine hat funktioniert.

Die Ausgabe sudo iwlist scanlautet:

eno1      Interface doesn't support scanning.

Antwort1

Öffnen Sie mit einer vorübergehend funktionierenden Internetverbindung über Ethernet, Tethering oder auf eine andere mögliche Weise ein Terminal und führen Sie folgende Schritte aus:

sudo apt update
sudo apt install build-essential dkms git
git clone -b 4.10-down https://github.com/jeremyb31/rtl8723de.git
sudo dkms add ./rtl8723de
sudo dkms build rtl8723de/5.1.1.8_21285.20171026_COEX20170111-1414
sudo dkms install rtl8723de/5.1.1.8_21285.20171026_COEX20170111-1414
sudo modprobe 8723de

Ihr WLAN sollte jetzt funktionieren.
