Les conducteurs Realtek ne fonctionnent pas avec Ubuntu 20.04 noyau: 5.4

Je suis difficile pour activer le WiFi sur la Légion 530 avec Ubuntu 20.04.

Choses que j'ai essayées jusqu'à présent,

Sudo tee /etc/modprobe.d/blacklist-ideapad.conf <<< "blacklist ideapad_laptop"
rebooted

Je pouvais voir WiFi activé mais il n'a pas été capable de détecter des réseaux disponibles.

Puis j'ai essayé:

echo "options r8822be aspm=0" | Sudo tee /etc/modprobe.d/r8822be.conf
Sudo rmmod r8822be
rmmod: ERROR: Module r8822be is not currently loaded

J'apprécierais vraiment toute aide.

J'ai même essayé de suivre les étapes suivantes mais cela n'a fait aucune différence

git clone https://github.com/lwfinger/rtlwifi_new.git

cd rtlwifi_new
git checkout extended
make
Sudo make install
Sudo modprobe -r rtl8822be
Sudo modprobe rtl8822be

[~ # ~] note [~ # ~ ~]: Les choses fonctionnaient parfaitement sur Ubuntu 18.04

J'ai Lenovo Ideapad 530s, après la mise à niveau vers Ubuntu 20.04 à partir de 18.04 Wi-Fi a cessé de fonctionner.

Ce post m'a aidé: https://askabubuntu.com/a/1271087/972111

Sudo apt install build-essential git
git clone https://github.com/mid-kid/r8822be.git
cd r8822be
./make

# remove the misbehaving rtw88 module
Sudo rmmod rtwpci rtw88

# install the r8822be module
Sudo ./make install
Sudo modprobe r8822be
Sudo reboot
