我在使用 Ubuntu 20.04 的 Legion 530 上启用 Wi-Fi 时遇到了困难。
我到目前为止尝试过的事情
sudo tee /etc/modprobe.d/blacklist-ideapad.conf <<< "blacklist ideapad_laptop"
rebooted
我可以看到 Wi-Fi 已启用，但无法检测到任何可用的网络。
然后我尝试：
echo "options r8822be aspm=0" | sudo tee /etc/modprobe.d/r8822be.conf
sudo rmmod r8822be
rmmod: ERROR: Module r8822be is not currently loaded
我将非常感激您的帮助。

我甚至尝试过以下步骤，但没有任何效果
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
笔记：Ubuntu 18.04 上一切运行正常
答案1
我有一台联想 Ideapad 530S，从 Ubuntu 18.04 升级到 20.04 后，WI-FI 停止工作了。
这篇文章对我有帮助： https://askubuntu.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
答案2
我有一台联想 Ideapad，Ubuntu 20.04.03 LTS，内核为 5.11.0.27，使用 PCI Realtek 8822be Wi-Fi/蓝牙适配器。
我试过Bulat 的驱动程序修复以上，但长期来看并没有效果。最后我找到了一个帖子，建议转向离开使用此命令进行 Wi-Fi 电源控制：
sudo sed -i 's/3/2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
这招很管用。
