答案1

第一个黑名单 rtw88_pci & rtw88_core

echo -e "blacklist rtw88_pci\n blacklist rtw88_core" | sudo tee /etc/modprobe.d/ blaclist_rtw88.conf

使用以太网或 USB 网络共享功能从官方来源安装替代驱动程序包。您不需要任何来自 github 的源代码。

sudo apt install rtl8821ce-dkms

重新启动检查

lsmod | egrep 'cfg80|mac80'
iwconfig
iwlist chan
nmcli dev wifi list

Wifi 已连接且已开启?尝试连接。

答案2

这个帖子包含安装您的 wifi 适配器驱动程序的指南。

以下是主要步骤的总结:

安装所需的软件包

sudo apt update
sudo apt install git build-essential dkms

从 GitHub 下载驱动程序并运行安装脚本:

git clone https://github.com/tomaspinho/rtl8821ce
cd rtl8821ce
chmod +x dkms-install.sh
sudo ./dkms-install.sh

重新启动系统,wifi 就可以正常工作了。

如果由于某种原因需要卸载它,请返回该目录并运行:

chmod +x dkms-remove.sh
sudo ./dkms-remove.sh
