新安装的笔记本电脑 rtl8821ce 中网络无人认领的 Wifi 不可用

我在笔记本电脑上安装了新的操作系统 debian bullseye。我在网络管理器中找不到 wifi 选项。

sudo lshw -C network给出，

将向后移植添加到源列表后，我运行

sudo apt install -t bullseye-backports firmware-realtek，然后就是表演了firmware-realtek is already the newest version (20210315-3)。

我可以看到RTL8821C无需向后移植即可使用这里。

的输出sudo modprobe wl && dmesg | grep wl是modprobe: FATAL: Module wl not found in directory /lib/modules/5.10.0-9-amd64

输出ifconfig

还sudo journalctl | grep rtw返回

并sudo dkms status没有返回任何内容。

我禁用了安全启动并重新安装了驱动程序。但没有奏效。

答案1

从安装驱动程序这个 git 存储库。正如托马斯皮尼奥所说：

Wi-Fi 不适用于内核 >= 5.9

Linux Kernel 5.9 版本附带了由 Realtek 开发的损坏的 rtw88 模块，该模块与大多数版本的 8821ce 芯片兼容性较差。

sudo apt install git bc module-assistant build-essential dkms
sudo m-a prepare
echo "blacklist rtw88_8821ce" |sudo tee -a /etc/modprobe.d/blacklist.conf
git clone https://github.com/tomaspinho/rtl8821ce.git
cd rtl8821ce
sudo ./dkms-install.sh

答案2

如果您对此感到抓狂，并且这是一个选项，最新的 Ubuntu 22.04.1 可以与 RTL8821CE 一起使用。甚至不需要单击“启用专有”框。从 USB 启动后甚至在安装之前它就可以工作。

我更喜欢 Debian，在我的主机上安装它，因为它比 Ubuntu 更严格的自由开源软件。在这种情况下，虽然这并不重要，但我花了几个小时尝试 Debian 非自由的解决方案，从https://github.com/tomaspinho/rtl8821ce和来自https://github.com/lwfinger/rtw88在 Debian 11 Bullseye 上的所有情况下，它都没有丝毫承认 RTL8821CE 的存在。

公认的解决方案可能有效，但我可能错过了一些微妙之处。搜索结果显示 Debian 上的 WiFi 卡存在很多问题。下次我想在 Realtek 或 HP PC 上安装 Linux 时，我会三思而后行，但希望 Debian 能够及时支持它，而不会出现太多戏剧性的情况。

答案3

尝试

echo "options 8821ce wapf=1" | sudo tee /etc/modprobe.d/8821ce.conf

并重新启动
