问题与此相同：
从 5.15.0-60 升级到 5.19.0-32 后 RTL8821CE wifi 失败

07:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. RTL8411 PCI Express Card Reader (rev 01)
07:00.2 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 0a)
08:00.0 Network controller: Broadcom Inc. and subsidiaries BCM4313 802.11bgn Wireless Network Adapter (rev 01)
我被建议安装 Broadcom 驱动程序，我确实使用了
sudo apt install firmware-b43-installer
驱动程序现在显示在软件和更新中，但重启后我仍然看不到 WiFi 选项。
