无线芯片组 RTL8821CE 未被认领，且未在 ifconfig 中显示

我一直试图将我的内部无线适配器连接到 ubuntu 20.04.3 LTS，但没有成功。我下载了驱动程序，Software & Updates但运行时lshw -C network出现：

  *-network UNCLAIMED       
       description: Network controller
       product: RTL8821CE 802.11ac PCIe Wireless Network Adapter

       configuration: latency=0
       resources: ioport:e000(size=256) memory:a1100000-a110ffff

运行lspci表明它在那里：

02:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8821CE 802.11ac PCIe Wireless Network Adapter

但它没有出现在ifconfig：

它只显示环回和我在这里连接的无线适配器加密狗是我的 ubuntu 版本：
