Wi-Fiネットワークが検出されない

私はカリLinuxを使用しています。バージョン確認基準lsb_release -a

No LSB modules are available.
Distributor ID: Kali
Description:    Kali GNU/Linux Rolling
Release:    2021.1
Codename:   kali-rolling

ネットワークアダプタに問題があると思います。

の出力は ifconfig次のとおりです。

コマンドの出力はiwconfig次のとおりです。

ネットワークカード用のドライバをインストールしようとしています。ドライバのgithubディレクトリ 実行時に前提条件を完了した後

sudo ./dkms-install.sh  

出力は次のとおりです

About to run dkms install steps...
Error! DKMS tree already contains: rtl8821ce-v5.5.2_34066.20200325
You cannot add the same module/version combo more than once.

これは、ドライバがプリインストールされているがWi-Fiがまだ機能していないことを意味します。

どんな提案がありますか？
