Ubuntu 20.04 Focal FossaのWifiの問題
したがって、18.04 LTSからこの新しいバージョンまでクリーンインストールを行いましたが、私はそれをとても気に入っていますが、通常はインストール用にイーサネットケーブルを接続しますが、切断すると、同じ問題が数年前にPop OSを使用していましたが、Realtek RTL8822BE WiFiカードを搭載したラップトップを持っていて、Bluetoothはうまく機能しますが、WiFiを有効にしてもネットワークが表示されません。
私はすでに試しましたSudo service network-manager動作しませんでした。追加のドライバに表示されないため、何らかのドライバがダウンロードされていることに気付きました
多分これは役立ちます：

私は何をすべきか手がかりがなく、フォーラムで見たすべてを試しましたが、何も修正されていません。誰かが私を助けてくれることを願っています！
とにかく、これはディストリビューションの問題だと思います。それは、それが真新しいことで、今日正式に発表されたばかりで、おそらくこのひどいカードを持っている人はあまりいないでしょう。
おかげで、
これは私が別のフォーラムで見つけた解決策です。他の人にとってはかなりうまくいったようです。私は同じ問題を抱えていないので、自分で試したことがありません。
ディレクトリを変更：
cd /lib/firmware
ディレクトリrtw88を作成
Sudo mkdir rtw88
作成したディレクトリにrtl8822befw.binをコピーします。
Sudo cp /lib/firmware/rtlwifi/rtl8822befw.bin /lib/firmware/rtw88/
そのファイルの名前をrtw8822b_fw.binに変更します。
Sudo mv /lib/firmware/rtw88/rtl8822befw.bin /lib/firmware/rtw88/rtw8822b_fw.bin
システムを再起動します
