私はaskubuntuから得たいくつかの方法を試しましたが、問題は持続します。
#sudo dkms install rtlwifi-new/0.6

それでもこのエラーが発生します！どうすればいいですか？
カーネルを 5.3 にアップデートすると、ログイン画面が表示される前にロードが中断されました。
CentOS 7.7を使用しています。
これはログファイルです。私はこの記事を読んでから何も理解していませんでした。私は初心者です。

もしそのrtlwifi-newドライバーこれ、カーネルバージョン4.2以降でのみサポートされています。
CentOSのデフォルトカーネル（バージョン3.10.x）（多くのバックポートされたパッチを含む）で使用しようとしているので、このドライバパッケージはそのカーネルに比べて新すぎます。 Ubuntuでは問題ありませんが、CentOS 7.xではそうではありません。
基本CentOS 7.7システムで最先端の5.3カーネルを実行しようとすると、いくつかの欠陥があることがわかります。このカーネルの辞書パッケージのバージョンをどこかから入手しましたか？それともソースから直接コンパイルしましたか？
ELRepoパッケージリポジトリには、CentOS 7.xで利用可能な事前パッケージされた5.3カーネルがあります。https://computingforgeeks.com/install-linux-kernel-5-on-centos-7/
独自の5.3カーネルをコンパイルした場合、ハードウェア機能にとって重要なドライバの一部がカーネル構成で選択されていないことを意味する可能性があります。
