e1000eドライバを使用すると、イーサネットの速度が非常に遅くなります。 - Slackware64

未使用のThinkPadにSlackware64をインストールしましたが、イーサネットを使用する場合は、ネットワーク速度を除いてすべてが正常です。最高速度は約50KB / sで、WiFiを使用するときに使用している間2MB / sを取得します。 Intel e1000eドライバがインストールされました(自動的に)ので、ドライバの選択とは何の関係もありません。 ThinkPadの特定のネットワークカードが何であるかはわかりませんが、次のいずれかでなければなりません。

  • インテル(R)82566MC
  • インテル(R)82566MM
  • インテル(R) PRO/1000PL

このカードにはe1000eドライバが合っているようです(?)。どうやって解決しますか?
