私は古いDellノートブック（Latitude D800）でBroadcom 4306/2を使用しようとしてきました。
私の状況は非常に近いです。これ
上記の解決策はb43legacyを削除し、代わりにb43を使用するようです。文書はb43legacyが正しいことを明確に示しています。とにかく、それらのどれも私のために働かなかった。
Debian Squeezeを実行していますが、いくつかのArchページをガイドとして使用しました。これは、Archの作者が一般的に低いレベルで書くので、何が間違っているかをよりよく理解できるからです。
これデバッグ方法としてこれ無線インタフェースの設定方法について説明します。
私にとっては、ハードウェアが動作し、ソフトウェアがハードウェアと話しているようです。以下のwpa_supplicant出力を参照してください。チップがAPの正しいSSIDを検出するので、無線が機能します。しかし、相関することはできません。
また、b43legacyのlsmodとmodinfoの出力も表示されます。この記事を読む方法を知っている人が助けてくれたらとても感謝します。どのように進むべきかわかりません。
