16.04アップグレード後にWifiが機能しない
Asus 1015E-DS02 があります
私は解決策を試しました こちら 無駄に。
私のwifiはアップグレード以来まったく機能していませんでしたが、 here および here のソリューションも試しました。
また、12.04から14.04にアップグレードした直後に、16.04にアップグレードしたことに注意してください。 Wi-Fiが14.04で動作したことはほぼ確実です。
「このデバイスはalterateドライバーを使用していますか？」
これはすべて1つのスクリプトで の結果です。

EDIT：フォローした後 このフォーラムlspci -vnn -d 14e4:がCapabilities: <access denied>を与えることに気付きました。提案された/var/lib/dkms/broadcom-wl/を探したとき、それは存在しませんでした。私はそれが何を意味するのか分からないが、多分重要だと感じる。
EDIT：ソリューション here も機能しませんでした。
EDIT：私の友人はそれを見て、それがUEFIの問題に関連している可能性があると考えています。
最初に、正しいカーネルをインストールする必要があります
Sudo apt install linux-generic
次に、間違ったドライバーを削除します
Sudo apt purge bcmwl-kernel-source
再起動後、すべてが機能するはずです。
