Intel Wireless-N 2230またはASUS USBドングルを使用してネットワークに接続できない
現在、Ubuntu 15.05を実行しています。
Intel Corporation Centrino Wireless-N 2230：
Intel WifiでMSI moboを使用しています：
~ % lspci | grep Centrino

ただし、Ubuntuでは機能しません（Antergos Live USBで機能します）。ネットワークに接続できません。

ASUSTek Computer、Inc. USB-N13 802.11nネットワークアダプター：
そこで、Linuxサポートを宣伝する豪華なASUS n-13 USBドングルを購入しました（40ドル）。 2012年からですので、2015 Ubuntuでも動作するはずです。

これらの問題の解決方法を知っている人がいれば、助けてください。
ありがとう
ログファイルを掘り下げてみると、2つの可能性があります。
1）ルーターはUbuntuにIPアドレスを割り当てていません。これを以前に経験したことがありますが、同じマシンで、別のディストリビューションではなく別のディストリビューションで動作します。問題を解決した静的IPを割り当てることになりました。
または
2）上記の他の誰かが指摘しているように、14.04.3 LTSのlive distroリリースを試しましたか？これが動作し（古いカーネル）、Antergosが動作している（超新しいカーネル）場合、問題はカーネルにあると思われます。繰り返しますが、再インストールを提案するのではなく、原因を絞り込む必要があるかもしれないことを指摘しています。これが私たちのやり方です。
私の腸は、これがほぼ間違いなく15.04であり、バグのあるリリースであることを示しています。 14.04.3 LTSをテストします-テストのためだけです。
それが失敗した場合、サポートのために新しいカーネルが必要です。
それが機能する場合、私のお金はバグがある15.04リリースのカーネルにあります。解決策は、別のカーネルでロールフォワードまたはバックワードすることです。
これらのいずれも機能していない場合、割り当てられたIPアドレスについて説明します。私の2セント。
