最近、ワイヤレスインターネットを利用するために新しいデスクトップコンピュータを購入し、USBワイヤレスアダプタも購入しました。選ぶことにしましたこのモデル過去には、排他的なドライバのためにほとんどのワイヤレスカードに問題があったからです。インターネットを「すぐに利用可能」にするのは良いことですが、まだ正しく機能していません。
私はしばらくインターネットを閲覧し、次のオプションを試しましたが、成功しませんでした。
- インストールされたファームウェア-atheros
- アダプタを別のUSBスロットに接続してみてください（わかりませんが…）
今朝はろうそくをつけてください。

ドキュメントから：Penguin Wireless N USBアダプター（TPE-N150USB）GNU / Linux用のDebianファームウェアのインストール
アダプタでDebian 7（Wheezy）、Debian 8（Jessie）、またはDebian 9（Stretch）を使用するには：カーネルをアップグレードする必要はありません。ファームウェアをコンピュータにコピーするだけです。
/lib/firmware
rootユーザーとして：
cd /lib/firmware
wget https://www.thinkpenguin.com/files/ath9k_firmware_free-version/htc_9271.fw
wget https://www.thinkpenguin.com/files/ath9k_firmware_free-version/htc_7010.fw
reboot
また参考にしてください：Debian 9（Stretch）を使用していてアクセスポイントのリストが表示されているが接続できない場合は、次のことを試してください。
sudo nano /etc/NetworkManager/NetworkManager.conf
次の行を追加します。
[device]
wifi.scan-rand-mac-address=0
その後、ネットワーク管理者を再起動します。
sudo service network-manager restart
