ワイヤレスネットワークがリストされていない[非表示のネットワーク]

Question

私のホームワイヤレスネットワークは非表示ネットワークとしてリストされており、ログインするたびに手動で接続する必要があります。ワイヤレス接続リストにリストされていません。 [非表示のワイヤレスネットワークに接続]オプションを選択してのみ接続できます。 12.04では問題ありませんでした。

私のラップトップモデルは次のとおりです。DellInspiron n5110

OS：12.10-64ビット

Answer 1

最初に、隠されたワイヤレスネットワークが通常のワイヤレス接続よりもさらに脆弱であることが判明したことを警告する必要があります。手動評価には理由があります。したがって、ルーターが非表示にならないように再構成することをお勧めします。

もちろん、隠れた接続の使用を主張する場合の迷惑な手動評価を避けるための回避策があります。 nm-connection-editorを開き、clear「すべてのユーザーが利用可能」のチェックボックスをオンにします。その後、ネットワークマネージャは自動接続できるはずです。

Answer 2

手動スキャンを実行すると、ネットワークSSIDが表示されますか？

1. ワイヤレスインターフェース名を確認してください

   iwconfig

出力は次のようになります

$ iwconfig

eth0      no wireless extensions.

wlan0     IEEE 802.11abg  ESSID:"..."  
          Mode:Managed  Frequency:... GHz  Access Point: ...

2. ネットワークをスキャンし、（wlan0をインターフェイス名に置き換えて）によって、確立されたSSIDのみを表示します。

   Sudo iw dev wlan0スキャン| grep SSID

出力は次のようになります

SSID: ed...
SSID: TUB...
SSID: ed...
...
