質問: シスコのワイヤレスアクセスポイントに接続できないのはなぜですか? dell inspiron 600mでlucid netbook remixを実行していますが、昨日、マウンテンビューのhacker dojoでワイヤレスネットワークに接続できませんでした。ネットワークには、ms、mac、linuxボックスなど、他にもたくさんの人がいましたが、私のラップトップにはipアドレスが割り当てられませんでした。オープンなホームネットワークに接続できます。wpaを使用するコーヒーショップでの接続に問題はありませんでした。 hacker dojoが実行中wpaで、パスワードを何度も確認しましたが、何の反応もありませんでした。どんなアイデアでも大歓迎です。追加情報:$iwlist eth1 scan eth1 scan completed : cell 01 - address: ec:c8:82:fa:63:92 essid:"hackerdojo-gwifi" protocol:ieee 802.11g mode:master frequency:2.412 ghz (channel 1) encryption key:on bit rates:1 mb/s;
