在大多數情況下，我的無線網路運作得很好。但大約每天一次，我會隨機斷開連接，並彈出無線密鑰環身份驗證。所有正確的資訊都輸入到密鑰環中，但是當我點擊連接時，重新連接到網路失敗，並且再次彈出身份驗證視窗。網路正常運作，這是唯一受影響的電腦。透過重新啟動我的計算機可以解決此問題，但它是一台生產計算機，因此必須停止我正在處理的工作並重新啟動變得非常令人沮喪。
這是彈出的螢幕：
無線網卡是 D-link Xtreme N DWA-552

請幫忙！
更新：VLC 似乎使這個問題更加頻繁。在正常情況下，這種情況每天只發生一次，但是當我昨天運行 VLC 時，它在更短的時間內崩潰了幾次。不確定這是否相關，但這很奇怪......
答案1
我的 MacBook 2,1 也有這個問題。您對此無能為力，但您可以重置模組，至少它會再次工作。
sudo sh -c 'rmmod ath9k; restart network-manager; modprobe ath9k'
