我是 Ubuntu 新手。我買了一台 Dell 3537 - 預先安裝了 ubunbtu。升級到最新更新後，我的 wifi 停止運作。我發現https://www.kernel.org/pub/linux/ker...able/v3.9-rc4/並安裝了驅動程式。但是，我觀察到以下幾點：
互聯網在幾分鐘內工作完全正常，然後斷開了幾秒鐘。這種情況不斷發生。我很確定與 wifi 的連線也已斷開，但這並沒有反映在我的網路管理員中。我的另一台運行 Windows 7 的筆記型電腦在連接到同一網路時沒有任何問題
我嘗試收集一些信息，這可能有助於解決我的問題。任何幫助表示讚賞。
它有幫助，我運行了由 Wild Man 和 Krytarik 開發的腳本，在 anewguy、chili555、llua 的幫助下並提到這裡 輸出位於 -http://pastebin.ubuntu.com/7101870/
