我在使用 Intel 7265 WiFi 晶片組 [2] 的 Debian 8 [1] 上遇到嚴重的 WiFi 穩定性問題。我隨機斷開了互聯網連接，儘管 WiFi 連接似乎完好無損。我可以透過關閉/開啟 Wifi 或重新啟動系統來重新獲得連線。上個月情況變得更糟 - 更頻繁地失去連接，<5 分鐘 - 所以我決定重新安裝作業系統。沒有成功 ：-（
我研究並嘗試過，但沒有結果。我發現晶片組失去了對最新韌體版本的支持。我發現了一些命令來讀出/一些錯誤[3]。一個可能的解決方案——這對我來說是難以適應的——似乎非常相似問題連結在這裡。以及所需的輸出[4]。
既然我正在使用non-free驅動程序，我想，也許我應該嘗試一下這些free驅動程序。也許事情會變得更好。然而，我擔心我沒有經驗來刪除現在活動的有故障的驅動程序，安裝打開的驅動程序，並重新配置內核。但是，在一些幫助下，我肯定會嘗試一下。謝謝 ：）

答案1
作為解決方法我已經為路由器 5G 網路設定了一個獨特的名稱，並在機器上為其建立了一個 wifi 設定檔。斷線停止了！
看來問題的根源在於 linux 驅動程式對多個 wifi-stardad 的 SSID 管理。
