驗證網路與手機和另一台電腦正常工作。

使用聯想“Centrino Advanced-N 6205

$$ Taylor Peak $$”。不知道該去哪裡。有什麼想法嗎？ 是的，筆記型電腦中的 wifi 卡適用於我需要連接的所有其他網路。

路由器正在執行 LEDE。執行接入點的無線電位於通道：11 (2.462 GHz)。僅在打開加密時才會出現問題。我認為問題出在wpa_supplicant. 我用 WPA2 連接到大量的接入點就好了。這個特定的接入點不工作。它不需要我非常簡單的密碼。使用nm-applet我可以以純文字形式查看密碼。顯然是對的。

路由器 (LED)

從帶有 LEDE 的 AP 端，我看到了這個，

wpa_supplicant 2.4 股票（Ubuntu 16.10）

從wpa_cli，我得到，這個

<3>CTRL-EVENT-SCAN-STARTED 
<3>CTRL-EVENT-SCAN-RESULTS 
<3>WPS-AP-AVAILABLE-AUTH

那是一堆，然後以

wpa_supplicant 2.6

建構一個新版本的 wpa_supplicant 只是為了測試。不用找了。

其中大部分只是出於我自己的目的，也可能與之相關

• https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=146418我也連接到 N 路由器。

我不完全確定這是否解決了它，但可能值得嘗試升級您的 BIOS。從那以後我已經這樣做了，它現在似乎可以工作了。這也解決了一個奇怪的問題，我認為 wifi 卡會阻止系統暫停。

附帶說明一下，在我發表這篇文章時，我不知道英特爾版本的韌體 blob 核心執行。您可能想確保這是相對較新的..找出 blob 的版本可能是一項非次要任務
