验证网络在手机和另一台计算机上运行良好。
使用 Lenovo 和“Centrino Advanced-N 6205 [Taylor Peak]”。不知道该去哪里。有任何想法吗？
是的，笔记本电脑中的 WiFi 卡适用于我需要连接的所有其他网络。
路由器正在运行 LEDE。运行接入点的无线电位于信道：11 (2.462 GHz)。仅当启用加密时才会出现此问题。我认为问题出在wpa_supplicant.我使用 WPA2 连接到大量接入点都很好。该特定接入点不起作用。它不需要我非常简单的密码。使用nm-applet我可以看到纯文本的密码。这显然是正确的。

答案1
我不完全确定这解决了问题，但可能值得尝试升级您的BIOS。我已经做到了，现在看来有效。这也解决了一个奇怪的问题，我相信无线卡会阻止系统挂起。
附带说明一下，我在发表这篇文章时并不知道英特尔版本的内核运行的固件 blob。您可能想确保这是相对较新的..找出 blob 的版本可能是一项不小的任务
