我在 Xidu Tour Pro 笔记本电脑上运行 Fedora 31，大多数功能开箱即用，可以完美运行。但到目前为止我还无法使用 5Ghz 频率创建 WiFi 热点。
Fedora 连接管理器基本上说“连接激活失败”我运行了journalctl 以获取一些其他详细信息，并发现以下内容：

Feb 24 21:16:22 xidu wpa_supplicant[1091]: Note: nl80211 driver interface is not designed to be used with ap_scan=2; this can result in connection failures
Feb 24 21:16:22 xidu wpa_supplicant[1091]: wlp1s0: Failed to start AP functionality
非常感谢任何有关如何进一步调试的建议。
答案1
根据https://w1.fi/cgit/hostap/plain/wpa_supplicant/wpa_supplicant.conf：
注意：ap_scan=0/2 不应与 nl80211 驱动程序接口（当前的 Linux 接口）一起使用。 ap_scan=1 是与 nl80211 一起使用的唯一选项。
