我正在尝试设置无线 AP 以通过 Wi-Fi 共享有线互联网连接。
这是一台新组装的 PC，起初我以为无线网卡可能有缺陷，但在 Windows 下尝试 connectify 时一切正常。
我为此选择了一张无线网卡，希望它不会给我带来问题（ath9k 驱动程序），但我不知道我做错了什么。
该卡是 TP-Link TL-WN781ND，带有 AR9285 Atheros 芯片组。
即使是最简单的 hostapd 配置，也可以使用此 .conf 文件
interface=wlan0
driver=nl80211
ssid=test
channel=1
hw_mode=g
country_code=IT
（即使没有 country_code 也是同样的行为）并且启动它sudo hostapd /location/to/hostapd.conf似乎成功运行，但它不会生成任何网络。
我在 3 个不同的设备（Android 平板电脑、iOS 手机、Ubuntu 笔记本电脑）上扫描 Wi-Fi 网络，但网络没有出现在任何设备上。
它给我的唯一警告/错误是：
$ sudo hostapd hostapd.conf
Configuration file: hostapd.conf

对我来说，除了这一点之外，一切似乎都正确执行Failed to update rate sets in kernel module，即使我不得不说，我看到有人在出现此消息时仍能使用 hostapd。
有人能帮助我或为我指明正确的方向吗？
非常感谢

我设法让它工作了。
就在放弃并购买另一张卡之前，我尝试了另一个 PCIe 插槽...将其从 1x 插槽移至 4x 插槽...现在它运行完美！
仍在接收，Failed to update rate sets in kernel module但现在它可以按预期工作。
