我正在尝试共享我的无线网络（wlan0），并按照本教程操作：https://linuxalfi.wordpress.com/2011/11/08/connectify-for-linux-with-single-wireless-interface/
问题是：如果启动了 hostapd，我将无法使用 wpa_supplicant 连接到我的网络。另一方面，如果我连接到网络，我无法启动 hostapd。这两个 hostapd 和 wpa_supplicant 不能一起启动。
当我尝试启动 hostapd 时出现以下错误：
root@me:~# hostapd /etc/hostapd.conf Configuration file: /etc/hostapd.conf Using interface new1 with hwaddr 84:4b:f5:4c:89:ab and ssid "Linux-Hotspot" Failed to set beacon parameters new1: Unable to setup interface.
如果启动了 hostapd，则使用 wpa_supplicant 时会产生以下错误：
Successfully initialized wpa_supplicant new0: CTRL-EVENT-SCAN-STARTED new0: SME: Trying to authenticate with ac:86:74:26:54:72 (SSID='Ktx My Dinh' freq=2432 MHz) new0: SME: Authentication request to the driver failed new0: CTRL-EVENT-SCAN-STARTED
这是iw list
root@me:~$ sudo iw list Wiphy phy0 max # scan SSIDs: 4 max scan IEs length: 2257 bytes Retry short limit: 7 Retry long limit: 4 Coverage class: 0 (up to 0m) Device supports RSN-IBSS.

我该怎么做才能解决这些问题？提前致谢。
答案1
检查 iw 列表输出的底部是否有类似这样的内容：
valid interface combinations:
* #{ managed } <= 1, #{ P2P-device } <= 1, #{ P2P-client, P2P-GO } <= 1,
total <= 3, #channels <= 2
* #{ managed } <= 1, #{ AP } <= 1, #{ P2P-client } <= 1, #{ P2P-device } <= 1,
total <= 4, #channels <= 1
（这是我的 Raspberry Pi 3 对 wlan0 显示的。）请注意，该设备仅支持两个（托管和 AP）接口之间的单个通道。
尝试更改您的 hostapd.conf，以便指定的频道与您尝试加入的网络的频道相匹配。
