我的笔记本电脑上有QCA6174 802.11ac无线网络适配器，运行的是 Ubuntu 16.10 和 Linux 内核版本 4.13。无线适配器使用ath10k驱动程序。我正在尝试将笔记本电脑设置为使用 802.11ac 的接入点。为此，我使用wpa_supplicant以下配置文件：
network={
frequency=5180
ssid="Test"
mode=2
key_mgmt=NONE
disable_ht=1
disable_vht=0
}
之前的配置运行完美，当我扫描频谱时，我在 AP 列表中找到了上述 SSID。但是，如果我将频率更改为其他频道，例如 [60] 即 5300 MHz 而不是 [36] 即 5180 MHz，wpa_supplicant 可以正确执行，但我看不到 SSID。那么我是否缺少任何配置？
我尝试使用hostapd，其配置如下：
interface=wlan1
driver=nl80211
ctrl_interface=/var/run/hostapd
ssid=travelmate
hw_mode=a
channel=36
ht_capab=[HT40+]
ieee80211n=1
ieee80211ac=1
vht_oper_chwidth=1
vht_oper_centr_freq_seg0_idx=42
但我在所有频道上都收到以下错误：
Configuration file: /etc/hostapd/hostapd.conf
wlan1: IEEE 802.11 Configured channel (36) not found from the channel list of current mode (2) IEEE 802.11a
wlan1: IEEE 802.11 Hardware does not support configured channel
Could not select hw_mode and channel. (-3)
wlan1: interface state UNINITIALIZED->DISABLED
wlan1: AP-DISABLED
wlan1: Unable to setup interface.
wlan1: interface state DISABLED->DISABLED
wlan1: AP-DISABLED
hostapd_free_hapd_data: Interface wlan1 wasn't started
nl80211: deinit ifname=wlan1 disabled_11b_rates=0
这与监管领域有关。那么我该如何解决上述问题呢？
