如何在 hostapd 中配置接入点 5Ghz 的通道?

如何在 hostapd 中配置接入点 5Ghz 的通道?

我尝试使用 hostapd 创建 WIFI 接入点。我有以下无线适配器:

Network controller: Qualcomm Atheros AR9462 Wireless Network Adapter (rev 01)

它支持 WIFI 802.11a/b/g/n 您将在下面找到命令 iw list 的结果

我已经写了以下 hostapd.conf

#the interface used by the AP
interface=wlan_local

# "a" simply means 5GHz
hw_mode=a

# the channel to use, 0 means the AP will search for the channel with the least interferences (ACS)
channel=40
ieee80211d=1
country_code=FR
ieee80211n=1

# 802.11ac support
ieee80211ac=1
wmm_enabled=1

ssid=MYSSID
auth_algs=1
wpa=2
wpa_key_mgmt=WPA-PSK
rsn_pairwise=CCMP
wpa_passphrase=MYPASSWORD

我尝试了从 0 到 40 的不同通道,但启动服务 hostapd 时仍然出现以下消息

hostapd[1937]: wlan_local: IEEE 802.11 Configured channel (40) not found from the channel list of current mode (2) IEEE 802.11a
hostapd[1937]: wlan_local: IEEE 802.11 Hardware does not support configured channel

您有什么想法吗?谢谢
