有人知道如何让 hostapd 以超过 400 Mbps 的吞吐量工作吗？我使用的配置文件如下所示，但我无法使用它们运行 hostapd：
interface=wlp5s0
driver=nl80211
ssid=testingwifi
hw_mode=a
channel=149
ht_capab=[HT40+]
ieee80211n=1
ieee80211ac=1
vht_oper_chwidth=1
vht_oper_centr_freq_seg0_idx=42
我只能使用 149、153、157 频道。我使用的是支持 800 Mbps 以上的 H270N-wifi 服务器，但出现以下错误：
