開發板為NXP下的LS1012ARDB，使用LSDK1809工程，在內核中配置cfg80211和mac80211驅動，加上高通QCA9880網卡的ath10k驅動，編譯后運行，sta模式運行正常，連接到5G路由器速度到867M，但是5G的AP模式帶寬只有20Mhz，速度很低，需求是帶寬達到80MHz，速度為867M。hostapd的組態檔參考https://wireless.wiki.kernel.org/en/users/Drivers/ath10k/configuration中的Example hostapd config to use 11ac VHT80 mode with ath10k。
以下為摘錄hostapd啟動無線的操作，有能解答的，重謝！！

Fallback to 20 MHz
注意日志這部分，channel設定問題導致頻寬回落到了20MHZ。
可以試試下面的配置。注意HT80和11ac以及channel的設定。
option channel auto
option hwmode 11ac
option htmode HT80
option txpower 20
option mode ap
option wmm 1
