最近，我喜欢将我的路由器从 802.11n 升级到 802.11ac。我买了一个 Atheros QCA6174 mini PCI-E 无线网卡来替换我的旧卡。不幸的是，它可以完美地与 802.11n 2.4G 配合使用，但无法启动 802.11ac 5G 网络。
当我启动 hostapd 时，它在尝试启动时停止start_dfs_cac()。
我阅读了此https://wireless.wiki.kernel.org/en/users/drivers/ath10k/configuration并尝试通过ieee80211d=1and启用 DFS，ieee80211h=1但它也不起作用。
从内核驱动程序中删除 REGD 是我唯一的选择吗？
这是我的日志。
