WIFI6

Wi-Fi6无线网卡横评，killer 1650 vs Intel AX210 vs Intel AX200
不只有ax200，Wi-Fi6网卡大盘点

wifi6对应802.11ax，可同时支持2.4G/5G。
Intel AX210 vs Intel AX200，AX210采用M.2 2230或M.2 1216形态设计，除了支持Wi-Fi 6E，还支持蓝牙5.2，2x2天线，无线速度最高3000Mbps。高级特性方面，首先就是Wi-Fi 6E独有的6GHz频段，虽然穿墙不佳，但近距离传输速度更快。当然要想用上，外围设备也得支持才行，否则就是传统Wi-Fi 6的2.4GHz和5GHz。

速度

开启5G，VHT80，WPEQ-257 QCA988X不支持VHT160，使用手机iperf3测速，测试手机红米K30 Pro，骁龙865 SOC，接收速度57MB/s，发送速度30MB/s，

802.11a/b/g/n/ac

rfkill

内核需要开启这个支持，

[*]   RF switch input support

WPEQ-261ACN(BT)

管脚

WAKE_L(OPT) 模块输出给系统的，用于唤醒系统
CLKREQ_L 模块输出给系统的，提示是否需要给模块提供时钟，低功耗用途
W_DISABLE_L(OPT) 系统输出给模块的，可关闭模块射频信号
PERST_L 系统给模块的复位

问题

Direct firmware load for rtlwifi/rtl8188eufw.bin failed with error -2

驱动编译进内核，但是固件放到根文件系统里，所以加载驱动的时候文件系统并没有加载，导致找不到固件，想了一天，想通了，老哥我想通了。
