如何确定我的wifi卡是否支持802.11ac？

我不确定我的wifi卡是否支持802.11ac。我如何找到这些信息？

如果运行iw list，请查找指定行VHT。

    VHT Capabilities (0x038071a0):
        Max MPDU length: 3895
        Supported Channel Width: neither 160 nor 80+80
        short GI (80 MHz)
        TX STBC
        SU Beamformee
    VHT RX MCS set:
        1 streams: MCS 0-9
        2 streams: MCS 0-9
        3 streams: not supported
        4 streams: not supported
        5 streams: not supported
        6 streams: not supported
        7 streams: not supported
        8 streams: not supported
    VHT RX highest supported: 0 Mbps
    VHT TX MCS set:
        1 streams: MCS 0-9
        2 streams: MCS 0-9
        3 streams: not supported
        4 streams: not supported
        5 streams: not supported
        6 streams: not supported
        7 streams: not supported
        8 streams: not supported
    VHT TX highest supported: 0 Mbps

如果您的卡不支持802.11ac，则将完全缺少此部分。

因此，在不支持802.11ac的卡上：

$ iw list | grep VHT

在一个卡，不支持802.11ac标准：

$ iw list | grep VHT
        VHT Capabilities (0x038071a0):
        VHT RX MCS set:
        VHT RX highest supported: 0 Mbps
        VHT TX MCS set:
        VHT TX highest supported: 0 Mbps
