我不确定我的 wifi 卡是否支持 802.11ac。我怎样才能找到这些信息?
答案1
如果运行iw list
,请查找指定的行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,则此部分将完全缺失。
因此,在不支持 802.11ac 的卡上:
$ iw list | grep VHT
在一张卡片上做支持802.11ac:
$ 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
