How do I find if my Wi-Fi card supports MIMO (Multiple Input Multiple Output)?

Question

I want to know if my Wi-Fi card supports MIMO (Multiple Input Multiple Output), and specifically how to find the number of antennas.

Is there a command I can run to find out?

Answer 1

If you're using windows type in command line: netsh wlan show all | find /I “MIMO”.

If you see MU-MIMO : Supported then it means yes.

I'm not sure how to do this in Linux aside from checking network card model and looking at technical specification. That will give you 100% correct answer.

But You can try though this: iw phy | grep index; you will see something like this:

HT TX/RX MCS rate indexes supported: 0-15

If you see the index above 7 that means your card supports MIMO. Why is that ?

MIMO requires at least two antennas to work (means two spatial streams of data) and this table explains index / streams relation.
