[pmbalsa]

Hi, 

We have an issue with our corporate Laptops with Intel AX201, wifi6 wireless card, we cannot connect more than one spacial stream, when in the specification's intel say, that hardware can do 2 spacial streams. 

Our wireless Network is Cisco, with Wifi6 Capability, and we just can get 287Mbps of Data Rate with these devices. 

As you can see, we only can get 1 SS. 

We have in the network others device, with different wireless card, and they can connect with ss2 or ss3. 

Can you help with this issue?
