Unfortently, the machine with iwx can't move beyond ~300 mbps. I've tried
both iwx and 1G Ethernet as USB dognle, so, I can't prove that.

But Unifi thinks that this machine is connected as 42 dBm Ch. 64 (5 GHz, 160
MHz) and it says: Rx Rate 780 Mbps; Tx Rate 1.17 Gbps.

And in beacon I see: Channel Width: 80 MHz, 160 MHz or 80+80 MHz BSS
Bandwidth (1).
