Might have been below the radar scope of many, but finding TurboQAM clients can be a challenge...

The Pi 3 includes the BCM43438 WiFi/BT combo chip - while it's single stream, and 20MHz only, it supposedly supports TurboQAM for a 96Mbps bandwidth at the PHY...

Anyone with a Broadcom based AC1900-class BHR with Turbo support try this?

The other interesting tidbit in the Broadcom driver included with the Raspian Jessie kernel...

I'll need to dig a bit into this one, but I thought I would share... I know what it is - WiFi Direct, but I'm not seeing the upper layer stuff in the kernel - that's why it's interesting...

Code:

                Device Capability Bitmap: 0x25
                .... ...1 = Service Discovery: 0x1
                .... ..0. = P2P Client Discoverability: 0x0
                .... .1.. = Concurrent Operation: 0x1
                .... 0... = P2P Infrastructure Managed: 0x0
                ...0 .... = P2P Device Limit: 0x0
                ..1. .... = P2P Invitation Procedure: 0x1

                .0.. .... = Group Formation: 0x0
            Listen Channel: Operating Class 81  Channel Number 1
                Attribute Type: Listen Channel (6)
                Attribute Length: 5
                Country String: US\004
                Operating Class: 81
                Channel Number: 1
 
BTW - if you want to find your PI's on the LAN... use ARP...

Code:
arp -a | grep b8:27:eb | grep -Eo '[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}'
