You can test speed with one of my ath builds if you want to give it a try.
@badulesia - the PHY rate it is reporting will say 866mbps but with a 2x2 client at 80mhz - PHY speed is a theoretical speed and is not achievable in the real world when real world wifi overhead is included. When you test with speedtest, iperf, or similar synthetic bench something in the 500-600 mbps for a 2x2 wifi 5 client is a great result.
