Hello,
I am wondering why my 5Ghz wireless speed is so much slower than it should be? When I setup the wAP AC device the absolute maximum I can push in a momentary spike is 399Mbps, but average is around ~200-240Mbps regardless of the device I use.
The router is setup as an AP only and all routing is handled by a Debian box which is 10Gbit capable and, using a Cisco AP, can push up to 800Mbps without issue. There is a simple default bridge with all interfaces attached.
Here is a 30-second iPerf from my MacBook to the Debian gateway (you can see how it drops off)

Additional notes:
1.) There is very little interference where I live and there are only 1 client connected.
2.) Test results are taken from 4 meters away, line of sight.
3.) I have changed channels, regulatory domains and have reset the device several times and still see the same results. Never over ~300 consistently.
