With an iAP-215 and 802.11ac NIC having the fastest possible a-VHT-80sgi-3ss (1300Mbits/sec) connection, the maximum performance I'm seeing is 341Mbits/sec with iperf 2 and 464Mbits/sec ftp transferring a 2.3GB compressed file.
Should I stop bludgening my head expecting to see something near 1300Mbits/sec performance because real world speed of 802.11ac is actually not that fast?
iperf -c server -t 10 -P10 -w 64k = 341Mbits/sec
I know the source and target are more than fast enough: Using a 1GB wired Ethernet NIC connection, the same tests fills the pipe at 960Mbits/sec, and on a 10GB LAN connection, it blows through at 3500Mbits/sec.
The iAP-215 with 802.11ac is rated at 1300Mbits/sec (which is 300Mbits faster than 1Gbit Ethernet) (doesn't that beg the question, shouldn't the AP have a 10Gbit Ethernet port?)
The client uses an ASUS AC1900 USB-AC68 USB 3.0 WiFi adapter that supports 1300Mbits/sec at 3 Spacial Streams (which is the only way to get a 1300Mbits connection).
Client adapter is five feet from iAP-215, no obstructions between. AP and client are at desk height and oriented toward each other. iAP-215 is powered with 802.11at POE.
Can anyone else check their results, please?
BTW, the trick to get a wireless adapter to work with Windows Server 2012 R2 is to install the latest manufacturer's driver and then add the WS2012 R2 WLAN Feature (Server Manager, Manage, Add Roles and Features) which will then reveal a "Connect/Disconnect" menu option when right-clicking on the Wireless Adapter in Network Connections. Subsequently (perhaps after a Windows restart), the traditional Wireless icon will appear in the System Tray.

*** Note: a-VHT-80sgi-3ss indicates the fastest connection possible for the iAP-215.
*** Note that ftp throughput with a 2 Spacial Stream (a-VHT-80sgi-2ss) connection is about 50MBytes/sec. Windows Network Connection Adapter Status displayed speed rate for a a-VHT-80sgi-2ss connection is typically 866Mbits.
