said by owlyn:Testing here in a clean RF environment within a faraday cage lab environment using 2:2:2 configuration with various enterprise Cisco APs. Associated rate is 300Mbps with RSSI of -29dB and lower. The WiFi connection is as ideal as you can get for 5Ghz and is more than capable of testing against a 50/10 cable Internet connection. The downstream comes out at 50mbps+/- and 2Mbps+/- upstream when running ShaperProbe on Windows host machines configured with an Intel WiFi chipset radio. Mind you it does not do this to internal or external iperf servers.
WiFi results are not reliable indicators of your actual speed. There are troo many variables. I recently had to change my WiFi channel due to interference. A neighbor apparently got a new router and was using the same channel as I was. After changing the channel, speed and reliability went back to normal.
