we have a Cisco 2106 WLC with software version 220.127.116.11 and 2 LAP1252.
Everything is enabled for 802.11n, an Intel 4965 client is connecting correctly, shows that 300 mbit per second. But the real throughput (with the iperf-tool) is just 60mbit/s.
The client is working in 802.11a frequency-band and 40 mhz channel bandwidth. all 11n rates are enabled.
now the questions: what's wrong with it? did we forget something?
thanks for your answers.

How are you testing the throughput? You will have different results if you test between a wired client and a wireless client (best in this case) or between two wireless clients.. Also you will have better results if you use UDP or if you open several connections..
