hAP ac lite - Max Data Rate of 180Mbps on 5GHz

Hi,

I just bought a hAP ac lite device and configured it as dual AP. What is strange to me is that the Max Data Rate reported from inSSIDer app is 180Mbps for the 5GHz frequency.

Any idea why is that?
I’ve tried chaging differnet channels but it’s the same story.
The AP is with the latest rc - 6.39rc55.
Firmware: 3.36

hAP ac lite has only a single chain for 5GHz band, and you (according to your screenshot) have a 40MHz-wide channel, which gives you a 180Mbps theoretical maximum (or 200 Mbps with a short guard interval). Try increasing channel width to 80 MHz go get more (theoretical) bandwidth.
