Lower the transmit power from 28dBm to 17dBm on both devices to increase
the throughput. There was no need to set the transmit power to high,
because the distance is only 150ft. The high transmit power may have
caused receiver overload, and thus the low throughput.

 

To enable the Transmit Power setting, click Operation Mode and uncheck the
box beside "Green". Select the Country/Region then click
Save/Apply
