Antenna selection is controlled by the WLAN IP internal antenna diversity algorithm, based on the link quality of each antenna.

To test the mechanism:

1. After downloading the firmware, set the 5-GHz channel.
2. In the Antenna Mode area of the main working window, select Ant 1 or Ant 2 (see Figure 4-7) from the 5GHz Diversity drop-down menu.
3. Perform a channel tune calibration by setting the same channel number or selecting the 20M or 40M Channel BW button.

For example:

1. Select channel 5200 MHz.
2. Select Ant1 in the 5-GHz Diversity area.
3. Select channel 5200 MHz.
