I want to connect the two antennas AP and STA. How can I tell if transmitting / receiving well.
Some customers call the antennas and the radios as the same device. We are going to assume that you are trying to connect an ePMP AP with an ePMP STA. You should be able to tell from the Home screen if your ePMP AP or STA is connected and at what RSSI and SNR the radio is connected at.
For in-depth details on whether it is transmitting or not, you can use the Monitor --> Wireless Status page of the radio to see what downlink / uplink RSSI and SNR the radio is operating at, as well as the MCS modes the radio is doing.
