Step 1. Install iPerf on Mac.

Please visit the official website of iPerf to download the software: https://iperf.fr/iperf-download.php#macos

Note: If you need to test speed between EAP and wireless clients, please ensure that you download iPerf2.

Step 2. Set up a static IP address for Mac.

If you test the wireless speed between EAP and Mac, please go directly to the next step.

For other tests, you need to assign static IP addresses for the network devices and test computers. To assign a static IP address for Mac, go to System Preferences--->Network--->choose the current adapter--->Advanced… --->TCP/IP, choose Manually for “Configure IPv4”, and assign the addresses as needed, and you can refer to the above FAQ.
