  • Red Hat Enterprise Linux 9.4
  • HP Z6 G5 A Workstation
  • MediaTek RZ616 WiFi 6

  1. Ensure wireless access point is broadcasting on at least a 5GHz channel, reaching link speeds of 2400 Mb/sec. Connect the MediaTek RZ616 device to the wireless access point on this network.

Please note that this is the only recommendation for general use of MediaTek RZ616 to reach optimal speeds. The following recommendations are required specifically to pass the RHEL9 Wifi6 Hardware Certification test.

  1. To complete the RHEL Wifi6 Hardware Certification Test, also connect the test server to the wireless access point via ethernet port with connection speed greater than 1GbE. For certification, a 2.5GbE NIC was installed on the test server and connected to a Wifi7 Router with 2.5GbE capable port via direct ethernet connection.

This addition is necessary to pass the RHEL Wifi6 Certification test due to the test process used in the TCP Throughput section of the test. There seems to be a bottleneck in the iperf3 test procedure with the recommended test environment setup (test server to wireless access point via ethernet and wireless access point to test system via wireless connection to MediaTek RZ616 test device). The iperf3 test is receiving reported speeds from the entire test server to test device connection, including the ethernet port. Therefore, if the ethernet port connection capabilities are not greater than the wireless device capabilities, the test will fail due to a bottleneck in the reported speeds of the entire connection, unrelated to the test device itself. Please note that the test server must be connected to the wireless access point via ethernet connection because the MediaTek RZ616 test device connection is shut down as part of the Wifi6 certification test. Connection between the test device and the test server would be terminated, resulting in an incomplete test, if all test environment connections were to be done through the wireless access point.

  1. Allow the wireless access point DHCP server to assign an IP address to the wireless connection (test system) and the direct ethernet connection (test server). If the IP addresses are on different subnets, then manually assign the IP addresses to match the subnet of the DHCP server. It can be beneficial to also change the default wireless access point subnet to decrease other traffic which may be using the default subnet address. The wireless access point subnet was changed from the default for certification testing.

  2. Conduct the Wifi6 Hardware Certification test as any other device with assigned test server IP address and wireless connection to MediaTek RZ616 IP address.
