Unsurprisingly, we see that WiFi 6E and six clients perform the best, with two of them staying around 50ms throughout the test. The rest climbed to around 100ms and above, which is a bit far from ideal performance. Moving on, it was time to run a 4K traffic simulation on five client devices, and while latency has definitely increased, it’s not as dramatic as I expected.

In fact, the performance is very similar to what I saw when luxembourg telegram data testing the ASUS TUF-AX4200. It’s still not perfect latency, so you’ll want to limit the number of clients or rely on a cable if you absolutely need 5 devices to stream 4K at the same time.
After that, I turned on heavy browsing traffic for simultaneous 1080p streaming, and the first graph shows whether the first type of latency was affected.

Apparently, that was the case: the WiFi 6E client was going crazy, exceeding 100ms 10% of the time. The rest stayed around 100ms, with one client, ZimaBoard, exceeding 100ms for the entire test.
