I have managed to finish testing the ASUS RT-BE88U, where I explored the heat management, I performed a teardown of the WiFi 7 router, I ran single-client tests and most importantly, some multi-client tests using net-hydra developed by Mr Jim Salter.
Additionally, since the router supports MLO, I have ran some tests to check the throughput and I also used FLENT to check the average latency.
