When trying to run the throughput test with three wireless clients(one client on 2.4G, one on 5G, one on 6G) connected to my TP-Link Archer BE 800 Wi-Fi 7 router, we encountered that the clients that are connected to the router and the upstream LAN port are getting disconnected and are losing their IP.

The clients are connected with 40 MHz, 160 MHz and 320 MHz channel widths on 2.4G, 5G and 6G respectively. This issue is observed when we run the peak load possible on the clients (580 Mbps on the 2.4G client, 2.9 Gbps on the 5G client and 5.8 Gbps on the 6G client).

We observed that the clients are getting de-authenticated and losing their IP addresses. In that instance, when we observed the wireless packet captures, we saw that there were no beacons from the router on any of the wireless bands.

Has anyone else observed this issue? What could be the reason behind this behaviour? Any insight or support would be really helpful.

P.S. The wireless clients we are using are created on Intel BE200 radios. I've attached the relevant router configuration and the supplicant logs recorded.
