Hello,
Our test team reports that they get reliable firmware crashes on ax200 radios against multiple
APs when running 100Mbps UL + DL traffic (100Mbps in both directions).
This happens on 5.19-ish kernels as well as 6.2.9+.
ax210 radios in same setup are much more stable.
Please let us know if you would like additional debug information, including binary
crash dump files from the radio....
