Comment 3 for bug 1987252

The output above was with Intel Wi-Fi 6 AX201. And another colleague in EU had Intel 8200 series and the output was all *with* NO_IR.

So it must be dependent on the vendor/model/generation of WiFi cards. In any case, I'm more than happy to offer any information required and test something as necessary. Thanks,
