No fix at this time, been wrapped up in other projects and asked to leave this one as-is for now

The alternative WAP was a spare new out of box Ubiquiti UAP-AC-HD
The NIC in question was a Wi-Fi 6 AX200
Settings for both above devices were at default at ~650 Mbps

I’m not a WiFi expert - enterprise routers and switches are more my wheelhouse - and I understand there are hardware limitations, but I haven’t found a single online source that has been able to achieve near-optimal WiFi speeds with this device
Selling a device on its protocol speeds seems dishonest, and if there are caveats of having achieved these speeds in a lab, it’d be much appreciated if someone could link those
