I will certainly be curious. Quite annoyed my nanoHD with a 1300Mbit down PHY and 1560Mbit up, rate still only does 700Mbit throughput in either direction on my laptops, despite my Galaxy S10 also doing the same with an 866Mbit PHY.
CPU load on the nanoHD is really low, makes me wonder if its a bug in the Intel AX200 cards in the laptops or Ubiquiti put some weird speed cap in the firmware.
Although I've long since given up trying to understand the weirdness that can happen with WiFi to Ethernet bridges. On some WiFi APs in the past I used to struggle to max out my broadband speed, even though I could do several times faster than that to LAN clients. I can't even begin to understand what weird network tomfoolery was going on there.
