I have an Intel BE200 Wi-Fi card in my laptop in the room next to the room where the router is.
I just found that opening the laptop lid, I get a real improvement in the speed (tested with iperf3). This makes sense since the antennas for a laptop usually are in the lid behind the display.
Strangely, the speed for my smartphone, which is 6E, not 7, I get a real poor upload speed when using the 6GHz band (also tested with iperf3).
