Hi, I've a new MacBook Air M1 and when I close the lid working with an external monitor, the wifi speed decrease a lot!
The fastest is with the lid open (connected to monitor also)
Decrease from 51MB to 6MB.
MacBook Air 13″, macOS 12.0
The antenna is in the Display Assembly. So when the Display is open the antennas have a larger surface area and angle to send/receive signals. When the Display is closed, then the surface area and directional ability is reduced.
Hi molinajp,

Hope this helps!
Have a great day.
I'm not aware of any way to do that, but I'm not an expert when it comes to some of the more advanced features/options.
A quick search revealed these two options, but I don't know if they will work on newer versions of macOS or Apple hardware, but I have never used either method:
Changing the NVRAM settings (unfortunately requires temporarily disabling SIP and using the command line).

Using a third party app (there may be other apps, this is just an example).

Thanks. I imagine that. Is it possible to turn off the display while connected to an external monitor? Thanks.
