At least it would be helpfull which sticks or chipsets are supported. The performance is based on the given infrastructure and the build of the sticks. You can buy many sticks with 2 antennas, but I don't know if they work.
Hello, I'm struggling with Wifi for my Raspberry Pi 4 on LE. I'd like to upgrade with an USB stick that can perform Wifi 5(AC). Could anyone give me a suggestion of a stick that would work?
