Raspberry Pi Zero 2 W to 5GHz Access Point

Question

i know that Raspberry Pi Zero 2 W are not able to connect to 5Ghz access point. Would it be possible with adapter over USB to connect to 5Ghz access point? I found several adapters in Internet, but i read always that this adapters are only compatible with 3B+ or 4B.

Answer 1

I can find no evidence that any 5 GHz WiFi dongle is supported on the Pi 0 2W. Proving a negative requires proving the absence of all possible instances - typically an impossible task - but I will stick my neck out here and submit that the answer to your question is, "No, it's not possible to connect a Pi 0 2W to a 5 GHz WiFi AP with an adapter."

I suspect the reason for this situation may be due to the lack of a driver and/or specialized firmware. I don't know (& not interested in) all of the details, but the Raspberry Pi 0 2W is the only RPi model that does not use Broadcomm's wifi hardware. The Pi 0 2W uses the Synaptics SYN43436 chip, which is said to require specialized firmware.
