Wi-Fi Performance Issues on Radxa Zero 3W Compared to Raspberry Pi Zero 2W – ZERO 3W/3E

admin

Wifi performance depends on many factors, and an interesting read: forum.armbian.com/topic/5246-wifi-performance-benchmark-test/

For example, my (wifi) 3W outperforms my 5C-lite, different kernel, same AP.

cpu governor: ondemand, 2.4 GHz
