Can you grab some more information about zero 2 pro from device tree? I really hope they are changing the wifi chip in that device, because there was a thread (Random wifi speed drops) where I was talking with RadxaYuntian and he said that it is “faulty” by design, and they are working on a solution with the manufacturer, but maybe using a faulty chip in an upcoming device would be a bad idea, but I can imagine that scenario.
