pi zero 2w+rtl8812au+wfb-ng 25.01, 60% packet lost

[cxy0303]

I used Raspberry Pi Zero 2w and RTL8812au as the sky end, and Raspberry Pi 3 and RTL8812au as the ground end. During testing, when ping the sky end on the ground end, the packet loss rate was over 50%, and the network card on the sky end was hot. Previously, using Raspberry Pi 2 as the Sky end, everything was normal. Has anyone also encountered this situation?

Is that why I use the default power of -1dm for my network card? But the same situation is normal on Raspberry Pi 2
