Same WIFI card, Radxa Zero 3w Video RX is worse than Phones

[Li-Tianming]

I tried the same wireless network card, RTL8812AU

Radxa can only receive videos at a short distance, but with same RTL8812AU card android phone can receive videos much farther than Radxa, but Radxa can receive MAVLink OSD information without video.

I tried to change rtw_tx_pwr_idx_override=30 parameter, but it seems not work.

I hope I don't need to use a spectrum analyzer to test the transmission power, like this

Please upgrade to the newest v1.9.2, we've reverted drivers for the RTL8812AU.
