hcxdumptool - missing frames w/ filtering

[pipss]

I have two usb adapters, one with rtl8814au chip. This works ok with filtermode2, a could get my router AP hash w/o bothering my neighbors now. But this adapter doesn’t work in beacon mode, it shows tx power 0 dBm and PROTOCOL unassociated. I read about this issue in other forum thread. I tried to put it manually in to monitor mode, but this improves PROTOCOL only, it shos now 801.11b, but power is still 0dBm. My other adapter has mt7921u chip, it shows PROTOCOL 802.11 and power 3 dBm in beacon mode, but….. error driver is busy: failed to transmit.

Looks like both of this chips are not that good for hcxdumptool. Could you please advice some reliable two band 2.4/5 usb adapter. Thank you.
