You should use Wireshark (on both sides) to check whether the frames
look as expected. From the ASCII debug output it is hard to tell what
kind of frame that is.

Also the 'O's indicate that the PC cannot keep up with the sample stream
and drops packets.

I assume the other side of the connection is a PC with a normal WiFi
card. Make sure to adapt the ARP entries to match the MAC of the card.
The WiFi card also needs static ARP entries for the SDR.

This means your PC is not fast enough to process the incoming samples.
Either it is too slow, or frame detection is triggered too often due to
a DC offset, for example.
