AX210 unicast packet send issues ( retry packet )

[bhryu]

https://community.intel.com/t5/Wireless/Problem-injecting-unicast-packets-using-pcap-library/m-p/1270909#M35057

I'm having the same problem as this link.
When firmware iwlwifi-ty-a0-gf-a0-59.ucode is used, 15 retry occurs, and when firmware iwlwifi-ty-a0-gf-a0-72.ucode is used, about 80 retry occurs.

I'm currently using linux(linux-5.19.17) and would like to know how to fix whether I need to modify the driver or change the firmware.

If yes, when did the issue start?

Did you make any recent hardware/software changes that might cause this issue?

The wireless card, did you purchase it separately or did it come installed on the computer?

The number of retransmissions changes depending on the firmware.

send too many retransmissions (about 15~80) when sending single unicast packet in monitor mode.

 iwlwifi-ty-a0-gf-a0-59.ucode -> about 15 retransmissions 

iwlwifi-ty-a0-gf-a0-72.ucode -> about 80 retransmissions 

I want to know how not to do retransmission.....

bhryu, Thank you very much for providing that information.

For this scenario, it is important to mention that when you separately install a wireless card on a computer that is what we called "Wireless Integration". The thing about that process is that there are a lot of components that come into play, like for example: board, Wireless card, drivers, PCI adapters, antennas, m.2 ports, all those parts need to be fully compatible for the proper functionality of the Wireless connection. 

There is also regulatory information about the "Wireless Integration" that you can verify in the following links:
