I have obtained and installed this driver from source at https://github.com/lwfinger/rtw89/tree/main I am having an issue where the latency during a ping test to hosts on my LAN spikes to 200ms or above. According to lwfinger, this is known and acceptable https://github.com/lwfinger/rtw89/issues/85 However, I am hoping I may be able to work with you to resolve this issue as a tester.
We know this, and it is due to power saving; i.e. tradeoff between latency and power saving. We are thinking how to improve it entirely. -- Ping-Ke
