I am getting a persistent issue with the ALFA AWUS036ACH WiFi adapter where it will sporadically disconnect. Every 5-10 minutes, it will drop its connection and syslog will output this message:
026-05-06T21:31:17.482321+01:00 thomas-P64V7 kernel: rtw88_8812au 2-1:1.0: read register 0x4c failed with -71
2026-05-06T21:31:17.486313+01:00 thomas-P64V7 kernel: rtw88_8812au 2-1:1.0: write register 0x4c failed with -71
I am on the 6.17 kernel on Linux Mint 22.3. I have also tried the driver here: https://github.com/morrownr/8812au-20210820 but this has a similar issue except the syslog lines are not reported.
Has anyone experienced this issue?
