I originally used firmware 5.0.0. Then I have tried 9.9.6 I have lying around here from my distro. That version behaves like the old 5.0.0 version. Finally I switched to 9.9.11 from current linux-firmware repository. That doesn't work at all for me unfortunately: [ 221.076279] rtw_8822cu 2-1:1.2: Firmware version 9.9.11, H2C version 15 [ 221.078405] rtw_8822cu 2-1:1.2: Firmware version 9.9.4, H2C version 15 [ 239.783261] wlan0: authenticate with 76:83:c2:ce:83:0b [ 242.398435] wlan0: send auth to 76:83:c2:ce:83:0b (try 1/3) [ 242.402992] wlan0: authenticated [ 242.420735] wlan0: associate with 76:83:c2:ce:83:0b (try 1/3) [ 242.437094] wlan0: RX AssocResp from 76:83:c2:ce:83:0b (capab=0x1411 status=0 aid=4) [ 242.485521] wlan0: associated [ 242.564847] wlan0: Connection to AP 76:83:c2:ce:83:0b lost [ 244.577617] wlan0: authenticate with 76:83:c2:cd:83:0b [ 244.578257] wlan0: bad VHT capabilities, disabling VHT [ 246.866182] wlan0: send auth to 76:83:c2:cd:83:0b (try 1/3) [ 246.871830] wlan0: authenticated [ 246.892754] wlan0: associate with 76:83:c2:cd:83:0b (try 1/3) [ 246.911045] wlan0: RX AssocResp from 76:83:c2:cd:83:0b (capab=0x1431 status=0 aid=3) [ 246.940608] wlan0: associated [ 247.152308] wlan0: Connection to AP 76:83:c2:cd:83:0b lost [ 248.912821] wlan0: Connection to AP 00:00:00:00:00:00 lost [ 249.105517] wlan0: authenticate with 76:83:c2:ce:83:0b [ 251.482183] wlan0: send auth to 76:83:c2:ce:83:0b (try 1/3) [ 251.486765] wlan0: authenticated [ 251.508731] wlan0: associate with 76:83:c2:ce:83:0b (try 1/3) [ 251.521904] wlan0: RX AssocResp from 76:83:c2:ce:83:0b (capab=0x1411 status=0 aid=4) [ 251.565233] wlan0: associated [ 251.720602] wlan0: Connection to AP 76:83:c2:ce:83:0b lost [ 253.527904] wlan0: Connection to AP 00:00:00:00:00:00 lost [ 253.728243] wlan0: authenticate with 76:83:c2:cd:83:0b [ 253.728921] wlan0: bad VHT capabilities, disabling VHT [ 256.014184] wlan0: send auth to 76:83:c2:cd:83:0b (try 1/3) [ 256.019608] wlan0: authenticated [ 256.044702] wlan0: associate with 76:83:c2:cd:83:0b (try 1/3) [ 256.062049] wlan0: RX AssocResp from 76:83:c2:cd:83:0b (capab=0x1431 status=0 aid=3) [ 256.093117] wlan0: associated [ 256.169071] wlan0: Connection to AP 76:83:c2:cd:83:0b lost [ 258.145286] wlan0: authenticate with 76:83:c2:ce:83:0b [ 260.626182] wlan0: send auth to 76:83:c2:ce:83:0b (try 1/3) [ 260.630495] wlan0: authenticated [ 260.652783] wlan0: associate with 76:83:c2:ce:83:0b (try 1/3) [ 260.666201] wlan0: RX AssocResp from 76:83:c2:ce:83:0b (capab=0x1411 status=0 aid=4) [ 260.708596] wlan0: associated [ 260.769613] wlan0: Connection to AP 76:83:c2:ce:83:0b lost [ 262.770668] wlan0: authenticate with 76:83:c2:cd:83:0b [ 262.771272] wlan0: bad VHT capabilities, disabling VHT [ 265.158184] wlan0: send auth to 76:83:c2:cd:83:0b (try 1/3) This goes on forever. I finally tried 9.9.10 and 9.9.9, they also behave like 9.9.11.
