I applied both these patches, tested an 8821CU, and the news are good: The number of kernel warnings and adapter hangs has gone down considerably. The signal levels on 2.4GHz bands have improved noticeably. There is the occasional station coming in 30dB lower than on nearby adapters. I wasn't able to find a pattern here. I can now run these adapters in IBSS and 802.11s modes on the 2.4 GHz band. That was not possible before. I am impressed with the improvements in these patches.

Tested on RTL8811CU, these two patches fix both issues. 2.4 GHz networks now work perfectly fine. Tested-by: ValdikSS <iam@valdikss.org.ru>
