commit 605d7c0b05eecb985273b1647070497142c470d3 upstream. Clear bit 8 of REG_SYS_STATUS1 after MAC power on. Without this, some RTL8821CU and RTL8811CU cannot connect to any network: Feb 19 13:33:11 ideapad2 kernel: wlp3s0f3u2: send auth to 90:55:de:__:__:__ (try 1/3) Feb 19 13:33:13 ideapad2 kernel: wlp3s0f3u2: send auth to 90:55:de:__:__:__ (try 2/3) Feb 19 13:33:14 ideapad2 kernel: wlp3s0f3u2: send auth to 90:55:de:__:__:__ (try 3/3) Feb 19 13:33:15 ideapad2 kernel: wlp3s0f3u2: authentication with 90:55:de:__:__:__ timed out The RTL8822CU and RTL8822BU out-of-tree drivers do this as well, so do it for all three types of chips. Tested with RTL8811CU (Tenda U9 V2.0).

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
