为当前内核更新了 rtl88x2bu 驱动程序。
Updated driver for rtl88x2bu wifi adaptors based on Realtek's source distributed with myriad adapters.
Realtek's 5.6.1.6 source was found bundled with the Cudy WU1200 AC1200 High Gain USB Wi-Fi Adapter and can be downloaded from Cudy's website.
A few versions ago (around 6.4 IIRC), rtw88x2bu support has been added to the mainline Linux kernel. This repo will be maintained until we either receive a few comments on https://github.com/cilynx/rtl88x2bu/issues/270 that the mainline driver is working well or MaxG87 and cilynx agree that no feedback means no one is still using this driver and we make the executive decision to archive it.
NOTE: As of Linux v6.16, the maintainer is no longer using the driver themself. Due to ongoing stability issues with either the Wifi dongle or the driver of this repository the maintainer switched to a new Wifi dongle that is supported by the mainline kernel. Therefore, the maintainer will not be able to detect subtle issues themself anymore.
Build confirmed on:
5.4.0-91-generic on Linux Mint 20.2 (30 November 2021)5.15.89 on Manjaro (3 February 2023)5.19 on Ubuntu 22.46.1.0-9-amd64 on Debian Bookworm6.1.* to 6.12.* (self-compiled) on Debian and Ubuntu 22.046.10.3 to 6.12.10 on Debian Trixie6.13.0 (self-compiled) on Debian Trixie6.17.0 - 7.2 on Cachy OS (make CC=clang LD=ld.lld -j16)As of lately the maintainer experienced issues with the driver on Debian Testing, covering several Linux Kernel versions. More details can be found in issue 280. Any suggestions on how to troubleshoot or fix this are welcome there too.
NOTE: The fixes for Linux v7.2 broke compatibility with Linux v6.14 and older. The scope of the fixes was so big that it was decided not to use the conditional code inclusion technique for this case. If you need to use the driver on Linux v6.14 or older, please use the an older version of the driver (e.g. fc158d1f71b9e5dfcd1fccaf4d28725b65086e3b).
In order to make direct use of the driver it should suffice to build the driver
with make and to load it with insmod 88x2bu.ko. This will allow you
to use the driver directly without changing your system persistently.
It might happen that your system freezes instantaneously. Ensure to not loose important work by saving and such beforehand.
If you want to have the driver available at startup, it will be convenient to
register it in DKMS. This can be done using the script deploy.sh, for either
Please consult --help for more information and consider reading the script
before executing it.
Since registering a kernel module in DKMS is a major intervention, only execute it if you understand what the script does.
Some users reported problems due to Unknown symbol in module. A likely cause
of this is that the cfg80211 module is not present in the Kernel. You can fix
this by running it:
sudo modprobe cfg80211
Another reported cause was that old deployments of the driver were still present in the system directories. One reported solution was to forcibly remove all old driver modules. This is a drastic measure. It may prevent you from using other external WiFi adapters. See this issue for more information.
If you want to proceed anyways, you can run the following commands:
sudo dkms remove rtl88x2bu/5.8.7.4 --all
find /lib/modules -name cfg80211.ko -ls
sudo rm -f /lib/modules/*/updates/net/wireless/cfg80211.ko
Starting from Linux 5.18, some distributions have added experimental RTW88 USB support (include RTW88x2BU support). It is not yet stable but if it works well on your system, then you no longer need this driver. But if it doesn't work or is unstable, you need to manually blacklist it because it has a higher loading priority than this external drivers.
Check the currently loaded module using lsmod. If you see rtw88_core,
rtw88_usb, or any name beginning with rtw88_ then you are using the RTW88
driver. If you see 88x2bu then you are using this RTW88x2BU driver.
To blacklist RTW88 8822bu USB driver, run the following command. It will
replace the existing *.conf file with the echoed content.
echo "blacklist rtw88_8822bu" | sudo tee /etc/modprobe.d/rtw8822bu.conf
Then reboot your system.
Secure Boot will prevent the module from loading as it isn't signed. In order
to check whether you have secure boot enabled, you couly run mokutil --sb-state. If you see something like SecureBoot disabled, you do not take
to setup module signing.
If Secure Boot is enabled on your machine, you either could disable it in BIOS or UEFI or you could set up signing the module. How to do so is described here.
