 ====== RTL8852BE WiFi adapter on Debian 12 Bookworm ======
+===== DKMS self compiled module does not work! =====
+:!: **WARNING**! The recipe explained in this page actually does not work! At the end you will have a kernel module and a firmware blob that enable the WiFi adapter, they even support the WiFi scanning function, showing the available ESSIDs, but if you try to associate with an access point, the action fails with the following messages in loop:
+<code>
+wlan0: authenticate with b2:32:6e:53:27:2a
+wlan0: 80 MHz not supported, disabling VHT
+</code>
+What actually does work is installing **kernel 6.12** from Bookworm backports, along with the **firmware-realtek** package:
+  * **[[https://packages.debian.org/bookworm-backports/linux-image-6.12.22+bpo-amd64|linux-image-6.12.22+bpo-amd64_6.12.22-1~bpo12+1_amd64.deb]]**
+  * **[[https://packages.debian.org/bookworm-backports/firmware-realtek|firmware-realtek_20241210-1~bpo12+1_all.deb]]**
+===== Compiling the module with DKMS =====
+:!: **WARNING**! The kernel module obtained with this procedure actually does not work!
 The Realtek WiFi Network Controller **RTL8852BE** is not supported by the **6.1.0 Linux kernel** shipped with **Debian 12 Bookworm**. In this page you can find the steps required to compile and install the required kernel module and firmware.
