I have an issue on my new Lenovo Legion 5 Pro 16ach6 with its wifi card : Realtek RTL8852AE - PCIe 2.0 with ubuntu 20.04 and the 5.12.9 kernel (it's work on Windows 10).

I followed this topic : Network driver for Realtek 8852 20.10 but Modeprobe doesn't find the module "rtw_8723de" (which doesn't exist, I think It's a mistake in regards to rtw88 repository) and the 2 .ko created doesn't work : rtw89core.ko or rtw89pci.ko (we can see it in the lspci).

I tried different kernels like 5.8, 5.11, 5.12 but I have the same problem. Ubuntu 20.04, 21.04, the last Manjaro with gnome... I think its ok in the bios : I disabled secure boot and an AMD protection for CPU and no results ! There is an option with "discrete" and "dynamic" graphics but except a choice between the AMD graphic chipset and the NVIDIA video card, I have no difference.

When I try this solution : https://github.com/lwfinger/rtw89, I have this :

Update I have an UEFI Dual boot with EFIs partitions (I start on Ubuntu EFI with grub). Hibernate mode is disabled on Windows and I shutdown with restart mode for it. Bios information :

AMD Platform Security Processor : Enabled (If I disable that, I have nomore bluetooth and no wifi)

Device Guard : Disable

Secure boot : Disable

Secure boot status :  Disable

Platform Mode : User

Reset to setup mode

Restore Factory Keys

Update I tried this solution too :

echo "blacklist ideapad_laptop" | sudo tee /etc/modprobe.d/ideapad.conf

Update When Ubuntu is starting, I have these messages (quickly) :

ACPI BIOS Error (bug): Could not resolve symbol [_SB.PCI0.PB2],

AE_NOT_FOUND (20210105/dswload2-162)

ACPI Error: AE_NOT_FOUND, During name lookup/catalog (20210105/ps

Update 2 I tried all of these methods but no wifi :

Update 3 Now, when I want disable the module, I can't anymore if I use the wget solution :

sudo modprobe rtw89pci 

Erreur de segmentation (core dumped) # segmentation fault

sudo modprobe -r rtw89pci 

modprobe: FATAL: Module rtw89pci is in use.

Update 3 Same thing for the copy solution of the .bin (make) to the/lib/firmware/rtw89 :

sudo modprobe rtw89pci 

Erreur de segmentation (core dumped) # segmentation fault

sudo modprobe -r rtw89pci

Update 3 Disable the fast boot on Windows didn't work. I used a powercfg.exe /hibernate off to disable this mod ever (option disapear). But I tried to enable that to uncheck the option fast boot but it didn't change things.

Update 4 Ok I removed an error at the beggining of the session when I checked "Reset to setup mode" in the bios. But no wifi. After that, I reinstalled Ubuntu to be safe and I stay on the kernel 5.8.0.43 (there is 2 kernels with the 20.04 : 5.8.0.55 by default doesn't work, no boot).

integrity: Problem loading X.509 certificate -65

Update 5 Many peoples have the same problem (on arch mainly : no surprise because it didn't work on Manjaro). The conversation continue here (I continue to tell you if there are interessant news) : https://github.com/lwfinger/rtw89/issues/2

Update 6 The new version of rtw89 works very well for Ubuntu 20.04 and 21.04. Problem solved.
