[solved] No kernel driver for Network controller, only on linux-lts

Hello all,

I have installed arch freshly on my laptop, the problem for me seems to be that i cant connect to wifi networks. i had this problem before on windows where i needed to download drivers from the lenovo site to get wifi working. Now after a long time of searching the web i cant figure out how to get my network controller to work.

when looking at lspci -k i find the text below. this does not say that is has any kernel drivers in use why i am thinkin that that is the cause (i can be very wrong)

03:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8852AE 802.11ax PCIe Wireless Network Adapter
        DeviceName: Realtek RTL8111E Ethernet LOM
        Subsystem: Lenovo Device 4852
        Kernel modules: wl

I already downloaded end build the driver pakage i need from https://github.com/lwfinger/rtw89. when reading the readme i see:

sudo modprobe -rv rtw_8852ae
sudo modprobe -v rtw_8852ae

these give me the error

 modprobe: FATAL: Module rtw_8852ae not found in directory /lib/modules/5.15.44-1-lts

You'll need the linux-headers and linux-lts-headers

upstream install instructions often need adaptations for software to work well on arch.

You have uninstalled the manually build binary version and are now using the one created by makepkg (& installed through pacman) from the aur PKGBUILD linked by seth ?

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

I spend a few hours trying to get it working, but got tired. I uninstalled the linux-lts kernel and i hope that the normal linux kernel will keep working.
Thanks for the help Lone_Wolf and Seth, really appreciated it.
