Re: My wifi adapter doesn't work [SOLVED]
[luc@StarcClans ~]$ rtl8821cu/5.12.0.4.145.80781de, 6.2.8-arch1-1, x86_64: installed
That's not a command… 
Anyway
[luc@StarcClans ~]$ modinfo 8821cu
filename: /lib/modules/6.2.8-arch1-1/updates/dkms/8821cu.ko.zst
version: v5.12.0.4-1-g9241a6516.20210916_COEX20200730-5151
author: Realtek Semiconductor Corp.
description: Realtek Wireless Lan Driver
So the driver is perfectly there, the results in https://bbs.archlinux.org/viewtopic.php … 9#p2091989 not valid/relevant.
What are the outputs of
ip a
lsmod | grep 8821
modprobe -rv rtw88_8821cu
modprobe -v 8821cu
lsmod | grep 8821
ip aOffline

Re: My wifi adapter doesn't work [SOLVED]

also the code:
[luc@StarcClans ~]$ ip a
lsmod | grep 8821
modprobe -rv rtw88_8821cu
modprobe -v 8821cu
lsmod | grep 8821

Re: My wifi adapter doesn't work [SOLVED]
There's no "wifi package", https://aur.archlinux.org/packages/rtl8 … r-dkms-git is an AUR package, so it won't update automatically.
It'll however rebuild the kernel module when you update the kernel and that's absolutely required.
#36 also shows its module being loaded and the wifi NIC available w/ carrier and lease.
Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
