Arch Linux User Repository

hi all, I follow the step yby @tomaspinho but not work.

when i run the command dmesg | grep failed

[ 4.674336] platform regulatory.0: Direct firmware load for regulatory.db failed with error -2 [ 4.674338] cfg80211: failed to load regulatory.db [ 4.757727] 8821ce: module verification failed: signature and/or required key missing - tainting kernel

i think this is the problem, but i can't find the solution.

i use arch linux 5.4.3-arch1-1 #1 SMP PREEMPT Fri, 13 Dec 2019 09:39:02 +0000 x86_64 GNU/Linux

Thanks

Same issue here as ASLok described. I was not able to make it work :(

@tomaspinho No differences, got the same error.

This driver works with linux-lts but need to remove second tar.gz in the driver/ directory, currently have to use it - https://github.com/alanfox2000/realtek-linux/blob/master/RTL8821CE/RTL8821CE_WiFi_linux_v5.5.2.1_35598_COEX20180712-3232.20191029.part1.rar

@ASLok Just built this package without issues on Manjaro with Kernel 5.3.12-1-MANJARO.

Please make sure you have:

1) fully removed this package (and any previous versions) from your system (pacman -R)

2) fully removed all dkms installations of this module:

2.1) run "dkms status"

2.2) run "dkms remove module/version --all" for all outputs of previous command

3) install this package again

==> dkms install rtl8821ce/1.0.5.r74.g27f98a5 -k 5.3.11-arch1-1 Error! Bad return status for module build on kernel: 5.3.11-arch1-1 (x86_64)

Tried linux-lts 4.19.84-1-lts got the same error

Never mind -- just saw that this issue was fixed already in revision 59 (https://github.com/tomaspinho/rtl8821ce/issues/55). My package was older than that so reinstalled the package with today's version of HEAD and everything works fine. So all fine for me, thanks!

@senorsnor you are going to wait for someone who knows how to fix it... while you can install LTS linux and wait for help, if you can, because my laptop only can boot up with 5.0 + kernels JJAAJ

@jackoneill @senorsnor watch it, other exaMPLE about suffering :) all for the bad code made by realtek and the kernel developpers without wanting in the tree( something normal)

After upgrading my kernel to 5.3 today (and later 5.3.1), my wifi didn't work anymore. Downgrading to 5.2.14 solved the issue for me.

Log entries related to this module, including multiple stack traces, at https://pastebin.com/kLQzQrPA

Does anyone have any idea how to fix this? I would like to stay up to date with all packages including kernel if possible. If I can provide more info just let me know.

@jackoneill a few weeks ago when I started using the laptop that had this wireless card this package only works with pre 5.2 kernels. Some example of suffering because my laptop won't boot up with nothing older than 5.2 kernels. Other few problems there and here for the features not compatible and @tomaspinho having to fix it for us (thanks ). In addition are the problems that this module will have with future kernels abis rather than having it builtin in the kernel tree .. I thought at the start that this laptop won't work ever with the WiFi card for example xD
