Hi,
I want to install Arch Linux on my new (just bought) laptop with RTL8821CE 802.11ac PCIe Wireless Network Adapter,
but RTL8821CE 802.11ac PCIe Wireless Network Adapter is not detected (rfe 4 isn't supported) by the current Arch Linux install ISO (ARCH_202111):
"ip link" shows only the loop-back interfeace:
$ ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
$ lspci -k | grep -A3 Network
01:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8821CE 802.11ac PCIe Wireless Network Adapter
DeviceName: WLAN
Subsystem: AzureWave Device 3040
Kernel modules: rtw88_8821ce, wl
$ dmesg | grep rtw

[ 9.011496] rtw_8821ce 0000:01:00.0: failed to setup chip information
What can I do to install Arch Linux on this laptop? - there is no wired LAN socket in this laptop :-(

Hello,
I have the same chip as you in my current laptop. The chip is not recognised by linux and there is no package in the official arch repositories to help.
I use the package rtl8821ce-dkms-git from the AUR in order to use it.
I see two possibilities for you to install Arch on your laptop:
- either you have an ethernet / USB adapter, which will be recognised by Arch
- or you can build a custom archiso image (see https://wiki.archlinux.org/title/Archiso for more details).
I hope this will help,

Hi dsac,

I use the package rtl8821ce-dkms-git from the AUR in order to use it.
Does your chip work correctly with the rtl8821ce-dkms-git package?
Can you connect to WiFi on your Arch Linux machine using it?
Thanks!

My chip works fine with it.
I never had any issue with this module.
Nonetheless, it requires to use linux-lts now, as the sources use a header that has been removed from the linux-header package.
I am sorry, I should have said so in my first post.

It looks like kernel 5.16 will have support for rtl8821ce rfe4 in the rtw88 driver:
https://git.kernel.org/pub/scm/linux/ke … 8856053572
as of now it has not been backported to v5.15, so you can wait or try the release candidate build from the AUR (linux-mainline, the maintainer also has a private binary repository)
To install arch without building your own iso you could maybe use usb tethering with your phone if you do not have a usb network adapter.

Great news! Thanks! :-)

Clever idea! it will work for sure, but after having installed the system I will still have no WiFi access probably, so I will wait for kernel 5.16 :-)
Thanks a lot!

I can confirm that rtl8821ce works with 5.16.0-rc3-1-mainline kernel. I had trouble with it for a month, when it suddenly stopped working.

Rules for problems.
