Hi, thanks for reporting this. Can you please attach here the output of $ inxi -Nn CC:
(none) =>
ouaurelien inxi doesn't seem to be on the machine, even in /usr/sbin. (It's not on the other machine I installed from the same USB.) What does it do, and for what should I be looking. I've just found inxi in the software lists, so I nkw know what it does. Is there anything required to run it? Network: Device-1: Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet driver: r8169
IF: eno1 state: up speed: 100 Mbps duplex: full mac: 6c:02:e0:0b:a8:8c
Device-2: Realtek RTL8821CE 802.11ac PCIe Wireless Network Adapter driver: N/A
Just a note to say that from Mageia 8, inxi will be installed automatically. It is very good for collecting different system information in a compact form. If you are curious, do $ man inxi ! please provide output of "lspcidrake -v" lspcidrake -v generates a lot of output, but I think the 2 relevant lines are: r8169 : Realtek Semiconductor Co., Ltd.|RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller [NETWORK_ETHERNET] (vendor:10ec device:8168 subv:103c subd:85b3) (rev: 15) rtw88_8821ce : Realtek Semiconductor Co., Ltd.|RTL8821CE 802.11ac PCIe Wireless Network Adapter [NETWORK_OTHER] (vendor:10ec device:c821 subv:103c subd:831a) Checking card types, I learned that 802.11ac is a later designation, not a/c (which would be an older, much more limited, combination). I can confirm the error. The same date: It occurred after the updates on 15.1.2021. The same wifi-device: RTL8821CE Even if I go back to the previous kernel-version, the problem remains. CC:

mail.gerstenberg Guys, please have a look at https://github.com/tomaspinho/rtl8821ce#wi-fi-not-working-for-kernel--59 as this only seems to be since kernel >= 5.9 is in place. CC:

doktor5000 Note that the link given above (thank you Florian) shows a workaround: "Wi-Fi not working for kernel >= 5.9 The Linux Kernel 5.9 version comes with a broken rtw88 module developed by Realtek that has poor compatibility with most revision of the 8821ce chip. You must disable it by adding the following to your module blacklists (/etc/modprobe.d/blacklist.conf): blacklist rtw88_8821ce Then, make sure you have the rtl8821ce module correctly installed. Turn off your computer, wait a few seconds (to force firmware reload) and then turn it on again." Assigning to the kernel/drivers group. Assignee:

kernel hi, seems I forgot to fix and re-enable the 3rdparty rtl8821ce for kernel 5.10 series :/ sorry about that... I've fixed it for Cauldron in the currently building 5.10.9-1 that will land in mga7 testing after 5.10.8-2 that currently passing through QA is validated and pusheg. Thomas Backlund:
> will land in mga7 testing after 5.10.8-2 that currently passing through QA
I'm willing to test that, if you'd like.
kernel-5.10.9-1.mga7 is now building and should show up in Mageia 7 Core Updates Testing after some hours... does kernel-5.10.9-1.mga7 work any better ? (In reply to Thomas Backlund from comment #15) > does kernel-5.10.9-1.mga7 work any better ? How do I get that to download and install? rpm commands or control-centre? Mirror lists to have checked? P.S. when installec, should a reboot bring it back immediately, or are there extra steps? either go to media manager, enable "Core Updates Testing" and select the kernel from there. or in console as root: urpmi.update "" urpmi --media Testing kernel-desktop-latest and if you are using any dkms package, urpmi --media Testing kernel-desktop-devel-latest after its installed, reboot with the new kernel and see if it works again It took a couple of reboots to get its full attention, but wlp3s0 is now there and functioning. Thanks. Confirm "8821ce.ko.xz" is back again in "/usr/lib/modules/5.10.9-desktop-1.mga7/kernel/3rdparty/rtl8821ce" and working => with kernel 5.10.9-1 in Updates-testing. Thanks CC:
