Maintainership
As of 28th February 2019, I will no longer have access to a machine with the Wi-Fi chip supported by this module. Therefore, I will no longer be able to maintain this repository from a functionality perspective.
If you are able to continue development, please contact me.
I don't have the know how to maintain it, it was good while it lasted. Obrigado :)
The laptop I had with this Wi-Fi chip was a work laptop that I've since returned, because I'm in between jobs. However, I will try to keep merging Pull Requests and helping people out until someone more suited to the task comes along.
RTW88 driver is getting merged into Linux 5.2
https://www.phoronix.com/scan.php?page=news_item&px=Realtek-RTW88-WiFi-Linux-Driver
EDIT: Oops, it's currently only supports 8822, but that's little bit closer to mainline support for this chipset.
Great news! Once that supports rtl8821ce and is merged into the mainline, I will discontinue this project.

Wow thanks for the git repo, the RTL8821CE driver package is really nice, the install.sh included compiles everything and now the 5ghz band is recognized and power management works (no more issues with resume from sleep). Maybe @tomaspinho could point to this new resource (or maybe the original manufacturer's FTP URL?). BTW, I'm running a Lenovo 530 ARR on KDE neon (18.04) if it guides anyone.
Thanks for bringing those to my attention. I'd like to update this repo with the latest code and keep the DKMS stuff/Arch AUR package going. Can someone link me to the original Realtek FTP so I can verify their origin?
The people of endlessm also updated the sources in their repo. https://github.com/endlessm/linux/tree/master/drivers/net/wireless/rtl8821ce This source looks safe and you already used it in the past.
Not sure if it's the correct one I found, but the realtek driver ftp seems to be not public. You need username+password for it. As far as I read, only some oems have access. So we are forced to trust alanfox2000 or endlessm.
Hey, can someone help me out testing updated sources (from endlessm)? https://github.com/tomaspinho/rtl8821ce/pull/54
Hey, can someone help me out testing updated sources (from endlessm)? #54
Which branch should I checkout ?
If you are able to continue development, please contact me.
Hi,
did you find someone to 'continue development' or not? I have some Java experience and C development 25 years before. Does it helps?
@HBartolin no, I did not. I've just been maintaining this as best as possible without having access to the actual hardware. @harryyoud and @hashlib have been a major help, though.
@tomaspinho Well, I have hardware that use RTL8821CE. I have basic knowledge of programming. If you want, I can be from tester to admin. If something doesn't know, Internet is here. :-)
I wouldn't mind giving some time to help test either. I've written a fair amount of C code, however I don't have much experience writing drivers. I wrote a keyboard driver but that's about it. If there's some tasks I could contribute to please let me know.
Just found on LKML the expected release date of the driver for 8821CE with rtw88 : 2020.
Yeah, not looking good. The upstream maintainers don't like the quality of code Realtek has been putting out, so they may even veto it outright. Only time will tell.
To tomaspinho: Not sure if this helps but it seems the Lenovo S145-IWL that I recently picked up at a Best Buy for about $230 has this particular Realtek card in the M.2 slot. Perhaps get a low cost computer and continue to maintain the driver that way? So far, except for the Realtek card, it's a great little Linux computer. Even has NVMe slot in addition to SATA.
Hey @tomaspinho! Huge thanks for putting this repo together!! The driver works like a charm on Fedora 31!
Hey @tomaspinho ,
Since @shakna-israel mentioned in #139 the possibility that the kernel handles the wifi, I was curios to test that.
I removed the driver and tested the latest Ubuntu mainline kernel on my Ubuntu 18.04 (5.6.4 atm). Sadly I hadn't any wifi.
After rebooting to the signed hwe kernel used before to remove the 5.6.4 again, I've wifi currently. Can't see any sign of the module in place, but could you confirm that it's not installed?
- Kernel is 5.3.0.46.102 according to apt
dkms statusoutput has no sign of rtl8821ce module:vhba, 20200106, 5.3.0-45-generic, x86_64: installed vhba, 20200106, 5.3.0-46-generic, x86_64: installed
Is there anything I have to check, or is it handled by Ubuntu's default kernel?
Greetings, Lukas
rtw88 only supports 2 adapters, at the moment, this
vendor: 10ec ("Realtek Semiconductor Co., Ltd."), device: b822 ("RTL8822BE 802.11a / b / g / n / ac WiFi adapter") vendor: 10ec ("Realtek Semiconductor Co., Ltd."), device: c822 ("RTL8822CE 802.11ac PCIe Wireless Network Adapter")
https://cateee.net/lkddb/web-lkddb/RTW88.html
Look at the output of lsusb, if the output is 10ec:b822 or 10ec:c822, then it’s lucky that your adapter is supported by the kernel.

lsmod shows that the 8821ce module is loaded, even though you deleted it via dkms, so wi-fi works. I do not know how dkms works when removing / adding kernel modules. I build them through make && make install.
Hm, how can I make sure the module is being removed again?
In the past I remember if I run the dkms-remove.sh I didn'thave wifi after reboot 🤔🤷♂️
Yeah I can manually unload it, but how do I completely remove it, that it's not there to be loaded on boot?
