[Solved] Problem with wireless NIC Realtek RTL8821CE 802.11ac

#1 Post by ograterol »

Hi, i have a laptop with this system configurations, but i can't configure wireless NIC driver.

I checked these links:

viewtopic.php?f=107&t=55993&p=562432&hi ... 21#p562432

https://github.com/RangeeGmbH/rtl8821ce
https://github.com/tomaspinho/rtl8821ce
https://easylinuxtipsproject.blogspot.c ... .html#ID10

and ran some tests, but was unable to resolve the issue.

In case the devs here can't get the exiting card working, replacing the wifi card on HP series 15 laptops is pretty easy. Here's a video:

https://www.youtube.com/watch?v=Pvd63UMUteQ
HP 15; ryzen 3 5300U APU; 500 Gb SSD; 8GB ram
HP 17; ryzen 3 3200; 500 GB SSD; 12 GB ram
Idea Center 3; 12 gen i5; 256 GB ssd;

In Linux, newer isn't always better. The best solution is the one that works.

Larry Finger's repo is probably your best bet: https://github.com/lwfinger/rtlwifi_new/tree/rtw88

The driver should be mainlined soon, perhaps for the 5.8 kernel release.

This is not a solution for me. I really like Linux MX, but would switch to another distribution.

Though you already checked this one:
https://github.com/tomaspinho/rtl8821ce wrote:
Your distribution may come with PCIe Active State Power Management enabled by default. That may conflict with this driver. To disable:

sudo $EDITOR /etc/default/grub

Add pci=noaer at the end of GRUB_CMDLINE_LINUX_DEFAULT. Line should look like this:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=noaer"

Then update your GRUB configuration:

Code: Select all

sudo update-grub
Reboot.
At least you can simply try by pressing E at grub screen and add pci=noaer among ro quiet splash ... then hit F10 to go on booting. If that works, make it permanent as in the quotation.

In case you'd like to try again:

Code: Select all

git clone https://github.com/tomaspinho/rtl8821ce

Code: Select all

cd rtl8821ce

Code: Select all

chmod +x dkms-install.sh ; sudo ./dkms-install.sh
(Or download via another machine, then extract https://github.com/tomaspinho/rtl8821ce ... master.zip )

Thx, Following the instructions, I installed this driver, but it still doesn't work.

Your distribution may come with PCIe Active State Power Management enabled by default. That may conflict with this driver. To disable:

sudo $EDITOR /etc/default/grub

Add pci=noaer at the end of GRUB_CMDLINE_LINUX_DEFAULT. Line should look like this:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=noaer"

Then update your GRUB configuration:

Code: Select all

sudo update-grub
Reboot.
At least you can simply try by pressing E at grub screen and add pci=noaer among ro quiet splash ... then hit F10 to go on booting. If that works, make it permanent as in the quotation.
_______________________________________________________________________

In case you'd like to try again:

Code: Select all

git clone https://github.com/tomaspinho/rtl8821ce

Code: Select all

cd rtl8821ce

Code: Select all

chmod +x dkms-install.sh ; sudo ./dkms-install.sh
(Or download via another machine, then extract https://github.com/tomaspinho/rtl8821ce ... master.zip )

Thanks, previously tried this solution but it didn't work

Are you sure the driver built and installed successfully?

Can we see

Code: Select all

lsmod | grep rtw8821ce
lspci -knn | grep -A2 Network
ip link
You do seem to have a wlan0 interface, which would suggest that the driver works (after a fashion).
mod note: Signature removed, please read the forum rules

Also this one looks ok at least:
Network: Device-1: Realtek RTL8821CE 802.11ac PCIe Wireless Network Adapter driver: rtw_8821ce

And:

Code: Select all

rfkill list

Finally, my wireless NIC is working :winner:

I folowed the instructions shown in this tutorial https://youtu.be/vPfLVsyQU_A
  1. git clone "https://github.com/tomaspinho/rtl8821ce.git" (before i had downloaded via another machine, the master.zip file instead of cloning the git repo)
  2. cd rtl8821ce
  3. sudo m-a prepare
  4. sudo ./dkms-install.sh
  5. sudo modprobe 8821ce ( i had not run this command before, but i saw with lsmod the new driver active)
  6. reboot
Huckleberry Finn and Head_on_a_Stick, thanks you very much for the support. :toast:
