Hi! I'm a beginner in Linux OS, I used Mint for months, and I'm using now Ubuntu and installed Debian with Ubuntu on my laptop. At the time of installing Debian I found this error message of missed drivers - maybe - "rtw88/rtw8821c_fw.bin", after installing I noticed that my Debian has no wifi like my Ubuntu has. How can I solve this and my laptop infos. according to Ubuntu are:

Ive tested both drivers (tomaspinho and lwfinger) for a while, and In my case Ive found this version worked better for me :

https://github.com/lwfinger/rtw88

Code: Select all

git clone https://github.com/lwfinger/rtw88.git
cd rtw88
make

I went to the mentioned paragraph in that article and it has these commands:

sudo apt install bc module-assistant build-essential dkms

cd rtl8821ce
sudo m-a prepare
sudo ./dkms-install.sh

I downloaded the packages on Ubuntu and tried to install 'em manually on Debian but I have this error message:

I didn't install Debian by CD rom but with USB flash, and my CD/DVD writer has problems in writing discs. How can we solve this situation? for example if we can use the USB flash.

This thread should be pinned as an example of what NOT to do :
- For a missing firmware, suggest to build third-party drivers instead of install missing firmware...
- Try to install Ubuntu packages on Debian...

firmware-realtek

* Realtek 8821C firmware (rtw88/rtw8821c_fw.bin)

That is not wifi driver.. It just bringhts bluetooth and think ethernet one too; its needed rtw8821ce (its not in debian repository)

Requirements

You will need to install "make", "gcc", "kernel headers", "kernel build essentials", and "git".

Code: Select all

sudo apt-get update
sudo apt-get install make gcc linux-headers-$(uname -r) build-essential git

For all distros:

git clone https://github.com/lwfinger/rtw88.git
cd rtw88
make
sudo make install

please tell us what we have to install... we install third-party drivers cos there is missing wifi firmware for our wifi device (8821CE) in debian's repositories.

It might help other people if you identify the device by vendor id, and show the kernel msg asking for the specific firmware that is missing.

something like this should work

Code: Select all

lspci -nn | grep Net
dmesg | grep firmware

Sometimes firmware can lag getting into the repo, so there might be some newer in testing or sid repo. In that case you can just download the deb and install locally with apt or dpkg.

Good luck

This is getting confusing. OP asked about missing firmware which will be solved by installing firmware-realtek from the non-free repository.
https://packages.debian.org/bullseye/firmware-realtek

But according to our friend bester, one also needs to compile and install the driver for this device. @pascal111 follow bester's instructions to install the driver. Then reboot and your wifi device should be active.

I downloaded the packages on Ubuntu and tried to install 'em manually on Debian but I have this error message:

Downloading and attempting to install Ubuntu packages is absolutely the wrong way to manage packages on Debian. You can use apt on command line, or Synaptic, or that Gnome software thingy to install packages from the official Debian repositories.
Adding outside packages or mismatched repositories can create a Frankendebian. Read this carefully - DontBreakDebian

And here's a concise video on using Synaptic - https://www.youtube.com/watch?v=OP7h0nG1fGg

I mentioned that I'm a beginner, and the Terminal was asking me putting CD disc that I haven't because I used USB flash - in fact - to install Debian, also it seems Debian is the original distro of its derivatives and it's some difficult with beginners, so such problem like we have here can be serious one for beginners and it causes that he can't work with the OS on his computer and he will be like paralyzed person, really I felt I can't function with my computer. So, the basic problem that prevented Debian responding to our solution was in "Software & Update", accidentally, I succeeded to add link for apt in "Software & Update" instead of CD rom choice to make Debian communicate with internet resources and get the wanted data like next image after I added the link:

I got the link from here: https://www.debian.org/doc/manuals/apt- ... co.en.html

Then I ran the mentioned commands of one of suggested sites in this topic and they worked this time without asking CD rom:

sudo apt install bc module-assistant build-essential dkms
git clone https://github.com/tomaspinho/rtl8821ce
cd rtl8821ce
sudo m-a prepare
sudo ./dkms-install.sh

I restarted my computer, and searched for Wifi and found it, and it works now and I'm communicating with you from my Debian through Wifi. Thanks everyone for your efforts.

I tried tomaspinho's driver, but it doesn't work because it requires insecure booting from BIOS. I have tried lwfinger, but it is no longer available. Please see the snapshot attached.

Thanks. You are correct: "w" was missed out. Good news is working perfectly, no need to set insecure boot in BIOS.

if you are getting issues with power management RTL8821CE driver wifi after suspend THEN:
https://miloserdov.org/?p=5930

PCIe Activate State Power Management
Your distribution may ship with PCIe Activate State Power Management enabled by default. It may conflict with this driver. To disable:
sudo $EDITOR /etc/default/grub

Add pci=noaer to the end of GRUB_CMDLINE_LINUX_DEFAULT. The line should look something like this:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=noaer"
