RTL8822CE network card is not recognized.

How to drive it?

I find ERL8833CE driver source code for Linux ..

https://github.com/alanfox2000/realtek-linux/blob/master/RTL8822CE/RTL8822CE_WiFi_linux_v5.7.3_35403_COEX20190531-0e0e.20191028.7z

Drivers and application for Linux don't direct compile to FreeBSD - its ported, because Linux kernel builds by gcc, FreeBSD kernel builds clang and has their own structure, different than Linux kernel.
When drivers or application ported - they appears in the official FreeBSD ports or kernel...
Because FreeBSD drivers and application version have some time lag for same Linux application.

Is it possible to run the driver using the linux compatibility?

Short answer, no. Longer answer, this might be possible in the future with LINUXKPI (which is used by DRM and the new iwlwifi(4) driver).

Sort of, maybe.

As I understand the RTL8822CE requires the rtw88 driver. You could try net/wifibox, it provides rtw88: wifibox-rtw88 flavor.

 

[sukamu]

I don't have FreeBSD installed in this machine. But one day I'll try installing wifibox and post whether it works or not. Thanks!

 

[T-Daemon]

I'll try installing wifibox

Wait a minute, there is a native rtw88 driver, see https://wiki.freebsd.org/WiFi/Rtw88.

Which chipset was tested?

Yup, there's a Rtw88 native driver which I have tried and worked. Sadly I found FreeBSD 14 to be very unstable even for desktop use (I couldn't even install Xorg). So the option is either to use wifibox or to wait for 14 to be released. Unless they're planning to include that driver in FreeBSD 13.1 which doesn't seem to be the case according to that page:

Q: I am running 13.1-RELEASE but I cannot find the driver?

• A: That is because at the time the release was published the driver has only been in main (14-CURRENT) and not even in stable/13.
  A: The driver was merged to stable/13 and that'll be your best chance to try it out.
  A: It is unclear at this point if it'll be feasible to provide an out-of-tree version for 13.1-RELEASE -- likely not.

-CURRENT is an unsupported, development version for a reason.

to wait for 14 to be released

July 2023 at the earliest.

FreeBSD 14.0 Release Process

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms.

www.freebsd.org

The driver was merged to stable/13 and that'll be your best chance to try it out.

If it has been merged to stable/13 it will be included in 13.2-RELEASE.

FreeBSD 13.2 Release Process

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms.

www.freebsd.org

Note that -STABLE is a supported, development version.

Unless they're planning to include that driver in FreeBSD 13.1 which doesn't seem to be the case according to that page:

A: The driver was merged to stable/13 and that'll be your best chance to try it out.

It will be in 13.2-RELEASE https://www.freebsd.org/releases/13.2R/schedule/

Also, stable/13 is supported here in forums.

A: The driver was merged to stable/13 and that'll be your best chance to try it out.

The driver is definitively in stable/13: https://cgit.freebsd.org/src/tree/sys/modules/rtw88/Makefile?h=stable/13

Hi,

I have the impression the driver is still not stable.

On my pc i tried the following:

#/etc/rc.conf:
#both with: SYNCDHCP and DHCP
wlans_rtw880="wlan0"
ifconfig_wlan0="WPA SYNCDHCP"

#/boot/loader.conf:
#with and without
compat.linuxkpi.skb.mem_limit=1

#pkg
#with and without
pkg install wifi-firmware-rtw88-kmod

Nothing really works, kernel faults and reboots from the moment I do a call to internet. I use the latest version of FreeBSD, with latest patches, fresh new installation.

Anyone an idea ? Thanks in advance.

 

[SirDice]

I use the latest version of FreeBSD

Which is? Many people get confused regarding FreeBSD versions. Please specify exactly which version you tried.

The version currently running here is: 14.0-RELEASE-p6.

Thanks in advance.

 

[SirDice]

Right, that's not the latest version

RC1 for 14.1 should be available now. Could you try that? There's been quite a bit of work done on LINUXKPI after 14.0-RELEASE.

FreeBSD 14.1 Release Process

Oookay. An additional question, suppose I would do that, does working with a release candidate when 14.1 is final, give you a valid 14.1. Or can it be that some files will be different. I prefer not a beta, testing not complete version , you see what i mean? Will it give trouble at the end of the day... I wonder

 

[Cath O'Deray]

Even if there's no change between the final release candidate and RELEASE: still, you should upgrade to RELEASE in the usual way (without trouble).

 

[Relictrix]

Hi,
I switched to FreeBSD 14.1 and with following changes:

#/etc/rc.conf:
wlans_rtw880="wlan0"
ifconfig_wlan0="WPA SYNCDHCP"

#/boot/loader.conf:
compat.linuxkpi.skb.mem_limit=1

Now it works.

 

[Relictrix]

I notice now however that it's not always stable. Sometimes the connection drops.

But anyway, it's better then nothing.

Thanks for the tips :
