driver rtw88 wifi RTL8821CE

[judd]

Well, I started reading and besides adding to /boot/loader.conf → compat.linuxkpi.skb.mem_limit=1

and install by ports:

# cd /usr/ports/net/wifi-firmware-rtw88-kmod/ && make install clean

Also add to /etc/rc.conf:

kld_list="${kld_list} if_rtw88"


So far it's been almost 15 minutes with stable wifi connection.

When I install FreeBSD

Which version of FreeBSD are you using?

Also add to /etc/rc.conf:

kld_list="${kld_list} if_rtw88" from here.

Only if auto-loading is explicitly disabled

That is, only if you do devmatch_enable="NO".

Which version of FreeBSD are you using?

freebsd-version -kru
14.1-RELEASE-p3
14.1-RELEASE-p3
14.1-RELEASE-p3

That is, only if you do devmatch_enable="NO".

I haven't touched that, as T-Daemon says:

devmatch(8) is enabled by default:
/etc/defaults/rc.conf:

devmatch_enable="YES" # Demand load kernel modules based on device ids.

bileslav
Just add the above to /etc/rc.conf:
kld_list="${kld_list} if_rtw88"

Well, the point is that kld_list="${kld_list} if_rtw88" is needed only when one have devmatch_enable="NO". You don't need this with the default devmatch_enable="YES".

It's true from what I've read and as you say, but it happens to work like that!

Even if it is not technically correct.

I have just removed it from /etc/rc.conf and proved that it is not necessary to have it there, it makes no difference to downloads and system navigation.

Thanks for pointing out the error!

→ the signal works in that download range even though I am contracted for 100 MB download is not bad and stop using a wifi dongle on this Dell. I also tried installing Freebsd 14.1 on an Asus with the same wifi card but couldn't get it to work.

thanks for this.
so far so good on my end
but like you, my 100mbps is limited to 20mbps.
but at least it works

Now it works on Asus, it was my typo.
