Arch Linux User Repository

If your wifi adapter doesn't work and you see a line like this when running sudo dmesg | grep -i firmware,

[24672.978460] rtw_8814au 5-2:1.2: Direct firmware load for rtw88/rtw8814a_fw.bin failed with error -2

that means your system lacks the firmware needed, try upgrading linux-firmware to 20250408.c1a774f3-1 or later.

If your distro doesn't provide these newer versions of linux-firmware, run these commands to install the firmware manually.

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

cd rtw88

sudo make install_fw

Reminders:

1. If your USB wifi adapter is in CD-ROM mode, you need to use the command usb_modeswitch or eject to switch it to "Wi-Fi Mode" first.

2. Before installing this package, make sure your system has the corresponding kernel headers and the package base-devel installed.

3. You have to manually blacklist or remove any conflicting drivers installed except the in-kernel rtw88 driver.

4. Experimental support for RTL8814AE chip (device id: 10ec:8813) was added, please test and report here if you have this card, thanks.

For me, this package completely broke my system. Not even pacman worked. I had to boot from a boot stick and remove it.

There is a .git directory in /usr/src/rtw88-*/.git/.

Please remove.

TP-LINK Archer T2E (b821) well supported! Thanks!

@1llum1n4t3d, I thought I was the only one experiencing this.

In any case, @lwfinger makes it clear in the README that he is not the one who can solve such problems, repeatedly. Therefore, it is better to contact linux-wireless@vger.kernel.org.

On my own, I can add that I added more modules to the blacklist, maybe this will help:

#
# Blacklist conflicting rtw88_* modules
#

blacklist rtw88_8723de
blacklist rtw88_8723d
blacklist rtw88_8821ce
blacklist rtw88_8821c
blacklist rtw88_8822be
blacklist rtw88_8822b
blacklist rtw88_8822ce
blacklist rtw88_8822c
blacklist rtw88_core
blacklist rtw88_pci

Hello I have realtek 8821ce chipset and very bad wifi connection and connection keeps dropping..Please help me for any fix and solutions?

In /etc/default/grub I have put pci=noaer at GRUB_CMDLINE_LINUX_DEFAULT=

lsmod | grep rtw

rtw_8821ce 16384 0 rtw_8821c 94208 1 rtw_8821ce rtw_pci 36864 1 rtw_8821ce rtw_core 266240 2 rtw_8821c,rtw_pci mac80211 1236992 2 rtw_core,rtw_pci cfg80211 1073152 2 rtw_core,mac80211

In /etc/modprobe.d/blacklist.conf I have put:

blacklist rtw88_8821ce blacklist rtw88_8821c blacklist rtw88_pci blacklist rtw88_core

In /var/lib/NetworkManager/NetworkManager-intern.conf have put [connectivity].set.enabled=false and set BSSID manually in gnome wifi settings app.

In /etc/modprobe.d/rtw.conf I have

options rtw_pci disable_msi=1 options rtw_pci disable_aspm=1

Wifi is constantly disconnecting. Does anyone have solutions for fix?

@jonathon, I figured out them for myself empirically, but I cannot guarantee that they will work for everyone.

Hopefully my changes won't break anything. What do you think of it?

@PRESFIL, what would you think about including a file to blacklist in-kernel drivers when this driver package is installed?

==> dkms install --no-depmod -m rtw88 -v r87.6ccdad5 -k 5.14.10-arch1-1 Error! Bad return status for module build on kernel: 5.14.10-arch1-1 (x86_64) Consult /var/lib/dkms/rtw88/r87.6ccdad5/build/make.log for more information.

I tried to cat /var/lib/dkms/rtw88/r87.6ccdad5/build/make.log but it does not exist. Trying to install through yay.

Edit: Seems like running yay -S rtw88-dkms-git again fixed it, somehow.

@o_flipper, do you have linux-headers installed? You must manually install the correct linux-headers for all your kernels.

ArchWiki states that I should not include linux-headers in the dependency list (because they are individual for each user). Read about build process and DKMS.
