After 2025-05-04 system update I had an issue with my Wi-Fi module rtw8814a

Support System Updates
1

I have the Wi-Fi adapter TP-Link Archer T9UH v1 [Realtek RTL8814AU], and to have it functional, I have to use the package rtw88-dkms-git.
I installed this package, for the firts time, on 5 February 2025, and during the months, during a system update, I never had an issue.

But after applying the 2025-05-04 Update I encountered an issue about this module.

I received an error message about the fact that the file /usr/lib/firmware/rtw88/rtw8814a_fw.bin already exists on the file system.

So I had to uninstall the package rtw88-dkms-git, and after the reboot the device wasn’t recognized as expected.

So, connecting via USB Tethering of my phone, I had to reinstall the package rtw88-dkms-git.

I repeat: since 5 February 2025 I never encountered this issue.
Maybe, to avoid this error for the next system update, should I add
NoExtract = /usr/lib/firmware/rtw88/rtw8814a_fw.bin in the config file /etc/pacman.conf ?

Just for the record:
the file /usr/lib/firmware/rtw88/rtw8814a_fw.bin is owned by linux-firmware 20250408.c1a774f3-1 package.

rtw8814a_fw.bin was installed through the AUR Package, but is now removed: Use rtw8814a_fw.bin provided by linux-firmware - aur.git - AUR Package Repositories

Now it is part of linux-firmware. Maybe because rtw88_8812a and rtw88_8812au is now part of the kernel? Maybe rtw88_8814au will come soon, when ready…

Read the pinned comments: AUR (en) - rtw88-dkms-git

Just overwrite it one time and it is done.

Thank you for the suggestion, but the comment which you mentioned, suggests to update the firmware, not to overwrite the file (sorry: surely I haven’t been able to properly understand).

However, I reinstalled rtw88-dkms-git (is the git version, so is up-to-date), so, there is the chance that now is properly updated? How can I check?

EDIT:

the comment also say:

try upgrading linux-firmware to 20250408.c1a774f3-1

And the stable update has installed exactly this version.

I have a somewhat similar issue. After the upgrade and a restart the WiFi device seems to be lost.

Was also my case, but I reinstalled rtw88-dkms-git and has starts to work again.

So you have a different problem: open a dedicated topic.

Oh well… and what package do we have here?

Look, the file /usr/lib/firmware/rtw88/rtw8814a_fw.bin was already there, installed by rtw88-dkms-git. Now linux-firmware tries to install /usr/lib/firmware/rtw88/rtw8814a_fw.bin` and says: “Oh wait! It is already there! I stop here.”

Now you have 2 options:

  1. Overwrite:
pamac update --overwrite "/usr/lib/firmware/rtw88/rtw8814a_fw.bin"
reboot
  1. Remove, Update, reboot, reinstall, reboot:
pamac remove rtw88-dkms-git
pamac update
reboot
pamac build rtw88-dkms-git
reboot

I guess you did the later one…

The version 20250408.c1a774f3-1 as suggested here:
https://aur.archlinux.org/packages/rtw88-dkms-git#comment-1019463

And indeed the lastest stable updated has updated linux-firmware to this version.

Yeah, I executed the second method:

Remove, Update, reboot, reinstall, reboot:

Also if the last reboot hasn’t been necessary: I unplugged/plugged in the Wi-Fi adapter and has been immediately recognized.
