[Realtek RTL8192EU] wifi adapter unstable / no connection

Blorg001 · December 30, 2024, 11:35pm

Hi everyone! I hope someone could help me out with this as I’m not sure what to do after trying to find a solution. I may not be a pro enough linux user to use garuda although i’ve been using different distros for quite a long time, so keep the possible answers clear, pls.

This is just a couple of weeks old installation of garuda. I started with another tp-link adapter when choosing the distro for this machine and from the beginning, the main issue with all the distros I tried was intermittent wifi cycling: it dropped and then woke again after a random length of sleep or something. Garuda worked the best so I gave it a shot but: over time the wifi performance has turned into abdysmal quality. However, the same usb wifi adapter (relatively big model with one antenna) works reliably (albeit a bit slowly) in another machine next to this with bodhi 7 hwe (kernel 6.2).

I’d like to have one of the latest kernels on this machine because it has an intel A310 gpu and to my undrestanding, there has been improvements as late as 6.10 or 11 if I remember right.

To troubleshoot more I switched to another tp-link (TL-WN823N) wifi adapter and it has exactly the same problem.

Disabling ASPM didn’t improve the performance.

Are the latest gpu improvements gonna be added into the mainline kernel and if yes, when?
I think I should install the 6.6 lts kernel and try it, but with such a horrid connection, I’m not able to. So how can I get the right files to an usb stick and install from there?

Here’s some information about the system and a couple of other troubleshooting tries:

Welcome to the forum @Blorg001.

Try installing the proprietary Realtek driver package from the AUR:

8192eu-dkms

Be sure there is a blacklist file in /etc/modprobe.d on the following kernel module:

rtl8xxxu

You will also likely want to “disable MAC address randomization” and “disable Wifi power saving” to help improve your connection’s stability/reliability. Be sure to reboot both your computer and router after making those changes.

I have moved your help request to our networking sub-forum where it is most suited. You can search the “Garuda Network Assistant” and our networking sub-forum for further information on any directions you are unsure of.

https://forum.garudalinux.org/search?q=RTL8192EU%20%23issues-assistance%3Awifi-ethernet-bt%20order%3Alatest

Again welcome to the Garuda community @Blorg001.

Blorg001 · December 31, 2024, 12:44pm

Thanks a lot! Now halfway done. For some reason Octopi couldn’t find the package from aur and so I installed pacseek. I also disabled all the rest of the repositories for now to avoid pending updates from screwing up installation. Pacseek did the job without any problems. I think it said during installation that it already blacklisted the aforementioned driver, but as that was nowhere to be found in the /etc/modprobe.d, I created /blacklist file there and added blacklist rtl8xxxu string there.

I’ll return to this by tomorrow.

Blorg001 · January 2, 2025, 10:01pm

Now as I returned to this I unfortunately found out that while pacseek finds the rtl8192eu-dkms file from the Aur, it just looks like installing it when the file is selected and I hit enter, but nothing actually happens and when I return to the pacseek, “installed” -field is still empty. Octopi or pacman fail to find the necessary driver file. Dependencies are ok.

tbg · January 2, 2025, 11:14pm

Use the paru command to install from the AUR. Octopi is currently not working to install packages from the AUR, and Pacman was never intended to install AUR packages.

Alternately, you could install a GUI package manager such as Bauh to install packages from the AUR.

Blorg001 · January 4, 2025, 11:23pm

Thanks a lot. Now it works correctly. Is it normal behavior for pacseek or paru to begin installing only when used with --skipreview option, as both got stuck to the end of the review and this was the only way I figured out to get the installation done?

BluishHumility · January 5, 2025, 5:30pm

No. I have never used that option. Really, you should get in the habit of reviewing the PKGBUILD before you install anything from the AUR.

If the PKGBUILD is longer than can fit on the terminal screen, it gets passed to the pager. In this case, you will need to press Q to exit the PKGBUILD review and proceed with the installation.

Blorg001 · January 5, 2025, 6:38pm

If the PKGBUILD is longer than can fit on the terminal screen, it gets passed to the pager. In this case, you will need to press Q to exit the PKGBUILD review and proceed with the installation.

I tried to find a solution from the command manual of paru as I didn’t figure out that. It would be nice if it said "press Q to proceed, instead of “END” - or actually I would like to have both. Thanks for your reply

BluishHumility · January 6, 2025, 4:11am

I agree actually, I think this would be nice. It has come up a fair many times that someone is “stuck” in the PKGBUILD review, because they are not familiar with using the pager and there aren’t any clues how to interact with it on the screen.

One thing we could do is change the prompt from a colon to a custom message, by setting the PARU_PAGER environment variable to use less with the -P flag (which allows a custom message in the prompt). I just gave this a shot on my machine and it works well.

Add this to your Fish config (~/.config/fish/config.fish):

# Hint to exit PKGBUILD review in Paru
set -x PARU_PAGER "less -P \"Press 'q' to exit the PKGBUILD review.\""

Then when you are in the PKGBUILD, that message will show as the prompt.

I’m thinking about adding this to the default Fish config, to maybe make it easier for folks getting started with Paru. What do you guys think?

Blorg001 · January 6, 2025, 11:39am

That’s nice. Of course I know it now, but for all the rest who get stuck with that and of course the devs who get one “stupid” question less to address - so definitely it should be there in the future releases if possible. Great job!
