Default support for rtl8192eu - is it possible?

What would be required to include rtl8192eu wifi driver in Fedora?

I have an adaptor, TP-Link TL-WN821N v5/v6 [RTL8192EU] driver: rtl8xxxu

But it does not work OOTB with Fedora (I swear it did once on my wife’s Fedora, around 6.14).

Why is the device calling rtl8xxxu driver when it doesn’t work?

The best way to install this device is via GitHub - clnhub/rtl8192eu-linux: Realtek rtl8192eu official Linux driver, versions: 5.2.19.1 (master), 5.6.3.1, 5.6.4 and 5.11.2.1 (default) but that does not work with the F43 testing kernel 6.17.1 that is current at this time.

I am on Sway WM and installed via Everything NetInstall with a Custom Minimal selection.

Realtek is not really collaborating with the linux kernel. That’s why it is so messy with them.
Just some coments about them I found in (Reddit):
Are realtek wifi cards unique with poor Linux?

Topics as above propose to replace Realtek with Intel. Unfortunately this just works with internal wifi cards.

I feel your pain, Intel is kinda the gold standard when it comes to Linux wireless but they don’t make a USB chipset.

Explain?, it compiles ok.

You’re on 6.17, I’m on 6.17.1

7

That shouldn’t make any difference, it a release kernel so there shouldn’t be any major changes

8

I’ll give it another go then.

It compiles on the newer kernel

I got the rtl8192eu driver to build.

I think my problem was that I followed the instructions on the github site which has the command for installing C development tools with DNF4.
So I installed them with the commands sudo dnf install @c-development and sudo dnf install @development-tools

I now have the USB adaptor using the rtl8192eu driver, as seen with inxi -N however I still can’t get the adaptor to pick up wifi signal with nmcli dev wifi list and yes I made sure the radio is on with nmcli radio wifi on

When I run lspci no wireless controllers show up.

lshw shows

Edit: I enabled the device with sudo ifconfig wlp3s0f3u1 up yet the wifi still doesn’t work.

Can you post

I have followed Vlad’s commands, and am in almost the same position.

Ran all the test command again after reboot - all the same except

/var/lib/dkms/mok.pub is not enrolled

Which I assume is as I don’t have secure boot enabled.

Finally made it work.
I was a victim of my own minimalism :slight_smile:
As I have a ‘custom’ install from the Everything NetInstall, running Sway, I did not have NetworkManager-wifi installed.
I installed it and rebooted, now my wifi works. Thanks to Nmtui <Radio> Wi-Fi Hardware: Missing - #8 by scottro - Rocky Linux Help & Support - Rocky Linux Forum
But also big thanks to Leigh and Vlad for helping me get there.

This happened to me with KDE Plasma too.

The subtlety is that if you’d chosen “Sway Desktop” from the environments on the left-hand side of the selector screen, you would have got networkmanager-submodules, which includes NetworkManager-wifi.

But if instead you select “Fedora Custom Operating System” on the left, then the Sway groups on the right, you don’t get networkmanager-submodules without explicitly selecting it.

The upside is I get to learn what goes into a full desktop edition, without the bloatware.
The main reason I don’t go for the Sway Spin, is the background pic and the menu.
This is only the second problem I’ve had with the minimal Sway in about two years.
