Module for rtl8188eus wifi adapter not working properly

[YSt]

After 3 modules for the wifi adapter rtl8192eu failed one after another in the course of 1 year, and they just won’t even get installed on my system anymore, I found another wifi adapter with different chip rtl8188eus. Installed the corresponding module listed as number three on this page
https://aur.archlinux.org/packages?K=8188EU&SB=p
using the following commands:

* git clone https://aur.archlinux.org/8188eu-dkms.git
* cd 8188eu-dkms
* makepkg -si
* echo -e “8188eu\n\nloop” | sudo tee /etc/modules
* sudo grub-mkconfig -o /boot/grub/grub.cfg
* sudo mkinitcpio -p linux

It is kind of working, max internet speed is 2 Mbit/s out of possible 8 Mbit/s. Sometimes it is working, but then speed drops to almost zero.

I don’t know what I did wrong? Maybe there is something else needs to be done? maybe blacklist some module?

Please post some systeminfo.

At the least: inxi -aN

Hopefully this will give forum members some ideas.

Also, out of curiosity, what is your intention with the following line?

@YSt

echo -e “8188eu\n\nloop” | sudo tee /etc/modules

$ inxi -aN

I don’t know. When I installed first driver for another wifi adapter there was this code that I found on some internet forum. there one person used it to install the same module for the same wifi adapter. I thought it was necessary. I did not question the wisdom of this person, because his code worked at that time.

Have you tried just installing a package from the AUR using yay?
This is the standalone driver for that chip.

https://aur.archlinux.org/packages/8188eu-dkms-git

yay -S 8188eu-dkms-git

Installed:

$ dkms status
8188eu/5.2.2.4.r826.f435a10, 6.3.2-arch1-1, x86_64: installed

Rebooted the PC.
Speedtest proudly shows 0.89 Mbps.
I don’t think the problem is solved.
Are all wifi adapters with realtek chips this bad?

I would try to boot with the lts kernel. For kernel 6.3, rtl8188eu chips are supported by the rtl8xxxu driver.

I bought an Atheros AR9172 wifi adapter. It works with the default driver. No need to install anything.
