Why my wifi only works on instalation phase

The kernel of instalation interface is 5.17.1. If I click to set by default r8168 or r8169, it works anyway, but only on this instalation phase. When my Endeavour is complete to use, even if I change from r8168 to ~~~69 it doesn’t work. So I tried to change my kernel but I don’t know how to install this specific one. On 5.15 and 5.18 it doesn’t work simply and I’m trying it for hours. If my problem is not the kernel and not change 68 for 69 and vice versa, then what it is? Work like a charm on instalation phase with this kernel.

The drive that is missing is R8188eus, with S in the end. Where to find these?

Can you run the following command from terminal so we can know your hardware configuration:

inxi -Fxxc0z --no-host

I was checking the Arch forum and it looks like the newest driver might be broken for the Realtek RTL8188EUS.

Then why it works normally on the instalation phase? That’s weird.

My guess is the install setup used an older driver. Then when the install starts downloading and setting up the OS it upgrades to the latest.

@pebcak

Whats the best way to downgrade the wifi driver since its from the AUR?

Is there a way to change my kernel to that used on the install setup (5.17.1)? If so, can you teach me so I could try it? Sorry for bothering. Waiting @pebcak help!

If I am not mistaken, you could change the pkgver= in the PKGBUILD to point to another version.
However, in this case I don’t know which version it should be. I can’t see in the Github page. I guess you could just uninstall 8188eu-dkms for the kernel module to be used instead.

Also, in the Arch Forum post you linked to, the OP seems to have solved the issue by installing 8188eu-dkms-git.

I would not downgrade your kernel yet. I mainly use laptops so i tend to use the latest LTS with a patched driver.

Last week I installed a TP-Link Archer T3U USB wifi on my wifes laptop. The latest stable kernel powered the usb wifi but at very low speeds. So I switched her to the LTS kernel and patched driver. Now shes all happy.

This is the documentation i am reading:

I tend to be in the Arch wiki allot.

I simply tried 8188eu-dkms-git and it worked. This is my third day attempting to fix this issues on Arch distros, haha. Thanks you both, i’m very happy now.

It takes patience and research to iron out wrinkles. I tend to come to the forums here so i can get pointed in the right direction. Glad your all fixed.I find it rewarding when i get to learn.

Glad you got it resolved!
Credit where credit is due, you might want to consider to mark @kagetora13’s post pointing to the Arch Forums’ post as the solution.

Also, welcome to EnOS’ community @pierrelatour!

The driver should rtl8188eu … currently.

r8188eu is a USB driver for RTL8188EU devices. It’s going to be replaced by rtl8xxxu.
