[Realtek RTL8812BU] TP-Link Archer T3U Wi-Fi Adapter not working after Apollo Install

Hello, I just installed EndeavourOS Apollo XFCE but my Wifi Adapter (TP-Link Archer T3U AC1300) won’t find anything in the NetworkManager Applet.

I already tried the solution from this Topic Wi-Fi Adapter not working after Atlantis Neo Install which had worked before.

Did you get any error messages executing yay -S rtl88x2bu-dkms-git?

May I ask why did you do a fresh install?, did you run into troubles with your Atlantis installation?

Have you tried

yay -S rtl8822bu-dkms-git

I tried some other operating systems but at the end endeavour is still my favorite.

[orbital@orbital-m32cd ~]$ 

so the “atlantis” worked before? Do you still have that on a stick or have a copy of that .iso? If so, just install that and apply the fix you did before as an easy fix. Anything arch based is rolling so both the atlantis and apollo installs will update to the same system in the end, only difference is a couple of thing get automatically installed with apollo like firewalld, and not like firefox etc but any difference can be added/removed after atlantis named .iso.

Disable firwald and see if it works.

Yes the solutions I got from the forum worked on atlantis and I could use wifi connection but I don’t have the old iso anymore.

How do I turn the Firewall off?

shouldn't start on next boot, just remove it if you don't want it usual way.

It still doesn’t show me the wireless connections. :thinking:

you spell " firewalld " wrong

There is a new kernel now? So have you updated because the error showed no headers?

How do I update the Kernel?

You said the atlantis point release .iso worked for you and you could fix it from there? Is that not so then? (apollo installs firewalld by default, not atlantis, so you haven’t the atlantis .iso around?..)

Standard updating! What kernel is installed?

uname -a

What does your network show?

inxi -Na

Upadate now

sudo pacman -Syu

back then this was the solution:

yay -S rtl88x2bu-dkms-git 

and then everything worked.
