Couldn't connect to wifi using RTL88x2bu usb adapter

Hi,
I've just converted windows to garuda linux dragonize version and installed it with single boot.
I tried to connect my usb adapter but it didn't shows/recognize any network (No available connections).
I installed its driver through my CD rom (windows installation).
then, i opened up Garuda Network Assistant and clicked Windows drivers tab but it tells me theres no Ndiswrapper. here's the screenshot ;

btw i'm new to linux :frowning:

Do not use ext. files from CD.
In pamac

or in konsole

sudo pacman -Syu ndiswrapper

or

sudo pacman -Syu ndiswrapper-dkms

I am not sure which one for KDE.

and

:slight_smile:

idk what's going on but it shows these errors

No picture from terminal outputs.
If you include terminal outputs in your post please use the proper output format in your post. Using "~" 3 times above and "~" 3 times below the text block will provide a readable, raw look.

Images can be read worse, are not searchable and copyable for further search.
Should the helpers have to guess everything or laboriously type it in themselves?

Ndiswrapper is basically only for ancient wifi adapters. Anything produced in the last 10 years shouldn't really need to use an ancient Windows XP driver.

IMO If you need to use Ndiswrapper it's time to buy a new wifi dongle. I haven't had to us Ndiswrapper for more than a dozen years (I'd guess).

We need to know the manufacturers chip ID used in your wifi dongle. The commands below will help us identify your hardware so that we can assist you. Without it, there is really no way to help you.

Please post the outputs of these commands:

lsusb
inxi -Fxxxza

Run those commands from the live boot disk and post them to the forum. If your wifi is not working in the live environment then save the commands output to a text file on another flashdrive to post later.

Is your wifi working on the live disk?

The easiest method to upload the outputs is to either use an Ethernet connection or use "Android USB phone tethering". Search the quoted text online if you don't know what that is.

Please do not post pictures of text outputs. I am currently only using a cell and reading a pic is very difficult on my phone with a small screen and poor vision.

Please post all logs and terminal commands as text only. Please use three of these symbols ~ before and after any terminal outputs that you post. This ensures that the output is formatted correctly in a proper human readable code block on the forum.

Example:

Welcome to Garuda, looking forward to helping you once the outputs are posted.

You need
https://aur.archlinux.org/packages/rtl88x2bu-dkms-git/
This driver

To install it connect to internet via usb tethering then

pamac build rtl88x2bu-dkms-git

Then reboot

As @librewish already so kindly stated installing that driver should fix your issue.

If by chance it doesn't, then install the linux-lts kernel and test if your wifi is operational using the older kernel.
