Realtek RTL8811AU Wifi not working (TP-Link AC600)

Issues & Assistance Networking Support
1

Hi, I am a very new user to both arch linux as well as Garuda KDE I have switched from windows to here hence have zero knowledge about how things work around here. As the title suggest i have been trying to make my Wi-Fi adapter (Archer T2U Nano) getting run on the system but have been unable to do so after trying most of the top solutions over the web such as installing Realtek wifi adapters and downgrading my kernel but i run into some problem no matter what i try. Without this driver i wont be able to update the system through the assistant so if you can please help me out ASAP , really grateful to you for having read this and please forgive any of my mistake done unintentionally.
Thank you.

Welcome to the Garuda community @misky500.

There is a post on our forum dealing with your WiFi chip. Install the driver suggested in this link:

I hope this is help full even a little bit even though might not concern what you are specifically looking for

I find using nmcli to play around with this wifi/network stuff more effective and easy e.g

nmcli device connect <adapter>

nmcli -h

Thanks for trying to assist @Yada.

Unfortunately, this user appears to be using a Realtek WiFi chip with an out-of-kernel driver. Until the user installs the correct driver they will likely not be able to connect to WiFi no matter which method they use.

Thanks a lot to help me out, but it is not a realtek wifi chio its a tp link wifi adapter

pacman -S rtl88xxau-aircrack-dkms-git
it’s a package, not a command.

The brand of the USB WiFi stick (TP Link)is irrelevant. It is 100% about which manufacturer produced the actual wifi chip inside.

WiFi manufacturers often change the WiFi chips they use inside the WiFi devices they produce. The model number TP-Link AC600 is not the deciding factor in which driver you may need to install. This is because the WiFi chips inside are often changed over time if the model is sold for a fair number of years. The relevant information from your inxi output is Realtek RTL8811AU, as this is the actual WiFi chip inside the USB WiFi dongle you purchased. The chip determines the driver you require. This is why I recommended you install the rtl88xxau-aircrack-dkms-git driver as it covers your Realtek wifi chip, (as well as other similar Realtek chips). You never want to install the driver from the TP Link website. You should always attempt to locate your WiFi chip’s driver at the AUR or Chaotic AUR repositories first.

I hope you don’t mind, I am going to amend your thread title and location to make it easier for others using your WiFi chip to find a solution.

Glad I could help you locate the correct driver to get your wifi up and running. :+1:

Sorry, the solution was to install the driver and not how to do this correctly in the terminal.
So I refer to the correct post and have marked it.

Thanks a lot sir my most humble respect to you for helping such a trashbag dumbo like me, I am loving Garuda linux because of all you guys really appreciate the support :))

LOL no need for self deprecation, no one was born learned.
Would you believe, the first time I read that shift left would multiply by two, I thought my keyboard was broken?

Again, welcome to the Garuda community @misky500. I’m sure you’ll enjoy your time here.
