[SOLVED] RTL8821CU not working

Hi I'm trying to use my "TP-Link AC600 wireless Realtek RTL8811AU [Archer T2U Nano]" USB WiFi module on my pc but I couldn't figure out how to actually get the driver to recognize my USB WiFi... I'm also sure that this was working fine on linux since I remember using it on Manjaro like a year ago. I really don't know how stuff works on linux since I'm a newbie but here's some stuff that I think is useful for troubleshooting?

$ uname -r
6.0.6-arch1-1

$ lsusb
Bus 002 Device 002: ID 0480:0900 Toshiba America Inc MQ04UBF100
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 005: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)
Bus 001 Device 004: ID 046d:c092 Logitech, Inc. G102/G203 LIGHTSYNC Gaming Mouse
Bus 001 Device 003: ID 09da:2268 A4Tech Co., Ltd. USB Keyboard
Bus 001 Device 002: ID 05c6:9024 Qualcomm, Inc. Android
Bus 001 Device 007: ID 2357:011e TP-Link AC600 wireless Realtek RTL8811AU [Archer T2U Nano]
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

$ sudo dkms status
[sudo] password for evonestel:
rtl8821cu/5.8.1.7.55.6d03eb2, 6.0.6-arch1-1, x86_64: installed

I tried pretty much anything I can find on the internet but they never worked... Hopefully these will be enough for troubleshooting. Also sorry for any grammar mistakes etc. since my main language is not English.

I already have this installed but it's not working.

I realized I misread the package you gave me but it works now! I uninstalled the morrownr one and this one is working. Thanks so much!!

Re: [SOLVED] RTL8821CU not working

That's neither in your dkms output nor in the journal.
You seem to rather have one of https://aur.archlinux.org/packages?O=0& … &submit=Go ?

Edit: too late

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
