problems with realtek 8811CU wireless lan 802.11ac USB NIC drivers - User:21/42/3929 - Feb 7, 2024

I'm having problems with the drivers on Kali Linux for my wireless dongle. The problem is running this command: sudo airodump-ng wlan0. I have already configured everything as wlan0 as Mon but the command still doesn't print any wifi networks around me, they are present, I think the problem is the age of the stick and I imagine that the drivers have no longer been updated. link of the drivers I downloaded: https: //github.com/brektrou/rtl8821CU. git. Thanks in advance

Realtek WiFi adapters don't have good support for monitor mode or Linux. This probably isn't huge news to you as you've had to install a random out-of-band driver. That chipset in particular may be flaky. It's USB3, right? dmesg may show some useful information.

are you sure its wlan0, try Wlan1

you may have to initialize the out of band drive with

modprobe rtl88

then start the modern mode

I'll counter with
Code
lsmod | grep 8821cu.ko
Also run uname -r and make sure that you're running Linux < 6.
