[Solved] Dual wireless interface

[hbarbosa]

Hi everyone, I have a problem when try to setup 2 wireless interfaces. I use a laptop and it have a wireless device already but I can't use software like Aircrack-ng because that device dont support promiscuous mode so a friend of mine got me an USB wireless device that supports that mode, however when I try to setup the device I cant use it, I alredy installed the drivers(followed this: https://github.com/nlkguy/archer-t2u-plus-linux) but the computer detects that the device exists but I cannot use it. I have searched for some stuff and I found the command inxi -Fxz and in the output I can confirm that the system identifies the USB device as wireless device but I cannot mount it our something like that. Do someone know what am I doing wrong?
I'm using Linux Mint.
the output of inxi:

yes it can see your Usb wi-fi but it has not installed any drivers, TPlink use realtek chipsets to install the correct ones you need to know which chipset is installed.
if i plug my tp-link in and run inxi , this is what i get

Network:
Device-1: Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet
driver: r8169
Device-2: Realtek RTL8192CU 802.11n WLAN Adapter type: USB
driver: rtl8192cu

Now when you installed Mint did you tick the box to install non free drivers ? [this saves a lot of time]
so we will now try additional drivers from the mint repositoty..
plug in the usb dongle..open menu go to all applications, scroll down to Driver manager, click on , enter password, and let it run
it will check all your hardware, if it finds a suitable driver for your dongle you can activate it from the driver manager , if not then you will need to find which chipset it has

Another thought.. upgrading the kernel from 5.4.* to say 5.11.* may help

I've tryed to update my system and when I go to driver manager I only get the drivers to the GPU. I have a TP-link AC600 and the chipset is this: Realtek RTL8821AU Chipset
Print driver manager:

I'm still learning a ton of stuff about linux and so on and when I followed this https://github.com/nlkguy/archer-t2u-plus-linux I thought I was installing the driver and when I made sudo make dkms_install it would connect to the USB wi-fi

yep its a well known problem, no quick fix, try this

Download Realtek RTL8821AU Wireless USB Adapter Driver 1030.6.1201.2015 for Windows 10
