TP-Link Archer T3U AC1300

cannot find my wifi adapter using ip link command. It only shows the inbuilt wifi adapter.
Am using TP-Link Archer T3U AC1300 Mini Wireless MU-MIMO USB Adapter.

The lsusb output is:

not able to see my tplink usb wifi adapter in this

am a newbie Please help!!!!

Seems like it's picking up the device but you have no connectivity. I feel like this is my answer to everything at the moment, but try a different kernel, 5.3 or 4.19. Lots of people are having connectivity issues with the new 5.4 kernel (myself included, also using a tplink adaptor).

Out of curiosity, are you able to connect with the internal wifi adaptor?

Have you properly installed the driver?

Install kernel 4.19 or 5.3.

Install the kernel headers:

sudo pacman -S $(pacman -Qsq "^linux" | grep "^linux[0-9]*[-rt]*$" | awk '{print $1"-headers"}' ORS=' ')

Install the driver from AUR:
