Sadly I made the mistake of not checking decent Linux support before buying.
Anyways, my 2 cents, lsub should show which drivers to use - apparently tp-link change internals without changing the model number.

Always check the hardware info as it is the chip that matters. Sometimes the chip will even be a different vendor or as in your case a different version.
I feel like i did’t explain the problem clearly enough.
i have tried to download all those drivers in many of the ways i’ve been suggested to.
The problems seems to be that the drivers only work up to a certain linux kernel version., as the error shown after tried to install any of them seems to suggest:

Okay…you have shown 3 different packages all not working? Are you running on the lts kernel or some other? Or are you not running the package install correctly?
I believe i just have to accept the “linux compatible” usb wireless adapter i just bought doesnt work.
Even the oficial Tp-link webpage show drivers avaliable only up to 4.10
anyways, heres my linux kernel.

So it seems there is some reason why it’s not working. It’s very strange to me as i have a lot of Tp-link WiFi cards but they are internal Pci-E cards and they use Broadcom chips.
Your kernel is 5.15.10, and your headers are 5.15.11.
linux 5.15.10.arch1-1
linux-headers 5.15.11.arch2-1
I don’t know what you’ve been doing to achieve that partial upgrade state, but UPDATE YOUR SYSTEM, reboot, and try building the package again; when yay asks you to for “packages to cleanbuild,” type A (for “All”) just in case.
EDIT - I missed that you also have the LTS kernel - you’ll probably want to install the linux-lts-headers package.
