Cannot Get My tp-link AC1300 (Archer T3U) Wireless Adapter to Work

I have been looking for a couple of days for information on getting my tp-link AC1300 (Archer T3U) working. I have the drivers installed (i hope they are the right ones) but it is not recognized as a wireless connection.

Here is what I’m working with:

It appears that the device is recognized:

But it is not recognized as a network connection:

I have searched the internet over (including this forum) and have found similar problems but nothing that gives me a working solution.

Thanks in advance for any assistance.

What one driver you installed?

According to your model, it should be rtl88x2bu-dkms-git from AUR.

Yes, that’s the one. Sorry, I should have included that detail in the original post.

  1. headers installed? (needed for driver compilation)
pamac install linux519-headers
  1. driver loaded?
lsusb -vt

I was not aware that this was needed. I thought that installing drivers and restarting would be enough. After following your instructions all is working as advertised.

I guess I still have a lot to learn, especially when it comes to the networking aspects of Linux.

Thank you for the assist.

Which is weird beacuse if you don’t have the headers installed, it should have complained about that during the installation of the driver.

I didn’t notice any complaints, but maybe I just wasn’t paying attention. :man_shrugging:
