Issues with TP Link AC1300 Archer T4U (2)

I had an issue with the dongle not getting recognized at all. After installing some drivers from github, now it is actually recognized, and even the WiFi icon in the top-right menu appears (without a name) and it fails to find any networks.

When I run

sudo lshw -C network

it finds the dongle, but it says *-network DISABLED

I've disabled Secureboot and it's UEFI, if that makes any difference. Someone knows how this issue can be handled?

rfkill list all results:

3: phy3: Wireless LAN
     Soft blocked: no
     Hard blocked: no
