[SOLVED!] T6E Wi-Fi card does not work with Sierra 10.12.5

I installed the TP-Link Archer T6E wi-fi card, however, I can't make it work, even after trying a fix I found in this forum. I can still connect thru Ethernet though, but I don't want to stay tied to wired connection all the time.

However, when I boot in the recovery partition and browse the net with the built-in Safari browser the T6E connects flawlessly to the wireless router.

Update: SOLVED!!!!...
