I just recently bought a Tp-link Archer T6e Ac1300 network adapter which refuses to show up in the device manager / driver installer, all I get is a "network controller" under other devices.
Yes I tried installing both the utility and drivers, neither could detect the adapter.Hi, did you try downloading and installing the drivers? If not, I believe https://www.tp-link.com/uk/support/download/archer-t6e/#Driver should help you out.
I've tried every PCI lane, it does detect that theres a network controller how ever thats not enough for the drivers to install, Windows does find drivers for the device but it takes to long to install and ends up timing out .Have you looked for any hardware issues? Since the adapter is a PCI card, have you tried using different PCI lanes in your PC or a friend's PC to see if your adapter is faulty and/or your PCI lanes are faulty?
