Unable to connect to wifi with tp-link AC600

Hello everyone!
Today we bought a customized gaming PC tower with Windows 10.
We also got a TP-Link AC600 Archer T2U WiFi adapter.
Unfortunately, we can't connect to the WiFi...
The PC detected a few networks (except ours!), and after a few restarts, our box (SFR) started to appear among the networks...
However, despite several attempts, it won't connect. The network is detected, but when we enter the password, it says the connection could not be established.
When connecting the PC directly to the box via an ethernet cable, the internet works fine.

A few additional details:
- Our box is visible and works from our phones + our 2 laptops
- Windows update is up to date
- The WiFi adapter driver is up to date
- Sometimes the adapter seems to "deactivate" from the PC after an attempt, as if it is no longer plugged in via USB

Do you have any ideas to help us connect to the WiFi? What do you think is blocking it?
Thank you very much for your help!!

Have a good evening (or good night) everyone!

    We finally found the solution! Some USB ports are 3.0 and others are 2.0
    It was enough to plug the wifi stick into a 2.0 port :-)
    I'm posting the solution in case someone encounters the same problem!
    Thanks anyway!

      It's easily recognizable though...
      it's blue on blue instead of blue on black, although both work.
      Maybe we should mention it more often, apparently, some people still don’t know.
      USB blue == 3.0
      USB black == 1 or another but less than 3.0 although, they’ve now invented 3.1 gen1 :-(
      USB-C == 3.1 or 3.1 gen2
      However, putting a USB 3.0 adapter on a 2.0 port shouldn’t prevent it from finding Wi-Fi networks, it might just reduce the maximum speed.
      And the reverse even less....
      There's something unusual about this motherboard.
      In short, it doesn't seem like THE solution to me, even if it works for you, good for you, but it's not very reliable anyway.

    Hi,
    try another type of wifi adapter with more powerful external antennas maybe.
    Otherwise, on a tower,
    keeping the ethernet cable is perfect too.

    and ... There you go!

      Hello
      Thank you for your response. Unfortunately, even when the computer tower is close to the box, it detects it well but the connection doesn't work...
      Ideally, it would indeed be to stay on Ethernet cable, but we cannot technically (the tower is on the first floor).
      Thank you very much!

        It is always possible to run an Ethernet cable upstairs.
        Some are very discreet.

        And it should also be possible to use a Wi-Fi key designed for that purpose...

        we don’t say wifi key, but wifi/usb adapter to avoid confusion with the WPA key which is the password for the wifi network.
