Hi
What I have found to work is to use the WPS button feature - push button on both and it connects
You mean this:

To be honest I’m not owner of an router which would support this kind of feature so cannot share any experience with you but from my point of view it looks like a router issue and not like WLan card issue….
Are you able to connect your notebook to another Wlan in your environment?
Maybe you should check the manual or your router and should disable this WPS in orer to check if its possible to connect the notebook to your router…
You could also test the connection with “open WLan” but this should be done only for testing purposes…
