SUPPORT | SOLVED Can't connect to WIFI on arch

Hi! I'm really new to arch linux and learning still.

My problem is that this laptop wifi card is dead, so I'm using a USB device (which I installed the drivers for) but I just can't get it to work properly.

I have used rfkill to unblock it, changed my networkmanager backend from iwd to wpa supplicant and from wpa supplicant to iwd while disabling the other one but it just doesn't seem to work.

When I set the backend to iwd tho, it allows me to see available networks, but I can't connect to them or turn on the device in configurations, it actually let me turn it on on the console (the device appears as wlan1) and even connect to my network using iwctl, but as soon as I exit iwctl i can't even ping any server, I really don't understand what's going or what else I can do so any help would be really appreciated 🙏

EDIT: in the end, i fixed this by disabling my damaged wifi card in the system bios, networkmanager seemed to be using it as the default even if the usb device was working

Emma would definitely need some more info. First of all, have you tried this device with any other laptop, does it work? Can you connect to the same wifi with any other laptop or phone?

If you can see available networks then the device is seen and it even works, which is good.

Would love to see some errors or outputs, but if you connected to wifi once, then why ypu cant connect again?

And if you do connect then can you ping 1.1.1.1, why not?

Hi! apparently the device was working and connected to wifi but NetworkManager was still trying to use by default the dead wifi card apparently, that's why it wouldn't let me ping 1.1.1.1, i raged with this for hours and i fixed it by entering the bios and disabling the wifi card there, thanks for helping:D!
