Wifi connection disabled

I have installed Manjaro - “manjaro-xfce-21.0.7-210614-linux510” recently in my HP - 250 G3 laptop.
I haven’t installed any additional drivers. It’s just clean Manjaro system with default options and newest kernel.
I can’t enable Wifi. The Wifi checkbox is unclickable.
I have tried to plug USB Wifi adapter, but the results were poor. The Wifi connection still did not exist.
Is there any chance to get internal network card to work properly? If it’s impossible, could you help me to establish connection using usb Wifi dongle?

USB network adapter: TP-LINK TL-WN722N v.1 (Atheros AR9271)
Internal network adapter: Ralink RT3290

Here are the outputs of a few commands (USB adapter plugged in, without ethernet connection):

After I press F12 something changes. It might be some issue with F12/airplane mode button, but it doesn’t help anything.>

sudo dmesg | grep iwlwifi
Nothing found…

Is the device enabled in BIOS?
Is there a hardware button to toggle its status?

The only option I found in BIOS is Internal Adapter Network Boot. I switched from disabled to enabled. It did not help. Network Card is still hard locked.

There’s no dedicated hardware button other than F12 function key in this laptop to toggle network card status.
As I wrote, function key F12 toggles status from soft blocked to soft unblocked, but it remains hard blocked.

I’ve managed to get external usb card to work.
I blocked Ralink internal card module, by adding line: “blacklist rt2800pci” to the file /etc/blacklist.conf
Internal network card drivers seems to block usb adapter. Now, once internal card is blacklisted TP-LINK TL-WN722N works just fine! I’m happy with this result. Internal card Ralink RT3290 seems not to work no matter what and the only option is to replace it with other card.
At least I have wireless internet connection now.
