I've got trouble with embedded Wi-Fi on old HP laptop WiFi hard blocked on HP 15-ac002ur on Ubuntu 20.04 and nothing helps and could not solve it so I've bought Wi-Fi USB stick D-Link DWA-131 but got trouble with it too.
Wi-Fi USB stick is recognized:

Tried nmcli radio wifi on - same thing.
Tried to create connection, but nmcli shows that device is not available:
[08:18]dmitriy@dmitriy-HP-Notebook[~]$ nmcli connection up "Wi-Fi connection 1" ifname wlx180f7609dcde
Error: Connection activation failed: Connection 'Wi-Fi connection 1' is not available on device wlx180f7609dcde because device is not available
Tried to access without NetworkManager (disabled it with systemctl) manually with wpa supplicant, it shows (I'm sure that password is correct):
[08:13]dmitriy@dmitriy-HP-Notebook[~]$ sudo wpa_supplicant -i wlx180f7609dcde -c wpa-2.conf

So seems that I'm close to solution but don't know how to make final step.
Could anybody help?
