Dear Fedi, I have another question.

I've noticed some time ago that most of my Linux devices have two IP addresses in my local network, on a single wlan interface (192.168.1.127 and 192.168.1.128 in this screenshot)

Both of them work - I can ping those addresses from another device in a local network.

Why is that so? Why two addresses for one network interface? And how?

Looks like an alias has been assigned. Normally that only happens if you make a static configuration. Maybe double configured or typo in network mask? Does the issue remain after a reboot?

@kuba
Static configuration or using DHCP?

    Run it with 'status' to see the status.

    If it helps, a cheat sheet for systemctl: https://linux-audit.com/cheat-sheets/systemctl/
