"enable" is not a command. https://wiki.archlinux.org/title/Systemd#Using_units

Yup. And?

There is no command "enable". You seem to be missing the actual command systemctl. Please recheck the wiki for instructions.

If you won't read the wiki or man pages, Arch is going to be a very bad experience for you.

So you abandoned https://bbs.archlinux.org/viewtopic.php?id=281668

Also the OP "Last edited by shilmaz (Today 17:13)" and it *now* says

sudo systemctl enable NetworkManager.service
but it shows no output

@shilmaz, the problem remains: you're enabling the service, but that doesn't immediately start it.
Also I don't believe the "no output" part, because it'd print that a symlink has been created.

Read the wiki that Scimmia linked in #2

Next up: read https://wiki.archlinux.org/title/NetworkManager - eg. https://wiki.archlinux.org/title/Networ … i_examples
Even starting NM will not automagically get you somerandom™ wifi carrier.

Please be precise. While that is also not a proper command, I am quite sure it showed some output. Specifically, it should have returned:

Unknown command verb NetworkManager.service.

Also note that in most cases, actually showing no output is a sign that the command was successful (e.g. in your previous mention of `ip link set <interface> up`, that returned no output because that was a valid command that worked).

If your systemctl command actually returned no output, then perhaps you typed it properly in the terminal and quoted it incorrectly here (edit: it seems this is the case based on edits above). In which case you would have succesfully enabled the service - but enabling and starting are two different things. The difference between these two is covered in the wiki pages you've been directed to.
