[SOLVED]iwd.service & NetworkManager-wait-online.service fail to start

Hi, since the lastest update (2022-01-21) the wireless on my laptop refuses to start, or rather it will inconsistenly appear for a second then dissapear from de DE entirely, as if it never exsited.
So far i found out that both iwd.service and NetworkManager-wait-online.service are having problems starting either after a normal boot or (in the rare cases it manages to grab a wireless connection) after coming form sleep.

But still, i would like it if it didn't fail at all.
Read all i could about the subject but i'm not sure whats actually causing the problem, would be grateful for some guidence/ advice (where to read, what does/means what and why isn't it doing it the same way as before) so i can fix it. Thank you.

Re: [SOLVED]iwd.service & NetworkManager-wait-online.service fail to start

It means you do not want 2 network management services enabled at the same time.

NetworkManager want to use wpa_supplicant for wifi by default. If that's what you want disable IWD.

If you would like you can use IWD as the backend, hence the link, but you still need to disable IWD.

Unless, of course, you want to use just IWD. In that case you need to disable NetworkManager.

Re: [SOLVED]iwd.service & NetworkManager-wait-online.service fail to start

Super clear, didn´t know these services excluded each other, i do remember setting up NetworkManager during install, but after the update i saw iwd and thougnt it was part of it or something. Now i know better.
Disabling IWD fixed the issue, thank you so much.
