[SOLVED] NetworkManager doesn't connect Wifi at boot

Hi all,
I am again here with a new problem.

I setup my arch box to boot into console where i login and do startx to open DE.

The problem is, NetworkManager doesn't connect to WiFi on boot.
However it is working absolutely fine under DE (KDE). As soon as DE opens, KdeWallet ask for password and then WiFi connected.

But i want to connect to WiFi in console (without X). It is quite annoying to fire DE just to do a wget.

I checked, NetworkManager service is enabled and running.
Here is output of different commands that may help

dmesg | grep wlp3s0

LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.

30 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.

Can someone guide me?

I haven't hit that particular use case yet but would the nmcli command be of some help?

Thanks davidm. I have seen that link. But with that i have to do it manually.

As NetworkMangager already saved WiFi connection profile, so can't it use it to auto connect at boot.

On my previous Debian box, it was connecting to wifi at boot without loading X. There was no such issue.
Can't i get same behavior.

Re: [SOLVED] NetworkManager doesn't connect Wifi at boot

dmesg | grep wlp3s0

[    5.798296] iwlwifi 0000:03:00.0 wlp3s0: renamed from wlan0
[    9.970511] IPv6: ADDRCONF(NETDEV_UP): wlp3s0: link is not ready
[    9.970615] bridge-wlp3s0: device is wireless, enabling SMAC

[    9.970645] bridge-wlp3s0: disabling the bridge
[    9.983966] bridge-wlp3s0: down
[    9.983972] bridge-wlp3s0: detached

Here wlp3s0 interface is made up then again made down.
I couldn't understand the reason for it, as there is no any other network service is running except NetworkManager.

Also it looks that NetworkManager is never trying to connect WiFi during boot as i couldn't find any log entry for that.

Re: [SOLVED] NetworkManager doesn't connect Wifi at boot

Hi since no one else was able to help yet I will share this which I see from the Wiki:

Once the NetworkManager daemon is started, it will automatically connect to any available "system connections" that have already been configured. Any "user connections" or unconfigured connections will need nmcli or an applet to configure and connect.

Do you have system level connections defined with the necessary keys as opposed to just user connections?  Sorry I don't have specifics as on my laptop I always just used the kde applet and my desktop is wired.

edit: to add if you have the authentication info stored in your wallet I don't think networkmanager has any way to get to it until you start KDE.  I could be wrong.  Look for another way to define it at the system level perhaps?  Just a guess.

Yes that's the reason. After going through wiki i found that, in order to auto-connect wifi in console i have to put password in connection profile.
But that's not a good practice.

So i ended up by writing a custom script which just accept ESSID and Password and connect it using nmcli.
I can directly call nmcli but i am poor on memory and may not remember command for long

Anyways, thank you @davidm for pointing me to right direction.
