[Solved] Can't connecto to wifi using NetworkManager

LudaOtaku · 2014-08-15 18:28:59

Hello,

for some reasons, I can't connect to my WiFi network using NetworkManager. What's weird, is that my network and all the other networks around coming from my neighbours' houses are displayed, but I can't connect to any of them, including mine...

The wired connection works just fine (that's why I'm able to post this message), but I can't get the wireless one to work. NetworkManager is configured to use dhcpcd for dhcp by the way.

When I try to connect I usually don't get any notifications, but if I press several times the connect button this will be displayed

Typing systemctl --type=service outputs this.

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.

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

I know my wireless chip works fine because this computer could connect to network with arch previously.

Any idea what the problem could be? Do not hesitate to ask for more information. I just didn't post a lot because I didn't know which ones would be useful

Thanks

Are you sure that your configuration for the network is still correct? I noticed that a few days ago networkmanager didn't connect to a network because it somehow lost the password.

LudaOtaku · 2014-08-15 20:43:02

I clicked on "Forget this network" and tried to reconnect like 10 times now. I tried to connect to another wifi, but in both cases there's no dialog asking me for a password. I just click on my wifi's name, and... Nothing happens.

Reguarding the configuration itself, well I don't remember doing anything special when I installed NetworkManager six month ago on this same laptopt (I had to reinstall it).

runical · 2014-08-15 21:13:58

Ok, so networkmanager did not accidentily forget the password.

Can you post the output of:

systemctl -u NetworkManager -b

This shows the log of networkmanager since this boot. Might be something intersting there.

If it's a secured network, you would have had to input a password at some point. Is it possible the network settings have changed (e.g. it used to be an open network, but now is secured)?

Jeroen)Mathon · 2014-08-15 21:39:18

For me and my friend it did not display a dialog to enter the password.
As a work around got to the applet select "Network Connections"
Select your network SSID and then go to Wireless security.
Then enter your password.

LudaOtaku · 2014-08-15 23:28:00

runical : Are you sure your command is correct?

[ludaota@ludarch ~]$ systemctl -u NetworkManager -b
systemctl: invalid option -- 'u'

Trilby : Nope, this network has always been secured. And I already connected to this network using this computer prior to my arch reinstall and it worked. Just fine.

Jeroen)Mathon : Wow, I feel so stupid now, that actually worked, I should've tried this before... Thank you!

My question now is... Why's NetworkManager not opening a prompt to ask me for the password?...

Whoops, that was supposed to be

journalctl -u NetworkManager -b

You are using gnome, right? Is there anything else that doesn't give a dialog as it is supposed to?

scryan · 2014-08-16 05:33:41

I have had this issue as well, where you are never prompted for a password, so it will not connect.
For me it DID work if I manually went in and edited the security settings.

I have always fixed it by installing gnome-keyring, and that gives me the password dialog, though I don't know if this is the correct answer or if there is a better way. (hopefully someone will let us know if there is a better way?)

LudaOtaku · 2014-09-04 14:07:34

Installing gnome-keyring fixed the problem. Thanks!
