[Solved] Establishing a wireless internet connection

Hi there,

unfortunately I encounter some trouble establishing a wireless internet connction.

Netctl gets me the following output.

[root@CANB002 ~]# netctl start wireless-unibude

This is the corresponding netctl profile:

After that attemt had failed, I decided to try setting up the connection manually. Bringing up the wireless device seems to work fine as I get a satisfying response on my network scan.

That should denote that my network driver is working fine so far, shouldn't it? However I created a wpa_supplicant configuration file using wpa_passphrase and startet the wpa_supplicant, whitch lead to an error message saying some device is busy and an association request to a driver failed. So i figured that setting the driver flag for the wpa_supplicant would do the trick.

[root@CANB002 ~]# wpa_passphrase 001D73B3EA22 ############# >> /etc/wpa_supplicant/unibude.conf
[root@CANB002 ~]# wpa_supplicant -Dnl80211 -i wlp5s0 -c /etc/wpa_supplicant/unibude.conf

Et voilà! I'm connected to the internet. :-)

The question why I can't establish the same connection using netctl remains to be answered. I'm looking forward to your help.

Kind regards
Paul

Re: [Solved] Establishing a wireless internet connection

netctl isn't passing the needed arguments in its call to wpa_supplicant? Is there a way to control that?

EDIT: do you have any luck using the netctl-auto@<interface> service?

Re: [Solved] Establishing a wireless internet connection

No, the netctl-auto@<interface>.service doesn't work neither. It seems like it produces not the correct link.

[root@CAN002 ~]# systemctl enable netctl-auto@wlp5s0.service
ln -s '/usr/lib/systemd/system/netctl-auto@.service' '/etc/systemd/system/multi-user.target.wants/netctl-auto@wlp5s0.service'

Re: [Solved] Establishing a wireless internet connection

You can use the working wpa supplicant config together with netctl, see /etc/netctl/examples/wireless-wpa-config for more info.

I just tried that, but still doesn't work. journalctl gets me the following output.

Re: [Solved] Establishing a wireless internet connection

I tried to move the netctl config files to another directory and generate an new one using wifi-menu. The generated config file contains exactly the same information as my first config file wireless-unibude does. Just the order of the entrys varies slightly. Anyway I just tried it again using this config file and noticed, that the output of journalctl altered (dont even have a clue, why it did). To get you up to date, here is the current output from journalctl after trying to start the internetc connection using the config wireless-unibude or the newly generated wlp5s0-001D73B3EA22.

Re: [Solved] Establishing a wireless internet connection

this line seems most significant to me.

Jun 24 21:03:46 CANB002 network[4089]: WPA association/authentication failed for interface 'wlp5s0'

Are you sure your security settings are correct? Are you using a hex key? If you are, some special quoting rules apply. In addition, browsing through the man page for netctl.profile, there's an option for setting the WPADriver to use for a specific profile. I think I would try that with your original profile, or the wpa_supplicant one that you used. Sorry if I'm not much help.

Re: [Solved] Establishing a wireless internet connection

Thats embarrassing, you're damn right, I got the security settings messed up somehow. :-( The config files that aren't using the wpa_supplicant config are working fine now. :-)

Setting the WPADriver wouldn't do anything as the nl80211 is one of the standard drivers, by the way.

So, thank you very much for your help indeed.
