[SOLVED] Netctl failing where sole wpa_supplicant works
Hello,
after having some difficulties I managed to set matters stright and got my Broadcom BCM43142 wireless card working. I prepared the following config:
$ cat /etc/wpa_supplicant/home.conf
network={
ssid="TP-LINK"
#psk="my_secret_passwd"
psk=.....
}So I run the following and in spite of reporting some problems, it works:
$ wpa_supplicwpa_supplicant -i wlp8s0 -c /etc/wpa_supplicant/gda.conf -Dwext &
Successfully initialized wpa_supplicant
ioctl[SIOCSIWENCODEEXT]: Invalid argument
ioctl[SIOCSIWENCODEEXT]: Invalid argument
wlp8s0: Trying to associate with e8:de:27:3d:fc:ae (SSID='TP-LINK' freq=2412 MHz)
ioctl[SIOCSIWFREQ]: Operation not supported
wlp8s0: Association request to the driver failed
wlp8s0: Associated with e8:de:27:3d:fc:ae
wlp8s0: WPA: Key negotiation completed with e8:de:27:3d:fc:ae [PTK=CCMP GTK=TKIP]
wlp8s0: CTRL-EVENT-CONNECTED - Connection to e8:de:27:3d:fc:ae completed [id=0 id_str=]Now, after running $ dhcpcd wlp8s0, network works fine. However It's annoying to have to type those commands every time I boot so I wanted to automate it using netctl just as I did with wired connection. So this is my netctl config:
$ cat /etc/netctl/home
Description='A wpa_supplicant configuration file based wireless connection'
Interface=wlp8s0
Connection=wireless
Security=wpa-config
WPAConfigFile='/etc/wpa_supplicant/home.conf'
WPADriver=wext
IP=dhcpNow I kill wpa_supplicant and run:
$ netctl start home
Job for netctl@home.service failed. See 'systemctl status netctl@home.service' and 'journalctl -xn' for details.
$ netctl status home

Re: [SOLVED] Netctl failing where sole wpa_supplicant works
Have you considered using Systemd-Networkd for this task? As you already know how to work with wpa_supplicant directly, setting up a wpa_supplicant@wlp8s0.service and systemd-networkd.service will save you the headache of having to debug netctl.

Re: [SOLVED] Netctl failing where sole wpa_supplicant works
I'm new to Arch, so I don't yet know well wich tools can be used for what and how to configure system services. But I'll explore the subject then. Thanks for your tip.

Re: [SOLVED] Netctl failing where sole wpa_supplicant works
Yes go through the systemd-networkd Wiki page, and for wireless setup follow this thread:
https://bbs.archlinux.org/viewtopic.php?id=178625
This is what I do for wireless conneciton on my laptop:
First of all /etc/systemd/network/10-wireless.network (the name of the file doesn't matter, just make sure it has a .network extension):
[Match]
Name=wlp18s0
[Network]
DHCP=yesThe /etc/wpa_supplicant/wpa_supplicant-wlp18s0.conf file (replace wlp18s0 with your wireless interface name).
Now, enable wpa_supplicant and systemd-network services:
sudo systemctl enable wpa_supplicant@wlp18s0.service
sudo systemctl enable systemd-networkd.serviceAnd reboot your PC to check if it works.
Also it's better to handle the /etc/resolv.conf file yourself if you use systemd-networkd. I use the Google DNS server. So my /etc/resolv.conf file is this:
nameserver 8.8.8.8
nameserver 8.8.4.4Last edited by pezzonovante (2014-09-01 13:53:54)

You may prefer to do that, but it is equally effective to use systemd-resolved, as described on the systemd-networkd wiki page.

Re: [SOLVED] Netctl failing where sole wpa_supplicant works
Backing up a bit and proceeding down the netctl branch...
Are you running dhcpcd as a service? If so, and if you are using nectl, don't do that. Netctl will start dhcpcd when it needs it. The dhcpcd service conflicts with this.

Not sure. There was no standalone dhcpcd service, but there was enabled a netctl service for wired network, which failed silently as no wire was pluged in. Anyway I disabled it, rebooted, but still the same error occurs.

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.
96 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.I suppose it would be nice to have it solved, because from what I learned so far systemd-networkd serves best for stationary computers that don't change network connections frequently. My machine is a laptop which I happen to journey with from time to time and since I have netctl already working with wired network, it would be nice to use the same tool for wireless.

Re: [SOLVED] Netctl failing where sole wpa_supplicant works
Failed to connect to non-global ctrl_ifname: wlp8s0 error: No such file or directory
It think that is wpa_cli, you could try if adding this to your wpa_supplicant/home.config helps

Re: [SOLVED] Netctl failing where sole wpa_supplicant works
Unfortunately my wpa_supplicant doesn't even recognize these commands:

Re: [SOLVED] Netctl failing where sole wpa_supplicant works
You need to put it above the network={} block, and be wary to not have extra spaces etc in the assignments, wpa_supplicant parsing can be quite picky
