TL;DR: What could cause netctl to suddenly stop working? I didn't make any manual changes to the profile I was using, and am unable to get it to work again by re-creating the profile.
So I installed Arch a few days ago, followed the beginners guide and got everything working basically without a problem. Rebooted, set up the network stuff, and everything went fine for a couple of days, and then yesterday it simply stopped working for no real apparent reason.
At any rate. Now I'm getting:
Job for email@example.com failed. See 'systemctl status firstname.lastname@example.org' and 'journalctl -xn' for details.
In looking into the systemctl status etc. it's saying that the WPA Authentication/Association failed.
I went through a bunch of older forum threads started by people with similar problems and tried many variations to no avail, as well as looked at some information here, and on the wiki.
What I've tried:
- Disable, enable, and ultimately deleted the profile and remake using wifi-menu, with and without the -o flag
- Disable, enable, and finally deleted the profile and remake manually using the examples
- Set up, and troubleshooting guide at the Arch Linux wiki for netctl
There is also a second interface (exactly what it is I really don't know, honestly. I'm on a desktop with just a wireless USB dongle), which I tried all of the above on as well.
systemctl status email@example.com:
firstname.lastname@example.org - A simple WPA encrypted wireless connection Loaded: loaded (/email@example.com; static) Active: failed (Result: exit-code) since Mon 2014-10-20 14:12:30 UTC; 9s ago Docs: man:netctl.profile(5) Process: 3054 ExecStart=/usr/lib/network/network start %I (code=exited, status=1/FAILURE) Main PID: 3054 (code=exited, status=1/FAILURE) Oct 20 14:12:14 DayStar network: Starting network profile 'wlp4s0-node'...

journalctl -xn Has some stuff about it failing but the relevant, I assume, lines are:
.... Oct 20 14:11:20 DayStar systemd: Unit email@example.com entered failed state. Oct 20 14:12:14 DayStar network: Starting network profile 'wlp4s0-node' Oct 20 14:12:14 DayStar kernel: IPv6: ADDRCONF(NETDEV_UP): wlp4s0 link is not ready ....
subsequently going into the bit about WPA association/authentication etc. I'd say perhaps it's just a hardware problem or some such but the USB dongle is how I'm connected now. Just through Windows instead of Arch.
