[SOLVED] Wireless Connectivity Woes
I've been using Arch since November of last year, and I've finally come across one of those problems that is so irritating it's difficult to find the answer.
THE PROBLEM: Both myself and a friend of mine have found ourselves unable to connect to a wireless network on our laptops. We use wifi-menu to connect to a network which saves a netctl profile to use at a later date. We have wpa_supplicant installed.
SYMPTOMS: When we select any wireless network from wifi-menu, we are immediately returned "Job for 'netctl@etcetera.service' failed" and are told to check the service's status or journalctl -xn for more information. The information to be gathered there is null and void. Essentially just says that the service failed, but not why. I've attempted using DHCP_DEBUG='yes' and also setting the dhcp timeout to 30, but it had no effect. In fact, it didn't even wait for the timeout.
ATTEMPTS: I attempted to use NetworkManager and nmcli to resolve the issue to no avail. nmcli simply failed to connect. Enabling NetworkManager.service with systemd worked temporarily. Essentially, I could plug in a cable or connect to wifi with no problems, but the connection would only last around 30 seconds before giving up. Unplugging and replugging the cable would have the same effect, or I could restart NetworkManager.
NOTES: Not sure when it started happening (so don't know if it was an update problem). I have not RTFM for netctl, mostly because it's low priority (I use a wired connection most often).
This is something that's worked just fine for me since I started using Arch. Was there an update that caused this to happen? I use the latest version of everything, so I would have any of the newest bug fixes, but also the newest bugs.
If there's any information you need, I'll be happy to give it. Networking isn't my forte; it's always worked out for me.

Re: [SOLVED] Wireless Connectivity Woes
I think that posting service status and the output of journalctl would help.
It may be caused by services not running properly, thus I would suggest to disable netcl profiles and attempt manual connection procedures to debug the issue. For helping you in doing that I would need you to tell me how are you trying to connect: cable/wireless and if wireless what kind of.

Re: [SOLVED] Wireless Connectivity Woes
Can't seem to find a way to escape the character in the profile. However, this has happened with manually created profiles that do not contain hyphens in their names. Not sure what other information is needed.

Re: [SOLVED] Wireless Connectivity Woes
This might be relevant:
Both my friend and I recently had trouble connecting due to a "device is already up" message, so I set it down with `ip link set <device> down` which fixed that particular issue. Now, I can't seem to set mine back up using the same procedure.
$ ip addr

Re: [SOLVED] Wireless Connectivity Woes
Okay. So we've determined that the device is up. I now have a more relevant systemd journal:

You have dhcpcd.service enabled/started. This may be your conflict.

Re: [SOLVED] Wireless Connectivity Woes
I didn't realize that dhcpcd had a conflict with netctl. Does netctl work fine with wired as well, or do I just need to stop dhcpcd before connecting wirelessly?
The reason that this perplexes me is because this has never presented a conflict in the past.

Re: [SOLVED] Wireless Connectivity Woes
you can create 2 (or how many ever you want) profiles with netctl. check the /etc/netctl/examples directory on how to setup an ethernet profile and a wireless-* profile based on whether you use wpa or wep or open network. There are additional examples for EPEAP etc in there as well.
There's no such thing as a stupid question, but there sure are a lot of inquisitive idiots !

Re: [SOLVED] Wireless Connectivity Woes
Not necessarily solved, but I managed to get NetworkManager to work by doing the following:
# systemctl disable dhcpcd
# systemctl enable NetworkManager
# rebootFor netctl users, I imagine disabling dhcpcd will solve the issue.
