Can't connect to wireless using NetworkManager unless killing dhcpcd

view story

https://bbs.archlinux.org – I've bought myself a new laptop (Asus UX31E), but I'm having trouble with getting it to connect to a network. Well, sort of at least. In order to establish a connection I have to manually run dhcpcd -x before trying to connect to the network. If not, NetworkManager says it couldn't connect. System is installed from latest install media (including systemd) and everything's up to date. As for DE, I'm running Cinnamon from the AUR. What do I have to do to avoid manually killing dhcpcd every time I boot the computer? snufkin https://bbs.archlinux.org/profile.php?i (HowTos)
