[arch-general] network setup help

[kqt4at5v at gmail.com]

I am having a bit of trouble getting my network connection working
Following "Systemd with wpa_supplicant and static IP" at 
https://wiki.archlinux.org/index.php/Wireless_network_configuration#Manual_wireless_connection_at_boot_using_systemd_and_dhcpcd

If I follow this exactly to interface will not come up
[root at grumpy10 ~]# systemctl -l status network-wireless at mlan0
* network-wireless at mlan0.service - Wireless network connectivity (mlan0)

If I change the "ip addr add" line and change $address/$netmask to 192.168.2.110/24 the interface will come up

[root at grumpy10 ~]# cat /etc/conf.d/network-wireless-mlan0
address=192.168.2.110
netmask=24
broadcast=192.168.2.255
