              netctl wifi restart script.md
            
          
    restart-wifi.sh

I use this script because netctl is kinda annoying to use otherwise.
Change Wifi Device state

I've been turning off my wifi device using ip as follows:
ip link set wlp58s0 down

where wlp58s0 is my wifi device.
Use

To use set the first parameter to a wifi name with a configuration already set and placed in /etc/netctl
e.g.
$ sudo cat /etc/netctl/cplwifi
[sudo] password for sahal: 
Description='Automatically generated profile by wifi-menu'
Interface=wlp58s0
Connection=wireless
Security=none
ESSID=CPLWIFI
IP=dhcp

$ restart-wifi.sh cplwifi
