Install Software

Install DNS, DHCP, and AP-hosting software:

Set up DHCP

For dhcp we'll use the dhcpcd utility.

Edit dhcpcd config file

Edit /etc/dhcpcd.conf and modify it to contain this:

interface wlan1
    static ip_address=192.168.4.1/24
    nohook wpa_supplicant

replace wlan1 with whatever interface you want to use.

sudo service dhcpcd restart
