need internet access, this can be through ethernet direct

sharing via windows network connection center

or connection to wifi network

other

must set the wifi region on rpi

sudo raspi-config

localization Options

WLAN Config

Auto Setup

load files onto RPI run sudo bash wlansetup.sh follow prompts

Manual Setup

Run sudo apt install dnsmasq hostapd

then

sudo systemctl stop dnsmasq
sudo systemctl stop hostapd

open sudo nano /etc/dhcpcd.conf

at the bottom enter

interface wlan0
    static ip_address=192.168.4.1/24
    nohook wpa_supplicant

save and then type

sudo mv /etc/dnsmasq.conf /etc/dnsmasq.conf.orig

open sudo nano /etc/dnsmasq.conf

then type

interface=wlan0      # Use the require wireless interface - usually wlan0
dhcp-range=192.168.4.2,192.168.4.20,255.255.255.0,24h

start the dnsmasq sudo systemctl start dnsmasq

configure access point

open sudo nano /etc/hostapd/hostapd.conf

enter and change ssid, and password

interface=wlan0
driver=nl80211
ssid=NameOfNetwork
hw_mode=g
channel=7
wmm_enabled=0
macaddr_acl=0
auth_algs=1
ignore_broadcast_ssid=0
wpa=2
wpa_passphrase=8CHARPASSPHRASE
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP
rsn_pairwise=CCMP

any wrong typing here will cause the WAN to fail

enter sudo nano /etc/default/hostapd

find the line #DAEMON_CONF and replace it with DAEMON_CONF="/etc/hostapd/hostapd.conf"
