1. Enable wifi by setting country code => https://steemit.com/raspberry/@corvex/raspberry-pi-stuff

2. update
   => sudo apt update && sudo apt upgrade -y

3. Install hostapd & dnsmasq
   => sudo apt install -y hostapd dnsmasq

4. Configure Static IP for WiFi
   => sudo nano /etc/dhcpcd.conf
   add following at the EOF:
   --
   interface wlan0
   static ip_address=192.168.4.1/24
   nohook wpa_supplicant
   --
   => sudo service dhcpcd restart

5. Configure hostapd
   => sudo nano /etc/hostapd/hostapd.conf
   add:
   --
   interface=wlan0
   driver=nl80211
   ssid=YourNetworkName
   hw_mode=g
   channel=7
   macaddr_acl=0
   auth_algs=1
   ignore_broadcast_ssid=0
   wpa=2
   wpa_passphrase=YourSecurePassword
   wpa_key_mgmt=WPA-PSK
   rsn_pairwise=CCMP
   --
   => sudo nano /etc/default/hostapd
   update following line
   --
   DAEMON_CONF="/etc/hostapd/hostapd.conf"
   --

6. Config dnsmasq
   => sudo mv /etc/dnsmasq.conf /etc/dnsmasq.conf.bak
   => sudo nano /etc/dnsmasq.conf
   add
   --
   interface=wlan0
   dhcp-range=192.168.4.2,192.168.4.20,255.255.255.0,24h
   --

7. Enable IP Forwarding (if needed)
   => sudo nano /etc/sysctl.conf
   uncomment this line:
   --
   net.ipv4.ip_forward=1
   --
   => sudo sysctl -p

8. Restart services
   => sudo systemctl unmask hostapd
   => sudo systemctl enable hostapd
   => sudo systemctl start hostapd
   => sudo systemctl restart dnsmasq

If the dnsmasq service starts before the wlan0 gets initialized, do this aswell:

=> sudo mkdir -p /etc/systemd/system/dnsmasq.service.d/
=> sudo nano /etc/systemd/system/dnsmasq.service.d/override.conf
