Do as indicated on https://www.raspberryconnect.com/projects/65-raspberrypi-hotspot-accesspoints/168-raspberry-pi-hotspot-access-point-dhcpcd-method.
Connected on the Raspberry Pi (directly, or using ssh), do the following commands:
sudo apt update
sudo apt upgrade
If needed:
sudo apt-get dist-upgrade
To install hostapd, enter the command:
sudo apt install hostapd
enter Y when prompted.
To install dnsmasq enter the command:
sudo apt install dnsmasq
enter Y when prompted
The installers will have set up the program so they run when the pi is started and activated them. While we set the hotspot we should stop them running. This is done with the following commands:
sudo systemctl stop hostapd
sudo systemctl stop dnsmasq
Define the hotspot network name and passphrase in /etc/hostapd/hostapd.conf (see ssid and wpa_passphrase properties):
# country_code=FR
interface=wlan0
driver=nl80211
ssid=NMEANetwork # <- This is the network name, choose your own. And remove this comment !!
hw_mode=g
channel=6
wmm_enabled=0
macaddr_acl=0
auth_algs=1
ignore_broadcast_ssid=0
wpa=2
wpa_passphrase=PassWord
wpa_key_mgmt=WPA-PSK
# wpa_pairwise=TKIP
rsn_pairwise=CCMP
Add the following lines at the bottom of /etc/dnsmasq.conf
# RPiHotspot config - No Intenet
interface=wlan0
# bind-dynamic # Add this for Internet config
domain-needed
bogus-priv
dhcp-range=192.168.50.150,192.168.50.200,255.255.255.0,12h
Add the following lines at the bottom of /etc/dhcpcd.conf (make sure you use the right file... dhcpcd.conf):
#
# Static HotSpot
interface wlan0
nohook wpa_supplicant
static ip_address=192.168.50.10/24
static routers=192.168.50.1
Enable the hostapd and dnsmasq services:
sudo systemctl unmask hostapd
sudo systemctl enable hostapd
sudo systemctl unmask dnsmasq
sudo systemctl enable dnsmasq
See their statuses:
sudo service hostapd status
sudo service dnsmasq status
Notice above, the network name and password:
- Network name is
NMEANetwork - Network password is
PassWord
Those values cane be change as you wish.
Once the above is done, you can reboot the Raspberry Pi.
