I would like to make router from my Raspberry Pi 3B+ using built-in wifi.
After installing the OS, I made update, upgrade and installed packages:
sudo apt update -y && sudo apt upgrade -y && sudo apt install dnsmasq hostapd rng-tools -y
I configured static IP by adding:
interface wlan0
static ip_address=192.168.130.13/24
static routers=192.168.130.1
static domain_name_servers=192.168.130.1
to /etc/dhcpcd.conf file.
Then I created /etc/hostapd/hostapd.conf file:
interface=wlan0
driver=nl80211
ssid=PI-AP
wpa=2
wpa_passphrase=raspberry
channel=6
and after running sudo hostapd /etc/hostapd/hostapd.conf ssid of this network should be visible on my phone, but its not.
I only got this error:
random: Trying to read entropy from /dev/random
Configuration file: /etc/hostapd/hostapd.conf

@EDIT
After fresh installation of Raspbian Stretch with desktop (version November 2018), using my laptop I created empty file called ssh and file called wpa_supplicant.conf on the boot partition:
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=IE
network={
ssid="My SSID"
psk="My WiFi Password"
key_mgmt=WPA-PSK
}
Then I added following lines at the end of the /etc/dhcpcd.conf file to configure my static IP address:
interface wlan0
static ip_address=192.168.130.13/24
static routers=192.168.130.13.1
static domain_name_servers=192.168.130.1
Then I connected to my Pi using ssh and executed following commands:
passwd
sudo apt update -y && sudo apt ugrade -y && sudo apt install hostapd rng-tools -y
Nextly according to instructions from: Access point as WiFi repeater, optional with bridge
I executed following commands:
sudo systemctl stop hostapd
sudo systemctl mask networking.service
sudo systemctl mask dhcpcd.service
sudo sudo mv /etc/network/interfaces /etc/network/interfaces~
sudo sed -i '1i resolvconf=NO' /etc/resolvconf.conf
sudo systemctl enable systemd-networkd.service
sudo systemctl enable systemd-resolved.service
sudo ln -sf /run/systemd/resolve/resolv.conf /etc/resolv.conf
Then I created file /etc/hostapd/hostapd.conf:
interface=ap0
driver=nl80211
ssid=SSID
country_code=DE
hw_mode=g
channel=1
auth_algs=1
wpa=2
wpa_passphrase=PASSWORD
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP
rsn_pairwise=CCMP
and I executed this command: sudo chmod 600 /etc/hostapd/hostapd.conf
Then I changed #DAEMON_CONF="" to DAEMON_CONF="/etc/hostapd/hostapd.conf" in /etc/default/hostapd and # Should-Start: $network to ## Should-Start: $network in /etc/init.d/hostapd.
Then I executed following command: sudo systemctl edit hostapd.service and I pasted this:
[Unit]
Wants=wpa_supplicant@wlan0.service
[Service]
ExecStartPre=/sbin/iw dev wlan0 interface add ap0 type __ap
ExecStopPost=-/sbin/iw dev ap0 del
Then I created file /etc/wpa_supplicant/wpa_supplicant-wlan0.conf:
country=IE
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
network={
ssid="My SSID"
psk="My WiFi Password"
}
and executed following commands:
chmod 600 /etc/wpa_supplicant/wpa_supplicant-wlan0.conf
systemctl disable wpa_supplicant.service
systemctl enable wpa_supplicant@wlan0.service
Nextly I executed this command: sudo systemctl edit wpa_supplicant@wlan0.service
and pasted following lines:
[Unit]
BindsTo=hostapd.service
After=hostapd.service
[Service]
ExecStartPost=/sbin/iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE
ExecStopPost=-/sbin/iptables -t nat -D POSTROUTING -o wlan0 -j MASQUERADE
Then I created /etc/systemd/network/08-wlan0.network file:
[Match]
Name=wlan0
[Network]
IPForward=yes
DHCP=yes
Address=192.168.130.13/24
Gateway=192.168.130.1
Nextly I add bridge=br0 at the end of /etc/hostapd/hostapd.conf file.
Then I executed following command: sudo systemctl edit wpa_supplicant@wlan0.service and my file looks as follows:
[Unit]
BindsTo=hostapd.service
After=hostapd.service
Wants=ap-bring-up.service
Before=ap-bring-up.service
[Service]
ExecStartPost=/sbin/iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE
ExecStopPost=-/sbin/iptables -t nat -D POSTROUTING -o wlan0 -j MASQUERADE
ExecStopPost=-/bin/ip link set ap0 up
Then I executed following command: sudo systemctl --force --full edit ap-bring-up.service and pasted these lines:
[Unit]
Description=Bring up wifi interface ap0
Requisite=hostapd.service
[Service]
Type=oneshot
ExecStart=/lib/systemd/systemd-networkd-wait-online --interface=wlan0 --timeout=60 --quiet
ExecStartPost=/bin/ip link set ap0 up
Finally I created following files:
/etc/systemd/network/02-br0.netdev
[NetDev]
Name=br0
Kind=bridge
/etc/systemd/network/04-eth0.network
[Match]
Name=eth0
[Network]
Bridge=br0
/etc/systemd/network/16-br0_up.network
[Match]
Name=br0
[Network]
Address=192.168.13.1/24
DHCPServer=yes
and I rebooted my Pi and after that it I still can't see the SSID of wifi and Pi is not connecting to my home wifi anymore.
