Thank you for this script! I tried it on a raspberry pi 4 and it works fine, just with some changes.

I had to remove from /etc/hostapd/hostapd.conf

ctrl_interface=/var/run/hostapd
ctrl_interface_group=0

After reboot both ap0 and wlan0 got an IP, but something still feels wrong. Accessing the pi from ssh ( through eth0 ) was jittery. Also checking ip monitor I was getting a lot more logs than usual

I also noticed that on system status hostapd I get the following error:

May 06 15:33:35 raspberrypi systemd[1]: hostapd.service: Scheduled restart job, restart counter is at 1329.
May 06 15:33:35 raspberrypi systemd[1]: Stopped Access point and authentication server for Wi-Fi and Ethernet.

May 06 15:33:35 raspberrypi hostapd[44157]: nl80211: deinit ifname=ap0 disabled_11b_rates=0

I then removed ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev from /etc/wpa_supplicant/wpa_supplicant.conf and this seems to have improved the problem. No more jittering and ip monitor log looks more normal. But I also lost the ability to use wpa_cli

I wonder if there's a better solution than this that can allow me to use wpa_cli

I am just curious if the ethernet worked on your RPi 4 after the installation.

I couldn't get it working because there is no such interface..
But I can see it in /sys/class/net/eth0.

Thanks!

It's been a while, but I followed this guide and got it working: https://www.raspberryconnect.com/projects/65-raspberrypi-hotspot-accesspoints/168-raspberry-pi-hotspot-access-point-dhcpcd-method

Thank you for posting this issue! It solved my problem too. Not sure why this is the case either. But I didn't have to do anything above with hostapd since my hostapd service was masked.
