Hi Elias, sorry the command should have been sudo systemctl -i status hostapd,

From your last log it seems dnsmasq is not finding wlan0 so didn't start the wifi but found eth0. so we need to find what config is causing an issue so wlan0 is not available.

If wlan0 is not starting up then there also could be an issue in /etc/dhcpcd.conf.
Double check the line; interface wlan0 is correct and ends in a zero not the letter O

Can you do the output of sudo systemctl -i status hostapd and sudo systemctl -i status dnsmasq again please and also sudo systemctl -i status dhcpcd Could you paste them into the "Leave a comment" box, the Report link you have used makes a mess of the text so it is not very readable, thanks :)

Also manually start dnsmasq and hostapd and see what happens,
enter: sudo systemctl restart dnsmasq then sudo systemctl restart hostapd
and see if there is any issues with the commands sudo systemctl -i status hostapd and sudo systemctl -i status dnsmasq

if you can't see the issue you are welcome to send me you config file to admin@ this site
/etc/dhcpcd.conf
/etc/dnsmasq.conf
/etc/hostapd/hostapd.conf
/etc/default/hostapd
/etc/network/interfaces
/etc/iptables-hs

and I will check it out on my pi.
