In order to create an AP on my Pi I followed this tutorial at adafruit, which seems to be very similar to many others on the web: https://learn.adafruit.com/setting-up-a-raspberry-pi-as-a-wifi-access-point/install-software.
I've just replaced "eth0" for "wlan1" as I'm using wireless connection and would like to replace it further by "ppp0" to establish 3G-WIFI connection. As you can expect when I get through the tutorial, it doesn't work :-) It seems HostAPD is configured for its visible in wifi networks list, but it isn't possible to connect to it. Perhaps something wrong with DHCP or bridge forwarding? The Terminal has been ioctl[RTL_IOCTL_HOSTAPD]: Invalid argument which has been fixed by downloading driver from Realtek's website but althought the AP is visible, it is still unable to connect to is as Terminal output of HostAPD is:

It seems that's something wrong with DHCP:
systemctl status isc-dhcp-server.service
● isc-dhcp-server.service - LSB: DHCP server

I followed the tutorial mentioned above and have no idea what could go wrong with setting up DHCP. My network interfaces file is below.
