The issue or at least the latest issue turned out to be that the DHCP Daemon (DHCPD) was not starting.The DHCPD provides IP addresses to clients when they connect to the access point.
The latest init.d script to start DHCPD, scans the /etc/network/interfaces file and exits if it finds an interface set to DHCP.
The default file from M2P has such an entry so DHCPD never starts, causing the connect problem. In the file I had you download with „wget“
I replaced the dhcp entry with a static entry for eth0, and removed the dhcp setting for wlan0 as well.
BTW you will find M2P through the ethernet/wired interface at: 192.168.1.250 with the current setting.
