Hello,
Setting up a WiFi AP using NetworkManager on Debian 11. I am beginning with NetworkManager as I want to get rid off a complex system just for setting the network on Linux machines.
Here the code I used to create the APAfter that the connection appears OK and the SSID is correctly broacasted but when I try to connect it fails. Trying from an Android phone and from another Linux machine.
Here the logs I have from the connecting Linux machine => looks that no IP address is returned (DHCP server not reacting or no DHCP server at all)
On the AP machine nothing meaningful appears in the logs even with the DEBUG level. Tried dhcpdump, but it is not yet installed.
I have looked any article explaining the use of DHCP server (dhcpd) with NetworkManager without anything useful found.
