Troubleshooting • Creating a WiFi hotspot

Used to have this working fine in Debian using `brctl`, `hostapd` and `dndmasq` ,

I bridged wlanE and eth1, ran hostapd on wlanE, and dndmasq on br0. All was good.

Unfortunately networking has been replaced with some offensively bad thing called `NetworkManager` -- a wheel that really didn't need reinventing -- especially since it simply doesn't work.

I followed the instructions at https://raspberrytips.com/access-point- ... pberry-pi/#

Code:

sudo nmcli con add con-name AP-kestrel ifname wlanE type wifi ssid kestrelsudo nmcli con modify AP-kestrel wifi-sec.key-mgmt wpa-psksudo nmcli con modify AP-kestrel wifi-sec.psk "top-secret-password"sudo nmcli con modify AP-kestrel 802-11-wireless.mode ap 802-11-wireless.band bg ipv4.method shared
The AP appears, but nothing can connect to it. No messages in `journalctl` about what could be happening.

Also, the interface gets a `10.10.` address (it's unclear how or why -- there's nothing in `/etc/network/interfaces`), and it's not clear whether it's routable with the rest of my home network.

WTF is going on?
Can it still work?
Can I get rid of this dreadful NetworkManager crap and get back to normal?
