Hi guys
I'm trying to use NM to start a WiFi AP mode. I've had some success but a
big portion of the process is very unclear to me and I'm hoping to get some
help.
So I have this NM configuration:
# cat Hotspot
[connection]
id=Hotspot
uuid=3e13073d-6d7a-440d-ab2b-4f42c9fdacaf
type=802-11-wireless
autoconnect=true
[802-11-wireless]
ssid=AliAP
mode=ap
security=802-11-wireless-security
[802-11-wireless-security]
key-mgmt=wpa-psk
psk=alisecurepassword984364@234@
[ipv4]
method=shared
[ipv6]
method=auto
With this, the NM starts up and does what it needs to do (I think):

So WLAN0 is up. Great!
When I was using "iw" and stuff to set up my AP, I used to start hostapd
and udhcpd to set up the IP address, and start broadcasting the SSID.
When I get to this point with NM, I was under the impression that NM would
take care of all of this. But I cannot see my SSID on my phone. I do have a
functioning wpa_supplicant btw.
Out of curiosity, I started hostapd and udhcpd. I could get hostapd to work
(but not the SSID I set in NM!!) and UDHCPD never worked.
I was wondering what I was missing in this and how I can start the
broadcast and activate the DHCPD automatically with NM.
I'm running NM 1.0.10.
Thanks!
