Please provide more information, so this bug report is actually useful.
E.g. follow the steps at

It contains hints how to file a good bug report.

Also, please use reportbug next time, so we have proper version

Tagging as unreproducible, since creating a hotspot works fine here.

Which tool/desktop environment did you use to create the hotspot?

A debug log from NetworkManager would have been helpful as well. That
said, your issue looks like a bug in the linux kernel/iwlwifi.

Have you tried older kernels (like the jessie one)?

Which log file should I get? I can't see anything in /var/log/messages
or /var/log/syslog

We tried 3-4 different laptops with different chipsets (some Ubuntu) and
none could create hotspot.

yes, I was on 3.14 and the same problem was there.

Well, see the wiki pages I pointed you at. They show instructions how
you can run NetworkManager in debug/foreground mode.

To get the  non-debug log messages, you can also run
journalctl -u NetworkManager.service

As said, it works fine here.

Jessie is 3.16 iirc.

A me-too doesn't really help. We need log files and details what makes
your setup special, to find out how this is triggered.

Do you have the proper firmware for this device installed?

Well, I'm able to use this device normally, I can connect to wifi access
points using this device, without a proper firmware I would not be able
to use the device. Also I updated firmware-iwlwifi and it still don't work.

When trying to see if hostapd work, I had run 'sudo rfkill unblock
wlan0', probably that was the case. No idea otherwise.

It was not working before I installed hostapd, now after removing
hostapd, the situation has not changed.

So, it seems to be wpa_supplicant, which is failing here.

Can you attach your /etc/NetworkManager/system-connections/Hotspot
connection file?
Please also run wpa_supplicant in debug mode and attach the log.

Try changing the Hotspot configuration to WPA-PSK and see if that makes
a difference.

I tried that, but it did not make any difference. I also removed all
Hotspot-* files from /etc/NetworkManager/system-connections and
recreated it, without any effect.

One noticable difference I see is, that g-c-c creates a Hotspot
connection here which has
mode=infrastructure. Yours has mode=adhoc.


Dan, are there any known issues with hotspot mode in ad-hoc mode?

Nothing known, no, but it's pretty dependent on the driver not being
stupid.  That said, best thing to get for debugging is the
wpa_supplicant debug logs to see what's going on in the supplicant.

I guess there is a duplicate bug for this one. It is #858870 and it has

Hello.

Any problem in creating hotspot in Stretch version of network-manager
(1.6.2-3). ?

I am able to create hotspot but other devices are not connecting to the
hotspot. The workaround I found is by installing network-manager (1.2
version ) from ubuntu repo.

Anyone having similar issue ?

Thanks.
