Confliciting DNS network-manager

[zer02]

Hello,

 

I am trying to setup a hotspot with a static IP using hostapd, dnsmasq on wlan0, which is unmanaged by network-manager.

 

wlan1 is managed by network-manager, and uses dns=dnsmasq inside the network-manager.conf file.

 

I have disabled systemd-avahi-daemon.socket + service and deteded isc-dhclient-X (common), because it seems my DNS is conflicting.

Now it happens that the power management goes ON, on wlan1, altough I have wifi.power_save = 2. How can this all happen?

 

Just want to use /etc/network/interfaces the anachronistic way, but network-manager and other dns services from the beginning are conflicting.

Can anyone tell me, which services have to be disabled in order to just use this setup?

I am trying the last 4 days.

Thank you.

 

UPDATE:

Ntpd is deleting my device, why?
