[Solved] NetworkManager give me wrong routing

Hello,
I have a desktop PC, which is set as server for the family. The server is set mainly for DLNA, some file sharing and ad-blocking (next page caching).
Lately I added an AP, connected by Ethernet cable. I set forwarding to allow whom will connect to the AP to go to Internet. The desktop PC is connected to Internet via USB-WiFi dongle.
So my setting are:

• desktop 192.168.1.2 >> ISP router 192.168.1.1

• AP 192.168.2.1 >> desktop 192.168.2.2

• Incoming connections 192.168.2.3/24 to AP

• incoming connections have also the option to go directly to ISP router, but the router gives a lot of timeouts.

When I use the gnome-applet to connect NM to ISP router, I get the right routing. default gw 192.168.1.1 wlan0
If I connect the Ethernet, I'll get default gw 192.168.2.2 eth0, which goes nowhere. For that case I do manually add

# route add default 192.168.1.1 wlan0

So I'll get things going again to let all connect to internet.
My question is about to know the setting for NM (or by the gnome-applet) to do me the correct routing, without manual intervention.

EDIT
I finally found the right answer
