[SOLVED] Ubuntu forgets my network settings after reboot

[TBTsjG89]

I'm using Ubuntu 8.10 and every time I start my PC I have to set my network settings, otherwise Ubuntu loads its default values (dhcp). I'm part of a LAN, and I have a static IP, no dhcp.
I have tried editing the /etc/network/interfaces file, but its content does not even correlate with the settings I manually type in the GUI window.
This problem didn't occur before I upgraded my system from 8.04.1 TLS

thank you for your help in advance

I managed to solve the problem after an hour of googling. When you set your network settings, you must check the checkbox 'System setting'. For some reason it is unchecked by default. Doing this is necessary to make NetworkManager create a profile in /etc/NetworkManager/system-connections/, which will be loaded in the future.
I've attached a screenshot (scr.png) to my reply, so you can see what I mean.
Hope this will help somebody!
